LaFigaro 339: My Fav OTL Amp

Our more frequent readers might have noticed me talking about or comparing amps to the La Figaro 339 and some have even asked for a review about it. So here is a long overdue write-up of the LaFigaro 339 OTL tube amp after having owned it for a little over 1 year.

For those of you who don’t know, La Figaro is a Chinese based company run by a guy named Liu Yi also known as “Yuking09”. It was founded in 2009 after he had left the maybe more famous Darkvoice because of (to us) unknown reasons. You can clearly see the similarities of the amps when looking at pictures of all the models on Google. Yuking’s statement is that he improved the Darkvoice designs even more giving an even better listening experience to the customer. The 339 is the La Figaro version of the DarkVoice 337, but upgraded. Here’s what LF had to say: “The output capacitors of 337 series machines is only 50μF but 339 is 130μF, so 339 have more strength in the bass, the structure of 339 is more reasonable, the pipe is on the front far from the the transformer avoiding interference. Especially with low impedance, the headphones can be very clear, 337 has a mild hum when it running low impedance headphones. 339 has better components, tubes: RCA socket by CMC and Headphone socket by Neutrik both make reliability better”.

The 339 explained

First let me get into some more details about the more or less 10kg! heavy 339. It is a dual mono design OTL amp. It has no Output Transformers and the vacuum tubes directly drive the headphone with no intervening transformer. The result, according to the designers using this principle, is an unbelievable clarity and realism that no other configuration can achieve. The output transformer is said to be a major source of distortion and amplifiers without the output transformer therefore produce cleaner, less distorted sound. OTL amps are mostly made to power higher impedance headphones and speakers and the prices can be rather high as the assembly is manual.

The dual mono part basically means the amplifier has two of everything. The left and right channel are built in parallel and both have their own power supply unit (PSU). That means two power cords (the voltage is set in the lab) and two separate volume controls which I will come back to later. The 339 has only one set of inputs and one single ended headphone out (plug by Neutrik).

On the inside of the amp you can find some very impressive point to point wiring that even impressed my amp doctor when I paid him a visit. He especially liked it because it is much easier to work on in case of problems as you can easily find and replace the malfunctioning component. It measured absolutely perfect for an amplifier he said, he didn’t have to change anything. The LF339, because of this dual mono configuration, uses two input tubes and two power tubes. The input tubes can be 6J4P, 6Ж4С, CV849 and 1852 (+ all equivalents). The accepted power tubes are 6N5P, 6N13P, 6080 and 6AS7 (+ all equivalents). You can also get supplementary adapters from La Figaro so you can use EF80, EF800 or EF86 type input tubes. The 6AS7(G) power type tubes are known to be noisy but that really depends on your tubes: some hum only in the beginning of their life cycle, some only when you start to use them, others will always hum and some never do. It’s a bit of trial and error really, the pleasures of tube rolling.

For some reason LaFigaro has never been very open about the metrics/power of this amp, they just keep stating the 339 will deliver around 800mw – 1w per channel throughout 25Ohm – 600Ohm. Out of experience I can confirm that using more powerful power tubes like the famous and nowadays expensive Tung-Sol 5998 do up the output power (Jack Woo from Woo Audio stated his WA2 gets 10% more power when using these tubes). The amplifier does run fairly hot and the whole casing serves as a heat sink. I’ve measured the temperatures of the amp at 3 places (case, vent, tubes) and after 1 hour temperatures already reached respectively 95, 176 and 163 (35°C, 80°C, 73°C). However don’t let this scare you as this is nothing to worry about at all, just keep it away from kids (like any tube amp).

The Design of the amp is basic. You love it or you hate it and I personally absolutely adore the way it looks. From the first time I saw the amp I’ve found it looking powerful and sexy (can an amp be sexy?) and I wanted to have it. The 339 is only available in grey as the pictures show (at the end of the article) and it has a nice 339 sign with 2 small green leds incorporated on top of the amp, only the cooling vent kills the top look a bit to my feeling. As mentioned in the paragraph above the amp can run quite hot and with kids walking around wanting to touch those nice glowing tubes this could lead to some unplanned visits to the hospital emergency service. To protect the kids from the tubes (or is it the other way around?) you get a tube cage to put over the tubes but it really does destroy the look of the amplifier imo.

On the front of the amp you only have the headphone out and the dual volume controls, making it a simple symmetrical design. The dual volume controls have advantages and disadvantages but it has never bothered me. There were multiple reasons Yuking incorporated them in the design, while it wasn’t absolutely necessary. First of all not everyone’s left and right ear is equally good and with this separate control you still get the same volume left and right. Second, not only human ears can be wrong but your power tubes might be of different strengths too, just like your headphone could be a little off (like my HE-400 Rev 1). With all the tubes I used so far I never had to pass 11 o’clock, there’s plenty of room to work with. Both volume controls, like the amp itself, are dead quiet when turning.

Looks, in contrary to the internal design, aren’t the most important part of an amp (but they’re important too in my regard) and each time it comes down to how a unit sounds. From the first time I turned on the amp however I was genuinely pleased with its performance. While the OTL amps are most likely to perform well with high impedance headphones, the designer made sure his amp also sounded good with low impedance phones. The only low impedance headphones I have however are orthodynamics, so I’m afraid those are the only ones I can comment on.

How does it sound? + Tube rolling

Overall the 339 amplifier can be described as having a very tube-ish sound with a warm and smooth sound signature. Sound stage wise the 339 does very good, it has a great wide sound stage that even improves when using the famous 5998 tubes by Tung-Sol. It’s a very natural sounding amplifier with great dynamics and detail. The mids are warm and smooth with a slightly rolled off treble. You won’t really like it if treble is your thing but this can be improved using other tubes. (I my selection of tubes, most have the rolled off highs). Bass is nicely detailed, very deep and punchy but not as tight and punchy as say with one of the solid state Violectric amps.

The big advantage of this amplifier is that tube rolling really allows you to change the sound signature of the amplifier. With the stock tubes, which I didn’t listen to a lot, you get a much more forward sound and detailed treble but you lose the smoothness and bass compared to most “aftermarket” tubes. After lots of tube rolling (you can ask for details in the comment section if anyone is interested) I settled on two different sets of tubes. First of all the RCA 6AS7G power tubes with a Telefunken EF80 (using the adapter from La Figaro) and secondly a pair of Tung-Sol/Chatham 2399 tubes (5998 equivalent) combined with the Red RCA 5693. Both combinations have the same kind of sound: warm, smooth, good bass and the right amount of treble. The big difference is the 2399 set improves everything the first set does, it gives you an even bigger sound stage, more focused bass and more detail while remaining smooth and warm. Another advantage is that these tubes deliver more power too. In example with the LCD-2 were the first pair easily needs 11 o’clock on the dial, the second set of tubes only needs 9 o’clock. But one shouldn’t be afraid of the 339 not having enough power, I can assure you that’s not the case.

I have to say, how wrong it might sound, that I love all of my headphones with the 339 but the ones standing out most are the Sennheiser HD600/650 and the Hifiman-HE500. The Sennheiser – 339 combo is really a match made in heaven and I have never heard the Senns sound as good as with this amplifier. When I have people over, even those not knowing much about audio, they all put this combination on the first place of the podium. It’s just that good, warm, smooth and detailed. The perfect Sennheiser sound with good bass and detail. In second place comes the HE-500, the 339 even with the least powerful set of tubes drives it perfectly. The Violectric gives it more power and tighter bass and makes it a little more spot on with more forward and precise treble but the 339 just makes it so smooth sounding and lush you dream of being in that dark and smokey jazz club 50 years ago with the sexy female singer on stage who’s winking at you while you take a sip of your whiskey. If music and your setup can do that, you’re set for a long time if you ask me. Another of my favorite headphones with the more powerful setup of the amp is the LCD-2. While not at the same level as with the Violectric V100 and V200 the Audez’e still is very good sounding. It’s nice to switch between the different amps depending on the sound signature you’re looking for but there are better amps out there for the LCD-2. Two headphones that didn’t perform that great with it are the DT990/600 (a solid state amp in my experience can get more out of them) and the Hifiman He-400. These “bass loving” headphones both get better results using a solid state design.

OTL Amp comparisons

Compared to the Bottlehead Crack, the OTL Crack is the faster amp of the two, it it clearer sounding and focuses more on the treble. Bass with the Crack is punchier but not as deep and it doesn’t quite have the same rumble. Overall the 339 is smoother, warmer and laid back with an even bigger sound stage. It just makes you feel the music better (softer) as the crack. The Crack is a great deal and an excellent amp as we already said in our review but the La Figaro 339 is the better amp for me. Compared to the Woo Audio 2, the 339 is the more tube-ish sounding amplifier with a much warmer sound. The WA2 sounds much cleaner and faster but misses the warmth and soul I like of the 339. The WA2 is more analytical as the 339 and the bass depth and rumble isn’t quite the same, however it does have an even bigger sound stage. Most likely a full WA2 review will follow later.

I’m sorry if this review was too long and positive but in all honesty, I really find it that good. The La Figaro 339 is available from Yuking09.com directly and costs $550 without shipping. A price that I think is “a steal” for such a great amp. I’m convinced that if this amp was built in the USA or Europe it would get a lot more praise (as it deserves) and a higher price tag. If you would like a custom made amp you can always contact La Figaro, I’ve seen him do several impressive custom designs for clients all over the world.

      Depends on where you are and what your budget is I suppose. My GEC in example only cost me $20 NOS. A very good tube combo with the 339 as said in the review are the RCA 6AS75 which you can get everywhere for like $15/pice with the telefunken EF80 around $10/piece, I wouldn’t say that is expensive or hard to find 😉

        Well, you do get tons of NOS tubes in Hong Kong. Just that I don’t know whether a NOS TS5998 for $120 is justified compared to a used strong TS5998 for $75 is worth it.
        Sometimes you do get rare tubes popping up on second hand forums here, but only more “popular” tubes based on what amps are available in Hong Kong. Most tube amps here are Chinese DIY and only recently the LaFigaro, Schiits and Woos have been popping up in Hong Kong stores.
        Perhaps if the LF339 was more popular then maybe a market of 6AS7s might just surface, I mean we pay $550 and only that since there’s no extra charges to ship it next doors from China

        There’s always Taobao with plenty of tubes and the prices aren’t exactly cheap, in fact they’re the same as ebay. Although this really does surprise me… GEC 6AS7 for only 590 Yuan?
        http://item.taobao.com/item.htm?id=14438003185

        I don’t dare buy off Taobao, but is it theoretically possible to fake these tubes? Especially the dimple plated 5998 and 421A?

          There are lots of fake tubes on the chinese market. MY tube guy even showed them to me, they even copy the 50 year old boxes. I don’t know if these are fake though. 6AS7G should be farely easy to get of ebay

          Hi there,
          I actually recently bought the LF339 from your recommendations here and head-fi.

          I’m actually in HK as well and I’m looking at some tubes on taobao, but I’m quite afraid that they’re fake.

          If i’m looking for the Telefunken EF80 and RCA 6AS7G in Hong Kong for the prices you mentioned, where should I go? WIWI tubes? I really don’t know of too many places around here, I’m still quite a newbie.

          Thanks!

            Wiwi definitely has the biggest supply, their tubes are usually good but the prices are on the high side.
            Your best bet are trusted eBay sellers as the 6AS7G is really meant to be, an inexpensive tube. For the common tubes, avoid Wiwi. For rare tubes, Wiwi will have them but for a premium.

            Problem with the EF80 and 6AS7G is that they’re lesser popular tubes so they’re not really abundant in Hong Kong. I’m not currently in Hong Kong so I can’t tell you more than what I already know, but from my experience I didn’t manage to find any variety of the 6AS7G family. I ended up buying them off ebay.

      It’s not thaaat hard finding matched 5998’s or 7236’s. Sure. For a good NOS pair you end up paying about 150-180 USD, but just a couple of days ago a matched (used) pair of 5998’s ended up at 60 USD on eBay. One must also have patience if one wants to reach audio nirvana with minor bumps on the economic highway. 😉

          Exactly. Some of us are compulsive searchers. Each day I do a “5998 tube” “2399 tube” “421A tube” and “7236 tube” (in addition to “5693 tube”).

          One can never have too many of these babies in stock… I got 2 x 3 matched (2 + 1 extra) 5998’s, 3 x 2 matched pairs 7236 and 2 matched pair of 5693’s. Better stock these babies up. OTL never goes out of style and these are the holy grail of OTL-tubes. 🙂

              Merlins are fantastic though, but I mostly use them portably. LCD-2’s however… Sound like their bigger/badder big brother (even from The National + CLAS) , but especially from LF339.

    I don’t entirely understand the reasoning behind the dual power inputs – unless each side actually draws in excess of 6.5A/1.5kW (assuming that you have 13A max rated mains at 240V) there’s no reason to not just have one power inlet and run it to both power transformers. I’ve built amps with twin transformers and it’s no problem to just run two sets of wires from one inlet. I suppose it means no mains wiring running past the input or any audio sections, but it still seems excessive to me.

    Yuking also informed us that the new 339 has got new modifications making it a warmer sounding amplifier. I’m not sure I would like an even warmer amp, but I’d have to listen to it first. (+ it depends on the tubes used)

    He also confirmed their development of a power amp is almost completed.

    Hi! Yes an OCC cable will help you counter the brightness. Now for the 5998 tubes, they’re not the warmest tubes around but they do have more power. In my opinion you’re better of with cheap RCA 6AS7G if you need warmth and don’t need the extra power of the TS tubes.

    In example, the WA2. I prefer the RCA tubes there too cause the TS 5998 remove the warmth from the amp. So I’d suggest trying the RCA tubes first and then the copper cable

    • Reply August 22, 2012

      The TS5998 is more linear than most 6AS7 s so it is somewhat better off with the HD650. The RCA 6AS7G has slightly rolled off highs so it may be better for the HD800, and well and if it really does roll off too much try compensating with the RCA cleartop 12AU7/ECC82 for the input

    Hi Mike, i love your reviews about things here. You seem to know what you are talking about. I have a question, Im about to buy Some reference headphones to mix with, im making both electronic music and alternative hardrock. And im looking at these headphones from beyerdynamic, the DT880, i know that you adored the HD650.. I have an PIoneer Amp to push out alot of power to drive The HD650, but i dont know why im more into DT880 right now.. SO, now i need an Amp, which amp would the the choice for you for both DT880 & HD650, (if i buy DT880 now and Hd650 later), im relatively new to reference headphones & headphone amps,(just own a couple of old AKG 240 i think with 500 ohm) but i know about sound.. The thing is that i want a flat signal and a good amp with good components.I dont want the headphones to lie to me. Sorry for the long text, and answer would be highly appreciated!! // Kimmo from Sweden

      This should be in the Q&A section but HD650 isn’t really the best for the job. in fact neither the DT880 nor HD650 could be considered linear, HD650 rolls off on highs and the DT880 is treble hot. And HD650 is definitely not the cans for Electro and hardrock, i know because i listen to j-pop alot and the HD650 could definitely not keep up with the electric pace. Not too sure about the DT880 but it is definitely not slower than the HD650. Linear sounding would be something like the HD600 but the PRaT may still be insufficient. I would recommend closed cans for mixing such as the M-50, or the Senns HD-25II because they’re more of DJ cans and have good PRaT. There’s also the AKG K550 which is really linear but still doesn’t match the PRaT of the 2 closed cans ive mentioned

        The Beyers were designed for monitoring originally, and since you do have a full size amp I’d recommend the DT800 with the 600 Ohms rated impedance. The higher impedance Beyers are fairly linear actually.

    $500, you’re spoilt for choices really. Although I don’t prefer Burson too much, I seem to prefer slower paced DACs with more warmth for Senns HD650.

    And don’t worry. Headphones were never the most expensive part of the setup. People drive the Senns HD650 out of $1k+ amps

      Right now I think the Bottlehead Crack is the best amp for the HD650 sub $1K. The amp is just brilliant with the HD650.
      DAC, go with the HRT Music Streamer II+ or the Centrance Dacport LX.

        So is the “best” amp under the $1k mark the Crack or is it the LF339? Or rather the LF339 is just your preferred amp of the two? Just curious

        Oh and in the meantime, I think my total investment in my Crack is going to exceed the $550 pricetag of the LF339… going to throw in large film caps in like everyone else that can’t get enough of Crack

              for the Sennheiser sound that is. I think we could conclude that those two amps are worth every penny spent under the 1k, which one anyone would prefer would be the best to them. The two amps do have a different sound afterall, between the warmth of tubes and the clean sound of tubes. The synergy of these two amps with the HD650 does put away the Bursons and Schiits quite easily if I were to say, and probably the Graham Slees as well. Tube amps really do shine the most with the Sennheiser sound. L. likes his Senns warm and smooth, I like my Senns to sound clean with a tinge of warmth in it. Afterall, opinions are purely subjective.

              Just like how people think Monster Beats have the best bass out there.

          I think I’ve mentioned up there about the best sources and down below for best amps but here are your sub 1k choice amps which were all apparently “built with the Sennheisers in mind”

          Solid State/Tube Hybrid:
          Schiit Asgard, Vahalla – Was once the “bang for the buck” until the Crack showed up and just owned them.
          Graham Slee Solo SRGII – Most most tubey solid state you’d ever find. Small footprint, ginormous sound.
          Burson HA-160D – To knockup the pace of the slow Senns

          Tube Amps:
          Woo Audio WA3 OTL – With the Crack around, I don’t see why you should go for this.
          LaFigaro/Darkvoice 336 OTL – Same as above, but it’s price tag puts the Woo Audio to shame.
          LF/DF 332C/S – Don’t know much about this. Price sits between the Crack and the LF339, you may as well pick one of the latter, might get back to you if I manage to audition this.
          Woo Audio WA6 – Output transformer coupled. Mike noted it to have wider soundstage but less depth. Reaches its maximum potential with a very good 274B tube which would put it way beyond the 1k mark.
          Crack – Cleanest sounding OTL, great depth and potential mods if you really want to put all that 1k of your budget into your amp. With the Speedball upgrade, improvement from rolling in tubes are more evident.
          LF339 – Warmest and tube-iest of them all. L. loves it for making music sound like he was there having a drink down at a pub with some hot gal on stage. Pit it up against the branded solid state amps and the Woos, makes it look like the Chinese are offering you a budget solution… which also happens to sound the best as a true tube amp.

          Comments are purely subjective. I just think that my Crack rocks while it’s on Crack, that is these giant caps shoved into it

            Thank you for your reply. Right now I have NFB12.1, which is too warm for my taste, as HD600 are also warm. So it’s ok just to use CRACK alone, or would you use NFB12.1 as DAC and preamp, and add CRACK only as amp? So use them together… NFB12.1 -> CRACK, or sell NFB and use only CRACK?

            • Reply September 9, 2012

              Nick Tam

              Thing is I don’t really have experience with Audio-Gd and according to Mike’s impressions and the rest of the crowd, I’m not too sure how I would put it. Some say it is warm, Mike says it’s neutral but just lacks something. All I can say is that the Crack sound is very clean and is sitting on neutral, slightly leaning towards warmth depending on which tubes. Besides, if you sell your NFB, what are you going to use as your source?

              If the Audio Gd does sound as Mike says it sounds, then maybe you’ve found a very good pairing with the Crack. Otherwise, you may as well consider another source if it is too warm to begin with.

              • Reply September 9, 2012

                Peter

                As source? So Crack is only amp, without DAC, right?

                Acording to Mike, not all audio-gd products are bad. For example, he was happy with reference 7.1. He was just not happy with NFB12. But now, there is newer NFB15.1, or NFB11.32.

                Also, DAC part on NFB12 is pretty good, just amp part is little behind. So, combo NFB12 (as DAC) and CRACK (as amp) theoreticaly can be very good.
                I hear it on my active studio monitors… when I was switching to NFB12 from Xonar D1, I’ve noticed, that active studio monitors sound improved more, than headphone sound. That’s the proof, that weak part of NFB12 is amp, not DAC.

        My mistake, in that case, great review Lieven! Sorry about that. I am inclined to wait and save a bit more for the 339 after reading your review, however the tubes you used takes me way beyond my budget. Would you say it’s still worth it if I were to use the stock Chinese tubes for the foreseeable future? If it matters, I’ll be mostly listening with my AKG 550 and 702’s.

        • Reply October 18, 2012

          From my experience stock tubes give a more laid back approach with a syrupy mid (which isn’t a bad thing if that’s what you’re looking for), and the tubes that Lieven uses give a more powerful, forward presentation, while retaining detail and smoothness.
          For reference, I couldn’t listen to the LCD-2 (which has a rather forward presentation) with the Tung Sol 5998 and RCA 5693s. I thought the overly forward presentation killed some of the micro-details and I would experience fatigue after 2 hour listening periods. However, I could listen to the LCD-2 with enjoyment on the stock tubes. All a matter of preference.

            Yes Vern is right, it depends on your preference. I also really enjoy the cheap and easy to find RCA 6AS7G combined with the also easy to find and cheap Telefunken EF80 (adapter needed). When I’m not using orthodynamic headphones I find this combination to be the best. It’s true that the 5998/5693 is a bit more forward but the HE500/LCD2 need the extra power to sound better.

            Anyway to get back to your question. I didn’t like the stock tubes at all. The RCA’s and EF80 would set you back like $70 or so and give a smooth sound with good bass and easy treble. I fully recommend it as starter tubes and I think it would pair nicely with the 702s

      It’s been a while since I used the T70 (a friend is loaning it from me). I prefer the T70 on tubes to counter its character a bit. I don’t mind the T70 sounding a bit warmer and slower as on a SS amp. On the 339 it was best with the warm and smooth sounding RCA 6AS7G tubes with great bass. I think it would be too analytical on the WA2 but to be honest, I haven’t tried it yet with the WA2.

      The WA2 is a long term review, don’t expect it any time soon. So far the WA2 is best (awesome) used as a preamp. Actually for the moment I think it makes a better preamp as it makes an amp. And I know for one the WA2 owner agrees on that, and he’s a guy with dozens of top amps in his collection. Anyway, I need more time for the WA2. Sorry 🙂

      A tube amp would definitely help the EX1000 but I’m not sure about using a big gain desktop amp with an IEM.

      The Portaphile 627 amp is a much better suggestion for IEMs looking for smoother highs and more mid body (like the EX1000).

      Hi Martin,

      the WA2 for the moment is using RCA 6AS7G as I like their sound best. warmer with good bass and not too spiky treble. I do not like the sound of the 5998 type tubes, too much gain. As rectifiers I for the moment use EZ81 Mullard tubes or the Philips Miniwatt EZ80 but I find the rectifiers not to influence the sound in the WA2 a lot. And then finally I am using the Philips EGC made Siemens 7308 (these exact ones: http://www.upscaleaudio.com/products/Siemens-7308.html)

      This combo gives the WA2 the warmest and smoothest sound to my liking

            Without further experience, I decided on the WA2 as I wanted to pair and experiment my HD 650s with an OTL amp. I later on discovered the Crack and the 339, which seem to be quote a bit popular too.

            I must admit that I am still very much in the process of learning what are the characteristics in music and sound production that I like the most.

            Out of curiosity, what makes you want to sell your WA2? On your perception, how would you characterise it to the less expensive Crack and 339?

                  2399/5998. Hard to get from dealers. Sometimes they do pop up you just have to keep checking. There always are tubes on ebay but you will easily pay $100-$150 USD for a pair

    So, while searching for Crack comparison, I stumble upon this amp. And can get more or less with crack, less hassle and better warranty support than Crack. Well, I listen to a lot of genre and recently while playing with my friend amp, I found that some amp sound too distant and not suitable for aggressive song like hardcore, metal and rock. And I wonder if 339, Crack or Crack+Speedball is the bass. And I wonder if Crack only should be good for me? Thinking of pairing with my Aune T1 and maybe will upgrade in a 6 month more or less. Well, I prefer something DAC amp too because consume less space, and less socket which means tidy table for me.

    Hi, guys. Thanks for a great review and very informative thread. I’m in the process of moving from speaker setup (PSB Synchrony One) to headphones. HD650 will be my first buy, and judging from this thread I can go with either Crack or 339. Since the price of 339 is now $750 + import duties I’m wondering do I get more flexibility from 339 down the road if I want to invest in Beyer T1, LCD-X or something similar. Also, I have Micromega MyDAC left from my speaker setup, will this be on the same level as 339 with HD650?

      You’re right: Crack or 339. The 339 is better and it will give you a lot more flexibility with the headphones you mention. It won’t be the very best of course, but a lot better than the Crack. I don’t know the DAC, sorry. You’ll love the 339

    Does anyone know what the input voltage of the 339 is? My DAC (EAD DSP7000 mk iii) can output either 1V or 2V RMS at 50 ohms, and I may be imagining things but I think music sounds better (currently using an HD650) when its set at 1V RMS (more warm, less bright/edgy, deeper soundstage). I’m wondering if this has something to do with the input voltage of the 339. I’m noticing that I’m using an extremely tiny, beginning portion of the volume pot on the 339 (like barely the first 5millimeters in circumference) when my DAC is set at 2V RMS — have other folks noticed an edgier sound at such high attenuation levels?

    Only issue of using the 1V RMS output from my DAC is that the attenuation is done in the digital domain, thereby losing 1 bit from a 16bit signal, due to the PMD100 filter (HDCD standards forced non-HDCD sources to be attenuated by 6dbs). At 2 V RMS, I’m getting the full 16bit resolution from non-HDCD sources. I’m considering the idea of attaching a fixed attenuator (-12db) at the RCA inputs of the 339 and using the 2V RMS output from my DAC as a potential solution, but would love to hear your thoughts/suggestions.

        I’m beginning to also wonder if it’s just the volume pot on my unit and if it’s doing something funny at extreme attenuation levels.

    Hi, I’ve just recently been looking at stepping up my tubes because I’ve had my T90 Jubilee re-cabled have almost simultaneously come into possession of a HD-800s. Main objective being taming some of those piercing highs and aggressive treble both those headphones are known for, hence I’ve had my eye on the 339.

    Unfortunate that the most recent revision of the 339 goes for $750 instead of the original $500 ish. Living in Europe I don’t know whether or not Yuking declares the pricing lower than it actually is to help tame import taxes (25%+ on top of 750 is definitely not a pleasant experience) because of $750 I could just get a Feliks Audio Elise made in Poland (so no tax) shipped to me. The Elise is highly regarded by basically everyone that owns it and even the ones that don’t so it is tempting. Shame because I think the La Figaro is breathtakingly beautiful and I’d much rather own it over the Elise if they were to be going for the same price. Given the discrepancy I guess I’d be foolish to not opt for the Feliks Audio amp instead.

    Any experience with the Elise? If so, any thoughts on how it compares to the La Figaro?

    I have to concur with this review. I recently purchased a nearly new 339, newest version, and it is a stunningly good sounding amplifier; it even plays well with my low impedance headphones. And yes, this amp is quite powerful. I prefer rather loud playback levels and the 339 delivers with no issues.

    I like the deep richness of tone. I have always loved solid state, and still do, but in the ideal world I would have both and luckily for me I do. I’m slowly building a stockpile of nice tubes as I know that I will be keeping this OTL gem, which for me is indeed rare as I typically move gear quickly.

    First of all thanks for the verry impressive review, it is a bit old but It has been helping us a lot in that time period.

    I have been using first version of the La figaro 336C with 6SN7 and 6AS7 tube combination through Beyerdynamic T90. Amplifier was modified by changing with toroidal transformer and some small part modifications. It`s sound is very warm and powerfull, but I have a change to update it with Lafigaro 339, and also I am thiniking to buy HD800 as a second head phone, In summary, I am very needed an advice whether it is a good desicion or not to buy this 339 from my friend.

    Hello Lieven,

    Thank you for your reviews, really appreciate it!

    Need your advise please. I currently own the Herus, Duet and DT770 32ohms. I listen mostly to acoustics, jazz, pop and some EDM.
    I’am planning to get the LF339, to be my first tube amp together with HD650/DT1990 to pair with Herus.

    Which is your favourite pairing – LF399 + DT1990/HD650?
    I am thinking of Amiron as well since I have the Duet, but what I read is LF339+HD650 would sound even better.
    Seems like the LF339 could also tame down the DT1990 treble – so its easier on the ears?

    Wouldn’t the LF339+HD650 sound too warm/smooth?

    Hi Lieven,

    I’m sure you’ve heard many great sounding tube amps since the 339 was first released. Would you say the synergy is more special with the HD650 than any other amp you have heard, regardless of price?

    I ask because I’m solely looking for an amp for the HD650 and am wondering if there is anything better out there. Price, up to a point, say $2,000, isn’t an issue in this case. That’s as high as I want to go.

    Thanks

      Absolutely. The Crack and the 339. Crack for clarity and speed and 339 for smooth tube tube warmth and musicality.

      339: ef80 mesh with simple rca 6as7g. Finished.

      Keep us posted

    Hi Lieven,

    Found this review so interesting. What is your opinion on 339 compared to tube amp like Felik Audio Elise or Espressivo or Woo audio 7tp. I just got myself into OTL world, a very interesting world of combinations. So I really need your experience on those things.

    Thanks!

      Hi Jim, To me the Woo never really sounded like the Crack or 339 as OTL’s. The Feliks amps are really good though. It also depends on the type of sound you want and your budget.
      The 339 depending on the tube set used goes from neutral and analytic to smooth and romantic, it adapts really well to the tubes used and I’m not so sure the others do too.
      BTw, there’s a 339 drop on massdrop!!

        Thank you Lieven,

        I personally prefer warmth and sweet sound. I love vocal genre, it’s great to hear this amp sounds romantic. I did audition the Elise tho which I don’t know if it romantic or warmth enough to my liking. BTW I’m using HD800S and don’t expect a chance to try with 339. Expecting to buy one of these in a few days.

        Thanks!

    Somebody offered me a trade for my Schiit LYR double tube Amp, any comparisons between these two or should I keep the LYR?

      Out with the LYR, in with the 399. You’ll have a real tube amp 😉
