Less Blockage, More Music: Burson Soloist

Burson has always been an advocate of discrete amps. As a reviewer, I don’t always agree that discrete is superior to op-amps or chip-amps. While discrete designs are usually better in instrument articulation and low bass extension, they don’t have the coherence that chip-based amps have which. Burson argued that while an op-amp based amplifier would ultimately yield a shorter signal path (which is good), their Soloist design actually wins in terms of components count (21 components in the signal path vs 50+ in a typical op-amp). Having listened to the Soloist, I can confirm that they have indeed succeeded in getting that coherence factor right with the discrete-based Soloist. I can hear the music plays together better, whereas with the HA-160D, the superior instrument articulation tends to break the recordings apart to many different pieces.

Sometimes in the middle of this review period, I asked Burson to why I hadn’t notice any burn-in difference throughout the time I spent with the amp. Usually one of the things that you can expect with burning in your amp is improvement on bass texture (Though I don’t believe, nor have I encountered any case where an amp requires hundreds-hours of burn in to finally mature). Apparently Burson have took the time to run the amplifier that it already had enough burn in time by the time they sent it to me. Ah, so that explains it.

I left the Soloist on the local Jaben store for a few days, and the impressions so far is that we all agree that the Soloist is the best amplifier that we’ve heard the HE-6 with so far. The application however is not limited to the HE-6, as the tonality, the power, and the musicality of the Soloist makes it the best sounding solid state amplifier I’ve listened to.

 

Gear used for review:

Burson Soloist, Burson HA-160D, RSA Dark Star, HRT iStreamer, KingRex UPower, Hifiman HE-6 and HE-500, Audez’e LCD-2, Sennheiser

Three inputs, three gain settings, selectable from the relay based soft touch button. This sets the benchmark in terms of headphone amplifier user friendliness.
The back side reveals three sets of inputs and a pre-out.
The whole amp is very simple. The lower half, along with the big round transformer case represents the power supply. The upper half represents the amplifier section.
Very simple amplifier section.
Power supply section.
Low noise transformer = zero hum on the headphone out.
Front view, naked.
You can see from this angle that the transistors are mounted to the bottom plate of the amp. Hence the whole thick aluminum enclosure serves as a heatsink, and the amplifier is always warm to touch.

    Mike, how would you compare this with the HA-160?

    • Trent_D

      I think the answers you seek lie in this review. With a keen eye, look it over again. Page 2 has some good stuff. Just remember, the HA-160D equals the HA-160.

        Thanks, Trent.

          Hi Mike, with Alessandro MS-PRO and W3000ANV, which one, the soloist and the HA-160, will be your better recommendation?

          • http://www.headfonia.com Mike

            I like the MS-Pro with the Soloist better than the HA-160.

            For the W3000ANV I like it with the Soloist, but never compared it to the HA-160.

            The nice thing about the MS-Pro + Soloist combo is that it add bass body and relaxes the treble. Pretty much the same with the HE-6.

    Great review, Mike! I must say though, I think the Burson logo looks good even without the original logo we all know. It kind of makes it live to its name in terms of originality. Anywho, great review again, Mike! :)

    Hi Mike, How does the Soloist pair with the HD800?

    • http://www.headfonia.com Mike

      I didn’t try it with the HD800 to be honest. I tend to like the 800 with tubes.

    Hi Mike,
    the Soloist and 160DS, Which one is better with Denon D7000?

    • http://www.headfonia.com Mike

      Terry,
      I didn’t check it with the Denon D7000. Personally I like the Soloist far more than the 160 series. So I’ll probably like it better with the Denon as well.

  • johthor

    Thanks Mike for another excellent review. I have owned the 160DS for some time now and the only HP I own that it does not seem to have enough power for is my HE 500. I have to pretty well max out the volume with this HP and I am concerned that I am not getting the best out of this oustanding HP. In your review you mentioned that the new Soloist works well with the HE500. Would you be able to elaborate as to how the Soloist manages this. Thanks Mike and I really like the review

    • http://www.headfonia.com Mike

      With the HE-500, the Burson amp on medium gain, I’m listening at about 12 O’clock, while at 1-2 O’clock it’s getting too loud for my ears.

      • johthor

        Thanks for the reply Mike. I must be missing something here. How do I adjust the gain on the Burson 160DS?

        • http://www.headfonia.com Mike

          You can’t. The DS only comes with one gain setting.

          • johthor

            Well that sucks because otherwise the DS160 is a very nice DAC/AMP combo. I will not be selling it as it powers everything else I have. It is actually worth keeping for my HD650s alone. Could I get a recommendation from you for a combo DAC/AMP for the HE 500 and for a future HE 6. Budget $500 to $1000. Thank you in advance

            • http://www.headfonia.com Mike

              Nothing that I know of at the moment.

  • http://www.facebook.com/songmic Song Kyung-han

    Mike, how much does the Soloist sound open, airy, and fresh compared to its competitors? What can you tell me about its clarity, and bass quality? When you said “the best sounding solid-state amplifier you’ve listened to” you mean you personally prefer this amp to the likes of RSA Dark Star?

    More importantly, I’d like to know how the Burson Soloist performs with low impedance closed dynamic headphones, such as those from Audio-Technica. As you know I’ve recently bought myself a Fostex TH900, and now I’m looking for a decent solid-state amp to drive it. The Soloist is one of the amps I’m considering to buy, and I have high expectations for it, but it’s the headphone matching with the proper headphone amp that’s really important.

    • http://www.headfonia.com Mike

      Yes I truly love the Soloist more than any other solid states I’ve owned or had auditioned. The Dark Star I still have, but I think the Soloist, while not sounding as spacious as the Dark Star, offered more for me in that I find it to be more musical due to the thicker mids and lows. The sound is not as clean in the Soloist, but again it’s not always about pure technicalities superiority.

      I enjoyed the Soloist with the W3000ANV and W5000 and that’s the amp that I use the most to do the Audio technica review.

      I’m not so sure about the Fostex TH900 though.

      • http://www.facebook.com/songmic Song Kyung-han

        Thanks for your input. I’m selling my current Schiit Lyr (not quite suitable for driving sensitive TH900) and ordering the Soloist. I’ll share my impression with it once it’s in my hands. But so far everyone I’ve asked said nothing but positive things about it, especially with low impedance dynamic headphones.

        • http://www.headfonia.com Mike

          Yes I’m listening to the Burson with Sony’s Z1000 at the moment. Superb combination.

          • http://www.facebook.com/songmic Song Kyung-han

            One more question… what is the preferable gain setting for low-impedance, high-sensitive headphones? Does the gain setting matter with such specifications, at all?

            • http://www.headfonia.com Mike

              You can try either the low or the medium gain. You’ll get less volume control range with medium gain, but I think the sound is more forward and more fun at medium gain, while at low gain it’s more laid-back but with a lower noise floor.

        • http://www.headfonia.com Mike

          Zero hiss with the Z1000 on Burson’s low gain, and I’m listening at about 12 O’clock with the Z1000.

    Hi Mike,
    Which DAC would you recommend with the Soloist?
    Thanks,
    Mate

    • http://www.headfonia.com Mike

      Mate,
      I really don’t think it has to be one particular DAC, but the ones I’ve been using with it with good results are: HRT HeadStreamer, KingRex UD384, and Matrix M-Stage DAC.

      • http://www.facebook.com/people/Mate-Mayer/1335311034 Mate Mayer

        Thanks Mike! How about pairing it with Burson’s own DAC?
        Mate

        • http://www.headfonia.com Mike

          I actually haven’t tried that combo, Mate.

    Hi Mike, after trying the HE-500 on the Soloist, will you think that this is a better match compare to HE-500 with Graham Slee Solo?

    • http://www.headfonia.com Mike

      The signature is different, Victor. The Solo is smoother and mellower, the Soloist more PRaT and bass, but less clean than the Solo.

  • http://www.facebook.com/profile.php?id=692862021 Nick Tam

    Seeing how you haven’t done an exact comparison, down memory lane, what are the sound characteristics that stand out between the V200 and Soloist, or even the Solo SRGII? You’ve mentioned their synergy driving the Hifimans, so was thinking about the ideal amp driving the Hifimans. Thx Mike

    • http://www.headfonia.com Mike

      Nick,
      The V200 I still haven’t listened to.

      Simply put, Solo SRG II is smoother and slower paced. Burson is more lively, stronger bass, more energy.

  • Alexander Ivanov

    Did you try this amp with Sennheiser 800 / 650 / 600?

    • http://www.headfonia.com Mike

      Yes.
      I tried it with the Senns and they were good, but not particularly stellar. Especially the HD800 I think is best with tubes.

  • http://www.facebook.com/songmic Song Kyung-han

    I wonder if you are having the same issue with your Soloist. I just noticed it pretty recently, and wonder if this is normal. Now I’m usually listening to it at low or medium gain depending on what I listen to. However, other than the sonic differences between gains you’ve mentioned in a previous article (laid-back/forward, clearer, soundstage, etc.), I also notice a volume difference between the two channels. When I switch from low to medium gain while listening to music, I can definitely feel that the volume increase in the right channel was greater than that of the left channel. In other words, at low gain the music sounds relatively tilted to the left, while at medium gain it sounds more tilted to the right. Could you try this yourself and tell me if you notice the same thing?

    • http://www.headfonia.com Mike

      Hi,
      No such problem with my Soloist.

      Can you try this though: unplug your headphones, and rotate the volume knob clockwise and counter clockwise really fast, about 10-20 times. Just checking if it’s just the dirty contacts on the volume attenuator.

      Again make sure there is no headphone connected.

  • Shahrose

    Hey Mike, I’m wondering what you think of the Soloist vs the Arete + Volcano in terms of SQ.

    • http://www.headfonia.com Mike

      Hi,
      I don’t have both here at the moment, but from memory I think the Arete + Volcano is more spacious.

  • Horatiu Mihalache

    Hi Mike,

    I asked the same question in the Lehmann Black Cube Linear preview, I hope you don’t mind I repeat it hear. How does the Soloist compare with the BCL? Especially when paired with HD 650 or LCD-3 (LCD-2?).

    Thank you!

    • http://www.headfonia.com Mike

      Sorry missed your question!

      The Lehmann is very clean, precise, a little sterile, more laid back.
      The Burson is more organic, more analog, fuller mid and low end body, more grainy, stronger bass punch, more forward.

      With high quality digital classical and Jazz recordings I think the Lehman is very nice to listen to. Pop/Rock mainstream stuff, I’d go for the Burson.

      • Horatiu Mihalache

        Thank you, Mike, I appreciate your efforts. I think I might go for the Soloist, though I found an used BCL at a very good price.

        • http://www.headfonia.com Mike

          You’re welcome. Next time I’m not answering your question again, please repost. ;)

          It’s easy for me to miss questions.

  • Elroy

    I like what I’ve read about the Soloist and am considering buying it but wonder what would be a good DAC to pair with it. I ask because I have read that the Conductor is outstanding but the DAC is not quite equal. Am liking what I have read about the Rein X-DAC. This combo will more than likely be used with Senn. HD700′s or Audeze LCD 2′s. Also, it will be used to listen to a variety of generes ripped at lossless. Any other suggestions as to DAC would be greatly appreciated, looking to keep the entire setup in the $3000 range.

    • Trent_D

      Does that budget include the headphones? I thought I should mention that if you don’t need the preamp function, Burson just released the Soloist SL, which is the same amp, just smaller and $400 less.

      • Elroy

        It was to include the headphones. Regarding the preamp function and to quote my 4 year old nephew “I do not know!” Do I need the preamp function, what does it do for me, or what else would do that function for me. It gets more complicated, in searching for info on the Rein and Burson combo I am now leaning towards the Violectric V200 & V800 combo. Any thoughts?

        • http://www.headfonia.com Mike

          I really have no experience with the the Rein units and how they compare to the Burson.

          There are a lot of DACs to recommend, perhaps you can start by browsing the Source page?

  • aras87

    Hi Mike,
    Can you compare soloist and centrance dacmini? Thanks!
