Review: Auris Audio HA2-SE – Perfection

Disclaimer: The Auris Audio HA2-SE was sent directly from the Auris Audio factory in Serbia and it will stay here with me. 


Auris Audio

I’m pretty sure most of you have never heard of Auris Audio before but in the High-End speaker world, the Serbian company has been on the map for several years already.

“Based on experience in design amplifiers and other electronic devices, Auris Audio’s philosophy is rooted in Superior design, natural materials and skills of making, which give us the right to claim that our products are handcrafted with soul”

Auris Audio was founded in 2013. Their mission is to fulfill the desires of the most demanding audiophiles and delight both listener’s ears and visual senses. Auris Audio puts tubes first, and how I like it.

Last May, during High End in Munich, I was having a beer at the famous beer garden at the High End show when someone came up to me, asking if I was Lieven. My Headfonia shirt probably gave that away. The guy that came up to me was Mr. Milomir Trosic, Auris Audio’s big boss. He quickly showed me a couple of pictures and asked if I would be interested in reviewing his headphone amp. We exchanged business cards and we both went our own way. After High End, things got so very busy that I didn’t get to contacting Auris to arrange a review. A few months later I discovered the Auris headphone amp at Canjam Europe in Essen and I reserved some time for it. I sat down with an original HD800 I borrowed from Jan Meier and within five minutes I knew I had to set up that review as soon as I got home.

Now, Auris Audio doesn’t only make headphone amplifiers but they have full product line-up with speaker amps, pre amps, DACs, speakers and even a full system. Auris Audio often visits the big trade shows and their setups and rooms always get a lot of attention. Check out their Twitter and Facebook accounts to keep up with what they’re doing.

The HA2-SE

The Auris headphone amplifier is called the HA2-SE and according to Auris Audio the HA2-SE represents high end stereo amplification for headphones.

The HA2-SE is a single ended amplifier and there is no balanced circuit, only RCA inputs and one 6.3mm headphone output. It has three inputs which I found very useful as one was connected to my Violectric V850 DAC, the second to my Pro-Ject Phono amp and the third to my AK380 DAP. Depending on the headphone type used (and its resistance) you can simply select the output impedance by turning a knob at the back of the unit. It has specific settings for 50, 150, 300 and 600Ohm headphones.

The HA2-SE comes with a remote control which allows you to change the volume or mute it, nothing more. The remote is rather heavy but it feels awesome. The reason? It’s carved out of a solid block of aluminum. It’s a detail, but it matters.

Tube Galore

The Auris HA2-SE of course is a tube amp and it uses four PL95 or EL95 power tubes together with an ECC82 input tube. The EL and PL95 tubes can both be used in the amplifier and you only have to flick the switch on the back as these tubes have different heater ratings. You can learn more about the EL95 (and replacements like the 6DL5) right here:

According to, the EL95 is an economic output tetrode, launched late 1955. The EL95 is designed for car radios or equipment with low power consumption and / or smaller output power demand. There are a lot of EL/PL rebrands on the market and the tubes are available for very little money

“Vacuum tubes used in Auris Audio products are subject to individual testing and internal inspection, so that only selected and match-paired tubes of the best features are incorporated in our products.”

The ECC82 input tube (which equals to a 12AU7, CV4004, CV491 etc) is a miniature nine-pin (B9A base) medium-gain dual vacuum tube. The tube is popular in vacuum tube audio as a low-noise line amplifier, driver (especially for tone stacks), and phase-inverter in vacuum tube circuits. You can learn everything about this tube type on the following two pages:

Contrary to the EL/PL95, the more famous and rare ECC82 tubes can set you back quite a lot when you want to buy them NOS.

Stock tubes & replacements

The Auris Audio HA2-SE came delivered with a “made in Yugoslavia” Ei labelled set of PL95 tubes. The replacement tubes I have in my tube stock are Siemens and Philips branded PL95 all three sets actually are identical, just rebrands.

The stock 12AU7/ECC82 tube that came with the HA2-SE was a recent Russian made Electro Harmonix (EH) tube and especially changing this one will improve the HA2-SE’s sonic quality. Not that this is a bad tube but it isn’t great either. I have a couple of 12AU7 RCA clear tops I use in several of my amps but for the HA2-SE I selected a different one.

After having listened to the overall reasonably good sounding stock tubes for several days, I switched the power tubes to a set of Mullard branded EL95 and I replaced the EH tube with a gorgeous little NOS Philips Holland made/branded ECC/CV491 tube. This combination of good NOS tubes should set you back around only $40/€40.

    WAU! GREAT! I hate you now, but I love you too…
    I´ll tell you if I buy it 😀

    • Reply February 24, 2017


      It really is an excellent amp, it even put the Violectric V281 in storage for now…

    Great review Lieven. Since you have heard both beyer amiron home with various amps and auris ha-2 se, which one – in your opinion – will sound better with amiron’s: auris or cayin? And cypher labs duet or maybe vorzuge? Thank you in advance.

    • Reply February 24, 2017


      Thanks. Of the tube amps, the Auris. Of the portable amps you will extremely pleased with either of those amps. I put them at the same level but Duet is fully balanced 😉

  • Reply February 24, 2017


    Thank you very much for the answer Lieven.
    I got my amirons recently and as much as i like them, i got a feeling i might be missing something with my current amp/dac (concero hp). Auris looks really tempting then, especially now, when I am after an upgrade 😉
    Will take a closer look at both small form amps, as often i don’t want to power up my computer – just sit back/lay down and listen to the music.
    Have a nice day, greetings, Peter

    Peter, try Feliks Audio Espressivo, I am looking that way + Beyer T90 to buy.
    This Auris is tempting, but without proper headphones is a no go. And I am not sure if I want to spend 3000 for Auris + Edition X v2.
    I really would like to, but I am the only maniac in our family…

  • Reply February 24, 2017


    Thank you for the tip Tibor, will take a closer look at FA Espressivo.
    And i fully understand your dilema – i’m a gearhead too 😉

        Waiting for it.

  • Reply February 27, 2017


    Great review and waited for a long long time. Thanks Lieven.
    I’m really interest on ha2-se now.
    If compare it to Trafomatic the Head2, how do you think?
    These two also my target amp.

    • Reply March 25, 2017


      Also interested in that.

    Great review, congratulations. IEMs JH Layla costs the same as Auris HA2-SE + HifiMan Edition X V2. Can you briefly share your thoughts about sound quality of each, stage, details, smoothness, bass, … What option do you prefer in case of both paired with AK380 hi-res files? Thanks.

  • Reply March 12, 2017


    Thanks for the review Lieven. I going to buy blind based on your review since there is no local distributor for the amp, but just wondering you figure which is the best DAC for the tube amp?

    • Reply March 13, 2017


      Something clean, detailed and to the analytical side. Think ess sabre chips

    • Reply March 13, 2017


      And you won’t regret it. It is sublime

    Hello Lieven,
    A real love story …
    Woo Audio WA22 or this one? What do you think?

    • Reply March 15, 2017


      Both excellent. Need balanced? In Europe the choice is easy

  • Reply March 16, 2017

    Michel I

    I like balanced, but I don’t really need it. What is your easy choice in Europe?

    • Reply March 16, 2017


      When buying from woo you have expensive shipping from the US. Shipping it back in case of issues blows and you will have to pay quite some Moortown taxes. On top of that the amps aren’t CE certified BUT they are great. Auris comes from Serbia but is practically Europe. It arrived in 3 days with hardly any taxes

  • Reply August 26, 2017



    Does it make sense to use a herus+ dac with this amp, or will it sort of downgrade its potential?
    If i can save on buying a more expensive dac…


  • Reply August 27, 2017


    Well the Herus is very good in its price range, but a better dedicated full sized DAC will improve the end result even more. I wouldn’t call it a downgrade, rather a limitation

  • Reply August 30, 2017


    Thanks for the answer, would you say about the same using the Chord mojo DAC as it is praise quite a bit…?
    Again thanks for your insight!

  • Reply August 30, 2017


    Actually, while Mojo is good, I’d say the same as I did for the Herus. Now with Hugo 2, there’s a real step up in performance

    Hello, I just read their test on the Auris HA 2 SE Amp. Very nicely described. I would like to test it myself. I use the HE1000 V2. At the moment I use the Phonitor-e as an amplifier. As a DAC I use the Metrum Adagio. My question to them: Can the Auris be better than the Phonito-e?
    Excuse my english, I use the translator.

    Greetings from Saabrücken, Marc

    • Reply October 27, 2017


      I’m not too familiar with the Phonitor-E, so it’s hard to comment on that. But different it will surely be. 🙂

    There is a single man behind great products, if not the best in audio world (i can say that because he’s my best-man, and friend since our 10, when we started to learn electronics. He, continued to develop high-end audio amplifiers, mainly based on tubes. Lately, he ended up with CD player based on tubes, amplifier as well and Digital system loudspeakers active crossover (for 6 or twelve speakers?). When we were young, we started to deal with DIY electronics, from the collected schema’s, but we were learning so fast that we developed our own amplifiers, remote controlled servo’s for boats,airplanes, DC power supplies etc. I enriched my perspective with 5 in a row, different Cassette decks, hand made by me (perhaps, only one in the World), and he continued as I mentioned before. Later, in early 90’s, I gave up of electronics, and moved on into the IT field. He is great engineer (we’re both self-educated), and I am positive that he deserve greater attention from the wider audience. Here is his blog (unfortunately, on Serbian language, but it can be easily translated through Google Translate). Cheers.

    Hi, I see in a picture the new Cayin headphone amp. Big price difference but how would you compare these two

    • Reply March 29, 2018


      The Cayin amp sounds warmer and has more body. it’s a really romantic sounding, smooth tube amp. Unfortunately with a higher noise floor as well. But it’s really great with the right headphone. The auris is the best all-rounder though

  • Reply July 14, 2018


    Hi, I just bought this amp a few days ago and everytime I switch it on, there is a continuous noise on the background. The noise is even higher when I put the impedance on 600 ohms to drive my Beyer T1.2. It decreases when I lower the impedance.

    I tried with other headphones but still the same. It’s more audible with the Beyer T1.2.

    It’s really annoying when listening to music, especially when the song includes a silence part.

    Any help? Or is my unit defective?


    • Reply August 10, 2018


      tube amps are pretty sensitive to noise..noise can come in the form of a wifi access point too near to the amp or even dirty power coming from the mains. Try adding a power conditioner and if the access point is near, move it further..

      Good luck!
