Burson Audio – Conductor 3 Reference – Headphone Amp / Pre-amp / DAC
I have had the good fortune to spend some time with Burson’s new Conductor 3 Headphone Amp. I was excited to hear the amp having previously spent time with, and absolutely loving their ‘Swing’ Pre-amp (Review HERE)
What is it and what does it do ? – From the Website:
The Best DAC / Headphone Amp / Preamp
Being the best of its time. This has been the sole design goal of each Burson Conductor since 2007. The C3 Reference took 3 years to built and it leaves the competition for dust.
Advanced Digital
The SABRE32 / ESS9038Q2M DAC and XMOS USB receiver chips are the most advanced and expensive in the industry. There are two ESS9038 DAC chips in our C3 Reference and its USB receiver comes with customised driver by Thesycon, Germany. The result is unsurpassed processing power, perfectly playing back DSD512 and 38bit/786khz audio. The C3 Reference also features a Bluetooth 5.0 receiver Qualcomm/CSR8675 [+] with aptX HD audio codec. It pushes Bluetooth playback beyond CD quality and ease of use to the highest level.
Max Power X 5
Max Current Power Supply (MCPS) [+] raises voltage frequency from 50Hz to 170kHz, pushing noise beyond human hearing. Its low impedance ensures abundant and instant energy for output transistors. The C3 Reference uses 5 sets of MCPS: Which means, Display/Functionality, DAC, analouge left and analouge right are all separately powered.
The Cool Case
Let’s face it, most audio equipment cases are ugly and impractical. They usually have visible screws everywhere, sharp corners and boring colours. Class-A amplifiers even have finger cutting heat-sinks! They diminish the aesthetic of any living space especially modern desktops where every other electronic is slick and refined.
Made from high-density aluminium and electroplated to space-grey. The Cool Case [+] has only 4 visible screws under its belly. It is also a unified heat-sink that is 300% more efficient than previous Conductors. It is audio jewellery at its finest and It looks and plays very cool.
Smooth Control
The all-new OLED screen and interface program deliver a calming and intuitive user experience. Its machined solid aluminium knob offers the fines control and feels luxurious.
The Review
[Disclaimer] - I have no affiliation with Burson and was loaned the amp for the duration of the review period only
As with my previous review on the Swing I will be focussing on the sound itself. There are other excellent reviews that cover the technical details especially by Head-fi member Darku
Equipment used:
For my source I used iBasso DX200 Line out and Coaxial output.
For headphones – Sennheiser HD 540 Reference 1 - 600 ohm - Sony MDR-CD900ST

Just briefly to touch on the general operation of the BAC3. I had no problems working out how everything worked as BAC3 has a huge display, four buttons and a smooth and quick dial to make selections with. Each selectable item is represented by a large icon – simply moving the dial and pushing it in selects the item, turning the dial again once selected gives the different options and pushing in the dial again selects your new choice. Easy!
The Sound
Sound stage / Imaging / Layers
This is one area that immediately stands out as nothing short of extraordinary. Its difficult to fully appreciate just how profound music can sound until you experience it directly with an amp of this calibre. The one thing I noticed at first was how the BAC3 doesn’t immediately strike you as having an ‘excessively’ huge soundstage but this a real boon as it shows how great the imaging and separation is.
Sometimes companies use gimmicks to make areas such as soundstage and bass sound bigger than they actually are which initially can give a certain ‘wow’ factor but this is not realistic or true to the recording and so rarely stands the test of time.
The BAC3 however, is the real deal. Due to the three years of research and design, the best possible components used including the worlds most advanced DAC - the ESS Sabre 9038; the BAC3 gives a truthful representation that more than lives up to its Reference classification
The imaging in particular is exceptional. The BAC3 somehow manages to give each instrument its own unique place in the mix in such a way that you can focus in on and not only enjoy all the subtle and micro details, but also the special characteristics of each instrument.
With the track ‘Aja’ from Steely Dan you clearly hear the wood of the drum sticks hitting the cymbals both in the background, to the left and then the right and despite all the other instruments; the crash and full decay of the cymbals.
This level of detail and imaging is a clear indication of a great reference amp and really is the stuff of dreams as far as Audiophile listening goes
The depth and positioning of the instruments is also beautifully presented, again subtle but there to be enjoyed by the discerning Audiophile. The way instruments are separated is also presented in a layered manner, so not only do you have everything in its own position both from left, right and centre but you can hear instruments both in front of and behind each other in the space before you! Something I had as yet not had the pleasure to experience…until now
The instruments are also presented with firm authority. This is not as easy term to define. An analogy to try to illustrate is - like the difference between a timid and nervous singer and a singer on top of their game – in the sense that each note feels full, rich and supremely confident!
Highs / Mids / Low End
Sometimes I think that if you can hear certin characteristics with the highs then something is not quite tuned as well as it should or perhaps could be. With the BAC3 everything is extremely well balanced. You rarely hear anything other than the music. When you do hear the high frequencies it tends to come from the clear but brassy crash of a cymbal or the ‘zing’ of acoustic guitar strings – they always seem to be a part off the whole rather than trying too hard.
Again, with the Mids the vocals always sound clear as day, have a natural timbre but are so well balanced with everything else you tend to just get lost in the emotion of the song as a whole. Male and female vocals just sound ‘right’ . . . as they should coming from a Reference Amp.
The Low end is both deep, rich and very well textured, neither dominating the mix or surrendering any of its qualities to the mids. Listening to the rolling drum kit intros of Joe Walsh ‘Country Fair’ SACD and to the later rhythm drum / percussion sections of the song shows how good the ESS Sabre 9038 really is. The tonality of the drum hits are perfect, varied and textured whilst still maintaining the brass crash and full decays of the cymbals.
Where as with the Swing pre-amp I sometimes found this area could be a tiny bit weak with the BAC3 Im clearly hearing everything is now as near to perfect as I could wish for. Its very impressive how they have upped the game with the BAC3 in subtle but very meaningful ways
In fact the quality of the BAC3 has made writing a review particularly difficult in the sense that there is nothing I can find wrong with it. But here is the most important point that I would to make about the BAC3
1. It is a Reference Class Amp and performs perfectly in this role. I can reference any music I own, from DSD to Hi Res Flac to CD. I can listen and appreciate that the information the BAC3 is giving me I can use as a reference point to how the audio actually sounds and to measure other amps too.
2. The DAC chip is of the highest possible pedigree. The ESS Sabre 9038DQ2M is one ofm if not the best out there. I must confess to always liking the Sabre chips. They are not trying to be ‘clever’ or offer a special type of sound, they just want to give you the raw audio you have given them and give in return an honest, yet powerful and detailed sound. When these chips are tuned/implemented to perfection you find yourself with a powerful animal that can roar but that can also offer the sweetest quietest emotions when needed.
With the Swing Pre-amp, when initially listening with the V5 Opamps installed I found a nice neutral, soft, clean, yet analytical sound that had a defined Audiophile level of detail. Moving over to the upgraded V6 Opamps I found a more energetic powerful sound that seemed like going from a tight well executed orchestral piece to a top rock band. Both Opamps offered their own unique sound that was enjoyable for different genres. I enjoyed each one in its own way but felt they each offered at times something the other did not depending on what I was listening to
With the BAC3 I was very pleased to find they had somehow managed to combine the best of each of the Opamps characters and on top of that create an even more mature, reference level of quality. The detailed clear and almost delicate way each note is handled, reminiscent of the V5, coupled with a fuller and slightly more energetic sound, like the V6, negated the slightly negative aspects of the characteristics of the different Opamps that I had picked up on before. That they have managed to do this is a testament to the skill of the team of Burson! Whilst these improvements in one sense are quite subtle, at this level of quality even the smallest niggle can interfere with ones full enjoyment and absorption into the music.
In summary, Team Burson have taken the finest qualities of their Opamps, the ESS Sabre Dac Chips and along with their MCPS power supply and newly designed chassis have produced a market leading Reference Amp
Thank you to Burson for the opportunity to spend some time with this excellent Amp

Thank you to Burson for the opportunity to spend some time with this excellent Amp
I was looking at hybrids such as the Project Ember II and smaller powerhouses like the Schiit Asgard 3 (which may yet be a good match), but your review has swayed me to look a bit further up the quality scale, AND it has a DAC built in!
Nice!
