Reference DACS: An overall perspective


There has been many threads the last few months regarding the sonic signature of some of the highest regarded reference DACS (Dcs,Meitner,Ensemble,Audio Note,Zanden,Reimyo,Accustic Arts) here on the GON. I have been very fortunate to audtion many of these wonderful pieces in my home or friend's systems. I wanted to share, in a systematic way, my impressions/opinions with you GON members for a two reasons: 1)That my experiences might be helpful to fellow members interested in audtioning these DACS. 2)Starting an interesting discussion regarding the different "sonic flavors" of these reference digital front ends. I totally agree with the statement, "if you have not heard it you don't have an opinion". Therefore, I have no comments regarding DACS from Weiss,Goldmund,Audio Aero and Burmester because I have never had the pleasure of audtioning them. I would love to hear from members who have and share their experiences with us. My overall impression is that these DACS(Dcs,Meitner,Ensemble,Audio Note,Zanden,Reimyo,Accustic Arts) can be grouped into two molar categories regarding their overall sonic signature. By the way, all of them can throw a large/deep soundstage with excellent layering in the acoustic space with "air" around individual players on that stage. However, than they start to part company into two major categories. Category #1) These DACS "flavors" revolve around pristine clarity, fine sharp details,speed,very extended top/bottom frequencies,and great PRAT. These DACS never sound "etched" or "in your face" but are more "upfront" then "layed back" in their presentation. The DACS, to my ear's, that go into this bracket are Dcs,Ensemble,Meitner. My personnal favorite in this group is the Ensemble, which I owned for two years. These DACS remind me of the sonic signature of speakers such as Wilson,Thiel,Dynaudio, Focal/JM Labs. Category #2) These DACS "flavors" revolve around a "musical/organic" sense, natural timbres,and an easy flowing liquidity. Their "less forward" presentation my give the impression of less detail, but I think in this case its an illusion fostered by their more relaxed/organic manner. The DACS, to my ear's, that go into this bracket are Audio Note,Zanden,Reimyo,Accustic Arts. I did find that the tube DACS did not have the top/bottom frequency extenstion and PRAT of the SS DACS in this bracket. For me, the Accustic Arts DAC1-MK3 gave me the best of both categories, therefore it is now the resident DAC in my system. These DACS remind me of the sonic signature of speakers such as Magnepan,Von Schweikert,Sonus Faber. Well, it's all just my opinion regarding these digital pieces, but I hope this post was at least informative/somewhat interesting and would lend itself to other GON members sharing their impressions, not about what DAC is the "BEST" in the world, but your personnal taste and synergy with your system.

I would like to know which brand powercords are best match
with Accustic Arts transport and converters ?
Thanks in advance
Teajay thanks for your input, I like harmonix powercord too
Kimber pk14 is also fine contender, strange to say but I prefer Harmonix HS 102 xlr digital cable over Stealth sextet
in my setup too.
I have listened Esoteric combo in my friend system many times
I had Chord Dac64 paired AA Drive1 MK1 transport then I had
Reimyo DAP777 dac paired AA Drive 1 MKII transport and currently I have AA Dac MK4 with AA transport after I purchased AA dac mk4 I bought AA preamplifier (thanks to Teajay recommendation) this preamp together with my tube amp
(Leben CS660) brought the sound into reference level standard
I mean digital and low voltage analog signal passed through all AA equipments (AA transport,dac,and preamp)maybe this synergy is explaining what and how the manufacturer understand from sound and music (if I were not a tube guy and very happy with Leben amp,I would try AA power amp too)
After reaching top level digital front ends(AA,Esoteric,AN,Zanden,EMM,etc..)I believe tube types(As Tejay refers)interconnects(digital or analog)powercords even
speaker cables and speakers make huge differencies and effects in comparison those brands, I mean,ie,if someone prefers Esoteric over AA on the bass region with his interconnects or other equipments(pc,tube rolling etc..) he might change his mind with another brand equipments if he try IMHO
George,
It is a good question indeed I will be happy to learn his comments on dacs alone
too. However this topic is reference dacs titled,comments were presented mostly on same brand transport dac combos,and IMO Teac transports(which Esoteric uses)are clearer,punchier with more bass weight vs Philips transports
(which AA uses)are smoother more musical and more laid back.
The mentioned differencies between AA and Esoteric combos may come from
their transport sound character.
Funny to say but I tried many powercords for AA transport to be able to get clearer punchier sound with more bold and could not succeed to find one then I made a diy powercord using SOLID CORE 3x1,5 mm with rubber outer
shield only terminated with Frutech gold AC plug and Wattage IEC plug and
my AA transport has all sonic capacity I need whereas many different brand powercords worked very well with AA dac
Teajay, I know very well Shuguang 12AX7 tubes (I am still using them in my Unison Research tube amp)which AA used in Tube Dac,they have syrupy and blury low mids and upper bass as Branimir indicated. I guess you got better result replacing the stock tubes.
I would purchase Tube Dac if I have not tubes in my system already but did not
want to struggle with many those small tubes already I have 5
Branimir,
I thank you for your detailed comparison AA and Esoteric transport/dacs
Could you please write your observations about human voice(female especially)
violin and other string instruments comparing them if you have listened such instruments playing on both of them.
Thanks in advance
Branimir,
Thanks a lot for your test report,though I have AA dac mk4 not tube dac and
only listen Esoteric combo in my friend s system (not in my setup doing A/B tests) I have similar observations mostly with yours
Esoteric is more powerful (more upfront)clearer (not having tube noises vs tube dac and better signal to noise ratio vs dac mk4) a bit better bass definition but dac mk4 is not syrupy or slow and I think it is a little more musical for long term listening,and as all we know digital interconnects and powercords make dramatic effects on transport and dacs
I again thank you for your detailed comparison
