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.

Teajay, while this topic has run it's course, it helped me arrive at a sound that surpasses my wildest expectations. I have heard a wide number of Audio Note systems. My own system's DACs have been Audio Note for years.

I did not care for the Audio Note transports. I heard spacial distortion that displeased me. I used PSA Lambda successfully for a couple years. The combination was very good. It was not the last word on detail, or frequency extension, as, you pointed out.

For my DAC, I stuck with my Audio Note while adding cutting edge diodes. these diodes pass on the full array of digital information, hidden by the usual AN diodes. I can't remember if I read it here or somewhere else, anyway, I had the pleasure of finding the 47 Lab site. Just reading their philosophy, I became a devoted advocate for their transports. The 47 lab DAC, in conjunction with their transport, was lovely, true toned, an is the ultimate in musicality IMO.

On the other hand, the 47 Lab transport used with my Audio Note * it became a musical event producing a sound I had not dreamed possible. It gives full expression including PRAT, ultimate extension, decay to black, alarming dynamics, and a spritely micro-dynamic play that is most satisfying in piano solos.

bugles squeal, violins sweetly sear, cymbals crash, clang, and ring, Giant drum skins hit have that soft whack, a quick ripple crack, then a deep chested boom.

Singers are presented forward and are so lovingly living. The tiniest inflection can be heard, but never does detail trump realism. The highs are exquisitely fine. Bass is fully expressed, remaining a musical part of a musical whole in harmony.

It goes one important step further, though. The music as a wonderful flow. Harmonies, positional seating, roll off in a way only the best Vinyl systems can approach.

My system eschews all oversampling, upsampling, and filters. They all sound contrived on my system. I have not heard some of the highest brands you love. I would like to give them a try, though I hold little hope for them.

I have found every components must be designed to do the least amount of harm to the music signal. Every time the signal is switched, filtered, made to jump hoops, the more the signal looses bits and pieces.

The world’s first DAC to feature a 32bit/384kHz conversion technique, the DAC I-MK3 utilizes an Accustic Arts exclusive: an 8-times oversampling, 119dB dynamic, premium quality parallel multiplier with 32-bit accumulator that boosts incoming, 16-bit signal beyond 24-bit, to 32-bit resolution before conversion.

Each statement - pure joy!
Hahaha, an 8-times oversampling...
Very warm analogue sound.
Hi Rokka,

I had the AA DAC-1MK3 and wrote a review of it here on the GON. It was quite good, however, it is not as musical and as natural sounding as the AA Tube Hybrid reference DAC that still is my reference in my system.
Muralman1, "Every time the signal is switched, filtered, made to jump hoops, the more the signal looses bits and pieces." Very interesting comment comming from you, after you have so frequently posted so many positive comments re: your prefered switching amplifier.
Just telling it like it is. I make no bones about how I was lucky in most instances at the start. Then, it occurred to me, the winning path for increasing simplicity of the music's path was obvious.
