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.

Esoteric just introduced replacment for DV50s in Japan-two models! SA-60 and DV-60, SA-60 is SACD/CD player only while DV-60 is universal player. More details soon!
Both are expected to hit stores in USA and Europe early autumn 2006.
Another DAC to add to the Reference list going here: The Altmann Attraction DAC. Link below:

Probably the most well balanced, organic presentation of redbook I have heard.
Pardales, what DACs have you compared the Altmann Attraction directly against? The page you kindly pointed us to is certainly interesting, yet statements like the following concern me:

"Like the BYOB amplifier, the complete electronic assembly of the Attraction DAC is vibrationally optimized, as the pcb is flat-press-mounted on a specially
treated spruce-board. This construction is time-consuming during manufacture, but improves sound quality, as all components are mechanically coupled to
a musical sound board."

Sound boards are part of the mechanical sound amplifier -- also called resonator -- found in most acoustic string instruments. They operate on mechanical vibrations ranging roughly from 20Hz to 20Khz, depending on size etc. . . I am not aware the operation of precision electronic is improved by having the chips tossed about on a surface tuned to vibrate at audible frequencies. If the Altmann design truly works, it may be one of those cases where a device excels in spite of its engineering principles, rather than because of them.

Not quite. The DV-60 is available in the US now.
Guidocorona: I am certainly not one to get into the technical aspects of these things -- I am just not qualified -- Charles Altmann, the designer, has a whole page on the site devoted to vibration that would be worth reading if you are interested. If you think this little spruce board vibrates (which just about everything does), imagine how much a large metal box (what surrounds most stereo components) vibrates in comparison. Food for thought.....

DAC's owned by me in the last 18 months:

Dodson 217 MK II D
Dodson 218
Audio Aero Prima MK II SE
Benchmark DAC 1
Apogee Mini USB

The Attraction DAC is the most pleasing to my ear thus far.
