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'm making the switch to a tubed linestage and it looks like I will be going with the Zanden 5000 mkIV as my DAC. I really love the way it handles vocals in my system.
Right now I'm just waiting for the Altmann JISCO to add to the Zanden.
Exlibris, Does this mean you are going to let go the Altmann DAC? Why not go with Zanden tubed linestage? (Synergy). I am glad u provided inputs. That is one up for Zanden in my book, As I continue to struggle with my own Transport DAC upgrade, this kind of gives me a good valid data point.
I'm not sure what I'll do with the Attraction. I still haven't even tried it as a DAC for 24/96 (and higher) formats.

I'm sure the Zanden linestage is excellent and if Zanden wanted to send me one to demo I would welcome the opportunity! :-)

Right now I'm trying the Aesthetix Callisto linestage and I'll be trying the Atma-Sphere MP-1 as well. Who knows, maybe my system will sound better with the Attraction in place once I insert the MP-1?

I won't go into details about the Callisto because this thread is about DACs. I will say, however, that I've listed my Blowtorch for sale.
Interesting thread Exlibris, I had a similar experience with a tubed Audio Logic Dac and a Museatex Bitstream Dac.
The Bitstream sounds the way you describe the Altmann Dac, I kept it and sold the Audio Logic.
A few years ago I posted a thread on the Altmann Tube-O-Lator kit, a laquer based substance used to coat transistors and chips for a warmer, tube-like, natural sound, but it didn't get too much attention !
Is the Altmann Dac sold direct only ?
Yes, the Altmann DAC is only sold direct.

I'm also interested in his ideas on acoustics and the effect of laquer on wood in rooms.
