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.

Has anyone compared the latest DACs with the Levinson 30.6 and 31.5 combo? How close is it to the SOTA? I'm interested in Redbook only. I currently own a 360s/31.5 and have seen some info on this thread concerning the 360s DAC, but not the 30.6 which is a different beast. I know it would not have the latest chips, but the power supply looks superior to many efforts, having a dedicated power supply for the left, right channels, and digital. These things don't last long on Audiogon so there must be a demand especially at $6500.? I'd sure like some info.
Thanks,

Banimir, thank you for the info and also the link...it was a good read, though extraordinarly long-winded. The jitter specs mentioned regarding the XO-3 and UX-3 may contribute to the perceived sense of the XO-3 being slightly better? I wish he would have explained why the UX-3 had higher jitter...I wonder how the video electronics could contribute to higher jitter, everything else the same? Nevertheless, it's still good info.

I did enjoy the addition of Jeff Kalt's thoughts on "upsampling" vs. "oversampling" and his preference for synchronous over/upsampling vs. asynchronous. Thanks for the link!!

Branimir, that was an amusing and fair article. My own observations on a couple of X-01 players under control of a G0s clock closely match Babybears inconclusive findings. Theory is that these external clocks have probably more impact on multibox units such as P01/D01. What's your own finding Branimir?

I especially enjoyed the article's comment in the conclusion section:

"After all, if the razzle-dazzle technology implemented in the reclocker operates with such
subtlety on the X-03, it means that the latter is scarily good on its very own terms."
In a test with the g25 clock with X03, no sound improvement justified the purchase so it went back to the dealer.
The big components need the g0, the g25 is not ....but again you don't have 100% success on all your products.
Guido, Jordan and rest-glad you like the article!

Guido, effect of G-0s is truly as you said more apparent on combo's like P-01/D-01 or P-03/D-03...
I first listen P-01/D-01 combo without G-0s for one week time and then I add G-0s. At first I was puzzled with effect of G-0s but, after a while its effect was clear to me! Example: on "Misa Criolla" by Ariel Ramirez(Philips Classics 420 955-2) voice of Jose Carreras is more natural with G-0s then without it! And chorus on the same recording is more powerfull with G-0s! But, these differences are within 5% margin... So, if P-01/D-01/G-0s combo is 100% then P-01/D-01 is 95%! Yes, final 5% of performance for $13K! But, IMO G-0s is a must for any buyer of P-01/D-01, P-03/D-03 or P-03Universal/D-03 combos.
Now, when I know effect(those 5%!!) of G-0s I can not live without it. Call me crazy but,that's the fact.
Guido, I absolutely agree with you that G-0s is actually not important with X-01/X-01LTD at all. This is the reson that I will test cheaper G-25U with UX-3 player to see if there is any effect at all.
