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.

Germanboxers - the X-01 limited has about 100 part upgrades over the X01 and UX-1. The changes as I am understand them are as follows:
1. The RCA output jacks are now WBT Nextgen jacks
2. The Digital output jack is now WBT Nextgen
3. Internal wiring has been changed from Van den Hul silver wiring to Acrolink 6N copper wiring - same as used in the P01/D01 Esoteric combo
4. Changes to the connectors, capacitors and resistors in the output stage to the same ones that are also used in the P01/D01.
5. An improved stock power cord based on Acrolink copper wire - same as the one used in the P01/D01. However, any of the esoteric products benefit greatly from aftermarket power cords and as Branimir says above, they also should be run in balanced mode.

Hope this helps. Arnie
Jordan, price for G25U is $3K in USA.
Teajay,Guido and all other guys-here is a link to 6moons Srajan Ebaen Esoteric G25U review:
http://www.6moons.com/audioreviews/esoteric2/g25u.html

Although I personally do not like Mr. Ebaen writing style or his system I think this is his best review yet. It is not positive or negative, you will see... Technically, it features several topics that may be interested for you. Please, comment this review here after reading it!
Hi,
I have tried the Esoteric G0s clock with my X-01 in my system. I had in my system for a week and a half, listening for 2-3 hours per day. I then removed the clock and listened again. I could not hear any difference. I am not saying that it didn't have an effect, just none that I could hear. For a separate experiment, I tried to hear its effect by turning it on/off during playback of an individual CD track. Again, I could not hear any difference. I have also tried the APogee Big Ben clock that is mentioned in the review - again with the same results. I have no doubt that with a combo unit - the P03/D03 or the P01/D01 that the G0s clock makes an audible improvement that I would hear, but with a one box player of the caliber of the X-01 or X-01 ltd, its extrememly subtle at best and I would agree that the $13,000 is better spent elsewhere.
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,
Steven
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!!
