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.

When it comes to separate Transport and DAC boxes, an external clock is beneficial as it syncs them all (frequency, not phase).

When it comes to stand alone unit like UX-1 and X-01 for example, external clock is of a little to no benefit. It will sure make the actual clocks in the player rock solid in terms of long term (and temperature dependant) frequency stability, but that's about it. This does not have any sonic impact as the long term frequency stability affects the playback speed only. Since the clocks are very high frequency, the usual long term frequency change results in speed fluctuation that can not be even measured with precise meters, not to talk about your ears.

External Clock will not improve the peak to peak (short term) jitter performance of the stand alone player internal Clock Generators (or transport and DAC internal clocks) which actually is the most important when it comes to clocking digital.

Alex, I suspect you may be correct. It was exactly my guess. . . that the external clock will make a difference mostly when synchronizing multiple units. But I will give the G0S another chance in a couple of weeks in a friend's system. It will be an interesting yet academic exercise, as I do not plan to get one, unless it truly blew me away, which I suspect won't be terribly likely.

Looking for input and comments about the Esoteric D-70 D/A when matched with the Esoteric P-70 transport (for redbook CD only). Any A-goners' personal listening experiences are welcome. Teac/Esoteric indicate that this combo is still their reference for redbook CD, notwithstanding the introduction of several products that also handle SACD (i.e., X-01, P-01 and D-01, etc.)

From my reading of several reviews, P-70 and D-70 fall into Teajay's #1 category, but do they sit all the way at one end, as far from category #2 as possible, or is their sound more refined on the top end, so that they are in the middle of #1? (This assumes we can theorize Teajay's categories as a continuum).

Appreciate any thoughts and comments.

Audioesq-Esoteric D-70/P-70 combo is #1 flavor. It is still excellent sounding gear but, in direct comparison with D-01/P-01/G-0s it was clear that new combo is better( in RBCDP). D-01/P-01/G-0s has more refined and little bit deeper bass, more presence in midrange( specially on male vocals ) and highs has even more extension and refinement.
My friend owns D-70/P-70 and is very happy with it but, even to him it was cleary that D-01/P-01/G-0s combo is better... He also had a chance to compare D-70/P-70 to new X-01 and for him differences were small( but, in X-01 favor!) so, he will keep D-70/P-70.
If you wan't little bit warmer sound you can add CEC TL-51x cd transport to D-70/P-70 combo. CEC TL-51 is not very expensive and it is warm sounding CDT.
D-70/P-70 is straight #1 flavor as possible but, very good sounding one. Also, sound of D-70/P-70 is best with active preamp in system( around 10-20% depending on preamp) than with Esoteric's volume control.
You can also read TeeJay's comments on CEC,Guidocorona's on X-01 and mine on D-01/P-01/G-0s.
Very important thing is price since D-70/P-70 is not any more availabile in Usa and Europe. If you fing it at very good price go for it. Build quality is far better them most of the other gear in this class.
Happy hunting!

I confirm subjective impressions of redbook sound of D70/P70 so close to X-01 to make comparison a little difficult. P70/D70 withdrawn in North America. Newer VU version available only in Europ/Asia. Also fair to remember that D70/P70 approx one quarter the price of new P01/D01 combo, and likely half the price of new P03/D03 two box combo.
