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 discovered this thread and would like to respectfully add the Metronome "C2A Signature" DAC. It has a tube output, a separate matching chassis for the elaborate power supply as well as other advanced features.

The Metronome C2A Signature seems to capture very low level resolution quite spectacular but sounds more analog than digital. I am convinced the robust power supply contibutes mightily to this achievement.

If anyone has questions, please contact us off board through our website http://www.tmhaudio.com

In his article Digital Zen Dick Olsher wrote:
"In my experience, zero oversampling gives the impression of a more believable soundstage. The spatial impression in terms of depth and width perspectives is typically better defined relative to oversampling designs. It is as though the auditory system is presented with a better set of cues with which to synthesize a 3-D impression of the auditory stream."

This is what I've experienced as well. This is a quality that is outside of our "Category 1 vs. Category 2" dichotomy. Some DACs get this right and some don't.

If we were to present the "Category 1 vs. Category 2" model as a scale from 1 to 10, with 1 being extremely Category 1 and 10 being extremely Category 2, then I'd might rate my preference as a 7. Having said this, I would rather own a DAC that registerd a 1 on this scale, and got the spatial impression right, than a DAC that was a 7 and got the spatial stuff wrong.

As Ajahu says, it is the difference between listening to "real music" as oppossed to a "wonderful hifi reproduction of music."

Exlibris, sorry to disagree with you on this one, however I have found no correlation between non-upsampling DACS vs upsampling DACS regarding a more " believable soundstage". Now, all the non-upsampling DACS I have auditioned were tube based, and my hunch is that you might find this type of sonic presentation more pleasing then SS DACS.

So, I don't think that the spatial qualities of non-upsampling DACS is superior to upsampling DACS, in my experience, and that either strategy is superior to the other. Both upsampling and non-upsampling gear can offer great performance.

Teajay,
No worries; we'll just agree to disagree.
To be honest I probably haven't heard a big enough sample of both types in my system to really draw that conclusion.
As for 'tube vs. solid state,' I've never heard a tube DAC in my system. Like the Attraction DAC itself, everything has been SS (ARC; EMM; dCS; Accustic Arts; MSB).

Just had a new acquaintance, who happens to sell hi-end gear and is an experienced audiophile, come over to listen to my rig.

His major references are Meitner and DCS. He was amazed at the sonic performance of the Accustic Arts DAC1 MK4. He found it to be just as detailed/dynamic as the above mentioned digital front ends, however he thought it was more "real and more naturally musical" to use his words.

Well, its always good for the old audiophile "EGO" to have someone knowledgable to give your rig kudos, but I wanted to share this because I think the MK4 really is one of the better references out there, at a reasonable cost. My new friend is seriously considering auditioning the Accustic Arts piece to replace his much more expensive DCS front end.
