Six DAC Comparison


I am in the middle of comparing the sound of six different DACs in my system. I own them all (I know weird) but one of them is still within a trial/return timeframe.

Not to share specific comparisons today, but a couple of observations so far are that first, they all definitely sound different from each other. On one hand, they all sound pretty good and play what is fed to them without significant flaws but on the other hand there are definite sonic differences that make it easy to understand how a person might like the sound of some of them while not liking others.

Second, raises the observation that most of them must be doing something to shape the sound in the manner the designer intended since one of the DACs, a Benchmark DAC3 HGA, was described by John Atkinson of Stereophile as providing "state-of-the-art measured performance." In the review, JA closed the measurements section by writing, "All I can say is "Wow!" I have also owned the Tambaqui (not in my current comparison), which also measured well ("The Mola Mola Tambaqui offers state-of-the-digital-art measured performance." - JA). The Benchmark reminds me sonically of the Tambaqui, both of which are excellent sounding DACs.

My point is that if the Benchmark is providing "state-of-the-art measured performance," then one could reasonably presume that the other five DACs, which sound different from the Benchmark, do not share similar ’state-of-the-art" measurements and are doing something to subtly or not so subtly alter the sound. Whether a person likes what they hear is a different issue.

@yyzsantabarbara   My modest Hyperion HPS-938 speakers (that I believe you're familiar with) work great with DAC3HGC+AHB2,  Sometimes warmer sound (2nd or even euphonic 3rd harmonic) helps to cover "hot" tweeter or distortion in the system at the cost of very little loss of transparency (no right or wrong here).  Benchmark gear is extremely revealing - punishing in some systems and wonderful in others. I believe you graduated to higher end speakers, but proper matching still remains true

To me, having heard both, it is a stretch to compare the Benchmark with the Tambaqui; The Tambaqui is so much more musical and engaging.

I have 3 DACs including the Benchmark DAC3B. The DAC3B is used with warm my gear. Too much warmth for me is a no go.

After my experience with a Benchmark DAC years ago that got rave reviews but for which I hated the sound (ear-bleeding highs), I learned something.

There is sound.  But there is also music.  They are not necessarily the same thing...

Just purchased the Mojo Audio Mystique X SE  (sabs z chips) I can't wait to hear your thoughts.

The Benchmark DAC3 was SOTA when originally released. Its measured performance was surpassed by cheaper DACs years ago. These days there exist $200 “Chi-Fi” DACs that objectively outperform the DAC3.

A daunting task to coordinate and evaluate to say the least. May the Force be with you.

 

@mitch2 

Yes, what an awesome experiment!

I can’t wait to hear your thoughts.  
Please include what you used as a source… streaming/cd etc and what kind of connection… Is2/aes/coax/usb, etc. 

Thank you for taking on such a time exhausting task for us all 👍

Best wishes,

Excellent!  Thanks for listing the contenders — great selection and really looking forward to your thoughts/impressions.

Also, for lower level DACs part choices are made on just choosing appropriate parts or on cost not sound. Also, it takes a lot of experience to just figure out the “sound” of different capacitors and resistors and where they are put in the design… etc. different competence is critical as well as being able to hear the results and on what system one hears the results… it goes on and on… and everything is time consuming.

My point is that if the Benchmark is providing "state-of-the-art measured performance," then one could reasonably presume that the other five DACs, which sound different from the Benchmark, do not share similar ’state-of-the-art" measurements and are doing something to subtly or not so subtly alter the sound. 

Or everything that impacts sound isn’t measured or measured fully, which is very likely the case.  Please share what other DACs are in the comparison — no reason not to at this point and would be good to know.
