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.

Many thanks for your thorough and even handed approach. It’s exceedingly generous of you to expend such time and effort.

Based upon your review, the Aero appears to be (for me) disappointingly consistent with what appears to be a major trend, currently-- audio gear that sacrifices upper bass/lower mids for the sake of an emphasis upon upper mids/highs.

Unfortuately, not my cup of tea.

 

@mitch2   Thank you for the write up on the LTA Aero Dac.  Very informative and well written.

Out of curiosity, what tubes were in the dac?  I ask because the sound from my LTA MicroZotl preamp varies greatly with different tubes.  A kinda pricey set of Telefunken sounds the best.  LTA didn't ship it with them, probably due to the cost.  The tubes sent with it weren't all that great.

measurements provided in the consumer documentation are for advertisement purposes only that do not reflect actual measurements. that's good place to start, then you can work on further issues with or without measurements. 

@mitch2 

Thank you for the significant effort required to evaluate and then inform the community of your conclusions.

Personally, I find it very helpful.

Thank you once again,
