A moderate priced dac

I went through this awhile ago. Bought a Hegel HD12 which bettered anything else I could find at the price point ($1400, IIRC).

Another one you don't see much press on is the Monarchy NM24 preamp/DAC. Look up Dick Olsher's review in TAS a few years ago. You can find those for a few hundred used now.

DACs seem to depreciate faster than anything else - I have on in a third system that cost $6000 new and probably would bring $600 today.

I got a used Rega DAC for just under $500, and have been loving it. 

I agree with Mahgister. Here's a good example. The AZ AV Club recently had their DAC-It-Out at a local audio store. The team in charge did a really outstanding job; meticulously set up with precise level matching, etc. Very nice room with $118k system. Out of the ten DACs, even though highly reviewed with impeccable specs, the Benchmark came in dead last, consistently. The Chord Qutest, mentioned above, was in the top three.

Curious if anyone has changed from my current DACs,  Peachtree IDac and Ayon Cd 07 and what your observations were.

My experience on DAC choice: I bought a McIntosh D150 one year ago. I have done countless comparisons Bluesound Node 2 + D150 + Amplifier vs Node 2 + Amplifier. I am not able to hear any difference. For my ears, with my speakers and amplifier, thje Node 2 DAC is as good as the D150.

So my advice is: compare the two DAC (old and new) on your system before buying it.
