I had a Codex… it replaced an Ayre QB-9…
sold the codex and bought a QB-9 DSD…
far more pleasant to me..
Last year I sent the QB -9 in for the twenty upgrade.
also bought a benchmark DAC3…
The benchmark is excellent, but digital to my ears. Extremely articulate with very tight and forceful bass response. However in my system the detail retrieval Comes at the expense of a relaxed presentation..
The QB-20 ayre is amazing…
Very revealing and rich without loss of space and air.
soundstage is definitely deeper than the benchmark too..
If you can find a used QB-9 the upgrade results in a remarkable DAC..IMO..
Beware…it’s takes forever to sound right/ break in…
I almost gave up on it…
