The Auzentech is a warm sounding laid-back unit (I used to own one) compared to many other DACs. The ODAC is on the lean side (comparable to Benchmark DAC1). Try LM4562, it's less strident and more laid back than the stock OPA2132. Biased into class A, the LM4562 gets slightly warm sounding. You can also try OPA2604 or JRC/NJM4556.
You can always EQ.
Thanks for the info Purrin. I definitely agree that the ODAC is leaner than my Forte. It also has superior detail and separation. I probably should have kept my HRT MSII. It is also has fantastic detail without sacrificing bass. I did have issues with static and popping while using WASAPI with that though.
This hobby... It can be frustrating.
Oh well, such is the life of a headphone junkie.
