I just got my two OPA637's in the mail. I put them in my Pimeta, and wow, they do sound good. I can hear the ambient space of the room/hall so much better than any other opamp, and the bass is full, deep and tight. Soundstage is respectable, detail is lively and musical...verrry nice.
I'm having trouble finding a good match for the ground channel, though. The AD744 sounds OK, but not very exciting. The AD829 seems too intense; things get super thin and punchy. I tried the LMH6654 in ground, and it sounds good but there is a hiss when I turn the amp on, which slowly dies down but is still very audible.
I know the OPA627 is the traditional match for the ground channel, but what else works well? I'm thinking of trying the AD825 and AD8065 next.
