RE: OPA2134 vs OPA2604 vs OPA2107

Posted by KanedaK on December 24, 2016 at 02:21:53:
Thanks for your answer.
Right now I'm gonna let the opa2134 burn-in a little bit more but I know myself, I won't resist long the temptation to order a few LM4562.

I was thinking the same: 4562 as buffer and on the high-pass.

I'm using gold plated, machined sockets - I'm not giving up on using SS3602 from Sparkos labs one day and this is all a "temporary" solution. But I know I might well find the perfect balance with regular opamps and leave it as it is forever. I've stuffed a 0,1uF MLCC capacitor under each socket between pins 4 and 8.

I've replaced the coupling caps with back-to-back Silmics II (-++-) for now but I might add some bypass or squeeze some bigger film caps instead but that can wait. Back to back Silmics sound surprisingly good.

I've replaced the PSU caps with Nichicon muse KZ. One would argue that you don't need "audio" caps in that position but it sounds better than before so I'm happy with it.
