OPA2134 vs OPA2604 vs OPA2107

Posted by KanedaK (A) on December 22, 2016 at 16:38:35

I've replaced the old TL082 in my active crossover with opa2134.

The sound is much better but there's still something a bit "hi-fi" and "grey" in the presentation.
I'd like more liquidity and "bloom" without being too dark or veiled (I understand I might be asking for the impossible- after all, it's just opamps, not tubes- but if there would be a way, I woud try it).

I know OPA2134 is the common choice for active crossovers but I wonder if I coukd try something that would tilt the sound more to my liking.

Some people seem to like opa2107, is it "better" than opa2134?

I've replaced NE5532 with LM4562 in my CD player and they are fantastic, but then i was replacing bipolar with bipolar and now I'd like to replace FET with FET to minimise chances of havoc. (but is that necessary after all?)

anybody wants to comment opa2134 vs opa2107 vs opa2604 in such an application?
