Has anyone compared the two for sound quality? just curious because, the 2134 is around $2.00 and the 2132P is about $5.00 yet, I seem to see the 2134 metioned alot more. by the way, these are used for 2 channel power amp input purposes. Thanks for all opinions! 🙂
I will say one is probably a tiny bit better
but I wont tell you which one.
Find out for yourself 🙂
They are not so expensive you can not try both.
And use the other one for some other future audio circuit.

The OPA2134 is only available in the (PA) variety while the OPA2132 comes in (P) and (PA). The OPA2132(P) is more expensive because it has lower input offset voltage, better common-mode rejection, and higher open-loop gain.
It would probably only be fair to compare OPA2134PA to OPA2132PA, though I'm not sure the slightly better specs of the (P) version would make much difference for audio applications (at least not to me).
I have all three if you would like to compare them for yourself.

just looking for simple opinions that's all! I don't trust my ears much any more but, from now on, I will be sure to ask on another forum 🙄
To my ears, they're identical soundwise, when they work, but the OPA2132P seems slightly more stable, and will sometimes work in a circuit where the 2134 is oscillating or marginal. So for design purposes, they're largely the same, but if you're rolling opamps in existing equipment, you may be better off going for the 2132.
