Burr Brown® OPA2134 vs R4580

Mar 15, 2017 at 11:52 PM Post #3 of 3
OPA2134 is a FET opamp and has its own unique benefits but isn't as low noise as R4580. As for BB OPA2134 sound, it sounds better to me than the R4580 and is less fatiguing. The R4580 is probably better spec wise but sometimes distortion of a signal to make it warmer (quieter treble) is a good thing. The bass on the OPA2134 is a little stronger as well.
