Any opinions on the Texas Instruments equivalent, part number RC4580? The specs are the same, but I would think that the actual construction is different, and that the sound will be different too. I just replaced a bunch of Mitsubishi M5218's with the TI RC4580 in a receiver that I am repairing, and I am so far pleased with the result. The noise floor is definitely lower. The specs say that the TI RC4580 should sound better; anyone with better ears than I have ever listened to it specifically and have an opinion? I am sure that TI produced this opamp in order to gain some market from all those that like to use the NJM4580/JRC4580; do you think that TI did a better job on their version than the Japanese did on their own?

Most likely! TI was one of the first in audio opamps so they must have learned something building the old TL07/08x series.

I think you should replace NJM 4850 or M5218 or 5532...by opa2107/2132 or at least Lme 49860,depends on your taste!!!

Essentially all 8 pin dual opamps are pin compatible with each other. MC33078, NE5532, LM833 are some suitable replacements.

This is a very old question revived by a newbie who doesn't read dates.
