ASUS Xonar STX Op Amp Help

post #1 of 3
Thread Starter 

New member here: I know this has been asked time and time again, but I cant seem to find a good answer to my question with searching. From what I understand the STX has 3 op-amps which are swappable? One for each channel and then an integrator. I just ordered some samples of the LME49720NA. Can I and should I upgrade the third op amp? What will upgrading the 3rd op amp do? Currently I am only using the STX paired with my MDR-V6s but am also considering getting some monitors in the future. Also on a side note, are there any other op amps, other than the LME49720NA, that I should consider swapping in?

The LM4652 (stock buffer op-amp on the STX), LME49720NA and LME49860NA are the same op-amp.

The LME49860NA is the cherry pick (better voltage range) of the LME49720NAs.

For around $15-$18 you can replace all three op-amps with the LME49860NAs.

I ordered some free samples of the 49720. Maybe I can try and get some more samples of the 49860 :P

Thanks for clearing it up!!
