Optocoupler or Optoisolator for Audio

[kgeorge123]

Hi,

We have two channel audio to be seperated from the final stage audio amplifier.
Now becase of different products the final power ampifier keeps on changing and we come across gounding loop/ humming noise.
I know that optocoupler could be used to eliminate this.
Does any one knows any good one for audio (analog).

I am looking for.
1. Analog Optocoupler
2. Least THD
3. no ageing effects or possibly eliminated.

thanks
