Looking for optical isolator for audio

[FastEddy]

I found the link to a company that makes optically isolated amplifiers ( http://www.edgeamp.com/technology.html ) ... and knowing the value of such isolation for digital devices, I would like to incorporate such in my next amp project. I would like isolation to 100K Htz & +/- 10 Volts or greater than >= line level input.

Anyone know of a good set of optical isolation chips or technology for this ??

( I already know the value of digital optical isolation as applied to high end audio ala : http://opticis.com/product_5.htm )
