I have a total of six accessories that take optical audio (PS3, 360, HD Cable, PC, and TV with the Wii attatched), and only one optical audio port. I'd like to rectify that, and am seeking an optical audio switch. I was directed to this switch by a few people, who assured me there would be no loss in audio quality.

The only issue is that it's three ports, and I need six. Is there any device that goes up to six, but is only slightly more expensive? Or would I be able to buy two of the three-port switches, and hook up one to the other?

I use two of these Inday switches, daisy-chained, for a total of seven inputs:

A little pricey, but IR-controllable and built really well.
