Supposedly, there is a new Wireworld Toslink that is supposed to be very good. Obviously, how good the cable compares to coax is going to depend on how good the optical converters within the transport and dac are. Sean
Toslink $14.99 for 6 feet Recoton from Fry Electronics. I connect from Panasonics DVD/CD RV-31 ($200)to Wadia's and direct connect it to the amps. In my system, it's only second to AT&T Glass fiber. I have a different transport that I connect using AT&T glass fiber optics cable, sound incredible, but that is for a different thread :-)
Long a toslinc basher;there are some components where there is no choice. My Panasonic HD 20 direct sat box(called STB)has only this hook up. Going into my Meridian processor the 5.1 feed from Stars/HBO/ Showtime causes one to rethink toslinc. Not bad at all. I have a choice on the Pan. dvd player; THAT choice is coax,for me. So, for the STB,I make good lemonaid.
