@Stingreen: Why? I'm open to suggestions, but over the years I have found polished glass optical to be comparable to coaxial. It depends on the equipment used. I hear people say coaxial is better, but why? Is it because of an objective technical flaw or subjective listening?
In regards to Apple products, optical is the only choice, so going coaxial is not an option. I know that I can use the USB/Coax converter, and I have several around and they work great, but I'm wanting to know what the best options for glass toslink (or any order toslink) cable are.
