Upgrade1394, what is comprised of your system, if I may ask? I was curious as to why Toslink sounds better for you as I too find Toslink to sound better. You said you are using a $100.00 version. I originally started with a $50.00 Audioquest and upgraded to a little more expensive one from DH Labs and there was an improvement. I have not researched all the Toslink models, but with the connection being of key importance, you could spend probably upwards of $200-400.00 for some fancy Toslink models,but is there a limit as to how good the cable can sound ? in other words, a point of diminishing return.Thanks for your feedback.
