Sighhh... A good USB cable really does sound better.... way better. This phenomenon isn't caused by bit errors. It goes beyond our expertise here to talk about it with any degree of authority. If the issue were simple bit errors, the difference between an average USB cable and a high-end USB cable would not be manifested as a loss in sound-staging, frequency response, dynamics, pace, (add your own here) and the subtle nuances that make music so enjoyable to us. If a most-significant bit error occurred, then such errors would result in a click/pop artifact. That not what happens between run-of-the-mill and high-end USB cables. If bit errors were responsible, the musical integrity would come and go, it would be intermittent. That doesn't happen either.
Please move past the theory and try it on a nice system... preferably not a Yamaha receiver. Go visit a good dealer (or perhaps find a nice company with a trial period), bring your nice $20 Belkin USB cable and ask them to swap it out with a really good USB cable. Start to finish, it should take less than 15 minutes (well maybe an hour, because like all of us who have done this, you'll go back and forth 3 times in disbelief)..If you have invested in computer-based music, and you don't do this, then you're leaving musical performance that you paid for on the table. That's sad... and that's why I took the time to share my experiences with all of you. Don't let the lack of explainable theory keep you stuck in the land of mid-fi. Once you hear the difference, you can enjoy your music more than ever, and then still go back and try to understand it... but good luck... you'll need it. If any of you really do take the challenge, then report back what happens. That would make me happy. Better yet, PM me as I don't expect to participate in this discussion any further..Bye guys. Happy Listening... I tried my best...
