No offense against you but that sounds like a bunch of hocus pocus snake oil to me. Digital is just one's and zero's. It cannot be reproduced any less or any more, unless you get some sort of data corruption. Where I can see the sound being affected is in the amp or any sound shaping devices like EQ. The only advantage to coax that I can see is the strength of the cable. arb226: Yes, that is why I assumed the bit-rates are the same. Again, I don't want to offend anyone, that is not my intention.
