Yes, thus why I said only "a bit". Most likely not enough to be of any 
significance to the vast majority of people, but I can definitely see 
the argument that a signal having to be translated from one medium to 
another and back is bound to have a wee bit more loss of signal than 
one that never needs translation during transport.

Good point. The superiority of coax over optical argument does assume 
you have high-quality coax cables that are well-shielded. Optical might 
be better if you have an issue with lots of electrical interference. 
Optical also has the advantage of being able to span much greater 
distances, so if you want to put your stereo 500" away, you can... :)
