Rich,
Your post is very informative and interesting ... Thank you.
I had a Benchmark DAC1 (with the PCX XLR mod) but not the Bel Canto ... your analogy is understood :-)
I've decided to go with ASI Liveline. Srajan tells me it's worth a try ... it replaced all the cables in his system ... so far he has not mislead me yet :-) This could POSSIBLY replace all the cables in my system too.
