Here's how the analog signal systems break down:
I never said that, FYI. I was restricting my points to A/V wiring, much less excluding DVI (which is clearly in this class). I was not speculating on general wiring and signals (of which I have almost no knowledge). > Component: 3 separate coax cables with RCA jacks.

I've always seen HDMI/DVI as the choice for high end connections.

Kind of what I expected. Didn't know that component did quite so well. -- Scott Paul Robertson http://spr.mahonri5.net GnuPG FingerPrint: 09ab 64b5 edc0 903e 93ce edb9 3bcc f8fb dc5d 7601
