In preparation for testing my upcoming Bravo D-1, I installed the Sony DVP-S7000 DVD Player in my rack, below my Sony DVP-NS700P. I unplugged the 700's Component Video and Glass Toslink and plugged them into the 7000. The same cables, same DVD, and everything else. No other changes.I didn't think that there would be any difference in the sound if the output was digital. I was really looking at the video quality. The 7000 has noticebly better and more clear sound, expecially the lower frequencies.
Anyone have any thoughts on why one would sound better?
Thanks... Paul

Glass toslink "can" be better than coax, but often isn't. It is the jitter in the transmitter and receiver modules (and the whole transport for that matter) that can determine the quality of the sound. Often, the toslink transmitters are worse than the coax ones. In your case, it sounds like the 7000 is just a better transport.I had to change from coax to toslink in my HT, as the coax was driving my stereo-only DAC. Well, the (plastic) toslink connection is far inferior. It sounds "smoother" at the cost of losing the life and detail of the sound. There really are serious differences in sound quality, even in Dolby 5.1 or DTS, with different cable/transport combinations. Should there be? NO -- I think the HT receiver should be able to clean up the jitter. But, sadly, they don't. Only high-end stereo DACs tend to have good jitter rejection. Home theatre systems still have problems.

Glass toslink is inherently superior to copper wire. Copper distorts the signals because of resistance, inductance, grain structure, impurities, etc etc, get the picture. coax is inherently flawed. Glass doesn't have any of those problems. I use a sonicwave glass toslink form cablesamerica.com for $25. It sounds excellent. give it a try. It will be worth it:)
