Thanks for the reponses. Obie - my DV-37 is hooked up through a digital optical cable. I haven't tried analog as of yet.

Anyhow - an update. My hardware for my rack came in yesterday so last night I finished off the rack. This let me hook everything up properly - including my sub. Anyhow the CD from the Pioneer is much, much better. It was getting late so I didn't do too much critical listening. I ended up listening unsampled, but again, that wasn't a choice based on careful listening. I hope to do that tonight or over the weekend....
