Does a DVD player do justice to audio (Redbook) CD's for pure audio playback ? I have a Pioneer DV-565A hooked up to my TV (don't have a complete HT set-up yet), so can't really judge at the moment. If a digital connection is used from the DVD player to the receiver, is there any real need for a dedicated CD player ? Further, does anyone have any experience with ex-demo CD players ? I realise there is no standard, but does buying ex-demo stuff make good sense ? Thanks.
