Don't waste your time with CD on HD-DVD. You will get super audiophile quality by grabbing a classic DVD player like the Harman Kardon DVD-48 or any of the OPPO SD-DVD. CD's are simply brilliant on any of them in any CD format. Plus the DVD upscaling is much better than any of the BluRay or HDDVD players. You can actually grab them very cheaply now, since the world has gone Blu. The CD quality is equal to or surpasses audiophile machines costing over $10,000 to my ears. I personally have a latter day Denon 3560 CD player ($3000 in its day). And it can't touch my HK DVD48 for sonic quality. The Denon has been banished to the rec room. The Home theater room has the Toshiba HD-A35 (HDDVD), Pannasonic DMP-BD35 (BluRay) and Harman Kardon DVD 48 (SDDVD & CD). This circulates to a dual wielded 7.2 system featuring the Harman Kardon AVR 745 as the 7.2 Controller. The 745's dedicated 85Wx7 amps feed a full 7 speaker array of Definitive Audio Front & surround monitors spaced in a near ceiling configuration (8' high to a 12' ceiling). The Preamp-Outputs of the 745 feed a monster array of audiophile grade amplifiers including: 2 rare Sumo Andromeda II Stereo amps designed and built by Steve Bongiorno himself (for front & side ear level audiophile speakers); Adcom GFA 545 II for SBR&L ear level audiophile speakers; Marantz MA 700 THX Mono amp for floor level front center; and a Audiosource 5.3A mono amp for one 12" slave Cambridge audio subwoofer, of the (3), 12" subwoofers in the full system. The other two subs are the Powered Main Cambridge Subwoofer (500W), and the 500W Ultralinear.
This entire system presents a 14.3 high-low speaker surround soundstage that is completely spellbinding on audio CD's via the HK DVD 48. And movies via my 65" Hitachi CRT RPTV monitor (fully calibrated and tweaked) is an experience that is too good to describe. I prefer a fully tweaked CRT to fixed pixel anyday. The room is 28'x36' or 1008sf. So it's plenty big.
The real point is this however. Grab one of the audiophile Oppo's or the HK DVD48 from EBay or elsewhere for your CD and SDDVD listening/viewing. You won't be disappointed with either. And Either will be much superior than the HD-DVD player or a BluRay player for CD listening purposes.
