Well thank God for Tobias (especially), Ghost, and Tbg -- y'all saved me from a lot of typing ;--) So I'll just add a couple of things:
First, I highly recommend Keith Johnson's newly ressurected Reference Recordings site: www.referencerecordings.com for both incredible HDCD recordings and info/links. As most of you know he co-invented HDCD.
Second, regarding HDCD decoding: The new(er) Levinson DACs and CDPs use a proprietary Levinson HDCD decoding chip, not the ones normally provided as OEM parts to most manufacturers. However, software-based DACs, such as my Wadia 27 and some others, do a perfectly marvelous job of decoding HDCDs. And even though you don't get the HDCD indicator light, some folks (like Steve Huntley @ GNSC) feel the Wadias do a better job than the HDCD implemented DACs.
I'll say one thing, I can usually tell (blind) if an unfamiliar disc is an HDCD or an XRCD (but not which is which ;--) Let's not do it here, but I'm going to start a thread for listing favorite HDCD/XRCD titles (if no one's done it yet ;--)
BTW, I agree that any bit-for-bit burner should copy an HDCD or an XRCD faithfully.
