Re: Hoffman -- I've been quite pleased with the sound of the Miles XRCDs and hadn't thought about investing in the DCC versions -- until, that is, a few days ago when I heard his Evans 'Interplay' re-mastering. Woah!! I might need to saddle up and start tracking down some of those Miles (and Evans) ones.
You won't be disappointed, the Hoffman remasters smoke all other versions I've heard (OJC, K2, XRCD, etc.). They're pretty expensive, though - if you can find them, that is; they've been OOP since the demise of DCC and are getting scarcer by the day.
