Miles Davis - CD, Lp, pressings comparisons


After substantial equipment upgrades, including refurbishing my turntable, I'm really enjoying vinyl. Now I'm focusing on Miles Davis. I'm curious to hear opinions of those who've done comparisons, sound-wise, between the following issues:

'50's material (Prestige, Blue Note):

Early pressings (Lp)
'70's remasterings (Fantasy two-fers)
Japanese pressings (Lp)
OJC or other relatively recent Lp versions
XRCD's
Rudy van Gelder (RVG) CD remasterings (recent)

Columbia material:

Early vs. later Columbia pressings (Lp)
Japanese pressings (Lp)
Recent digital remasterings (which appear on CD and some Mosaic Lps)

There are a couple of threads that cover these issues to some extent, but I'm particularly interested in hearing about the 70's Prestige remasterings, and comparisons between the later CD remasterings vs. earlier Lps. For example, how do the XRCDs hold up as against the Lps? Or the RVGs against the XRCDs? By way of further example, I compared a couple of the XRCDs to the RVGs and thought the RVGs were a bit more "mellow" and easier to listen to. But I've never compared them to Lps.

Curious to hear others' thoughts.

More comparisons to report on my end: I compared an early Bitches Brew Lp to the recent version of Bitches Brew on CD (from the Complete Bitches Brew sessions set). Both were very good, very listenable. The Lp had a bit less bass, and the treble was softer, very natural, and easy on the ears. The soundstage was wide, and there was good midrange warmth. The CD, on the other hand, was as good as CDs get. As with the later Prestige release of Bag's Groove, described above, it was as if the engineers/producers recognized the ways in which CDs can annoy, and "tuned" the production to avoid that. The treble was crisper than the Lp, but not annoying. The bass on the CD was better grounded than the Lp. The soundstage was a hair narrower, but quite good, and the midrange was warm and cozy. The highs on CDs can sound somewhat artificial and "splatty" (to me)...there was almost none of that on this CD. Finally, if this CD was missing the detail of the Lp, it was not particularly noticeable. I just got caught up in the music. (What I did was started Pharoah's Dance on the Lp and CD at the same time, and just switched back and forth. Not very scientific, but good fun.)
Try the hybird SACD of blue. Amazing sound in that it recreates the original master tapes three channel mono capture, no mixing. This assumes you have a three channel set up. You play it as it was. I have the other cd's and lp's and they all do not match the hybird. The sound stage, depth of image is so real.

The Mosiac 200 gram Vinyl box set from the Bitches Brew Sessions are outstanding too.
