I have an original MFSL gold CD, MFSL standard vinyl and the UHQR, all purchased new back in the day. The CD is good, but not great IMO. The recording seems to suffer from being digitized, at least in comparison to the vinyl copies. Probably because it was such an early conversion attempt. The MFSL standard vinyl remains a go-to test LP in my collection, but the UHQR is one of the very best vinyl rock pressings I've ever heard.
I haven't heard the BD, but did pick up a few interesting BD performances recently, including Return to Forever and Yes, both live at Montrose. Being much newer, digital multichannel recordings in the first place, I feel those performances really benefit being in BD format. I'm not sure a strictly audio remaster from what was originally an analog source to BD would be as pleasing.
Similarly, I've tried a few SACD remasters of stuff originally recorded on tape and found them vaguely unsatisfying. One is the Billy Joel Piano Man MFSL. They do have much more "headroom" and you can clearly hear that the material isn't getting anywhere near the performance edge of the medium, but that doesn't make them any more musical.
It is my understanding that the Oppo 103 has a very good BD section, and the Ayre has solid CD capability. At a guess, you'll probably find the sound quality a tie between the two formats / decks. Maybe start with the less expensive disc and go from there?
Part of the magic of the hobby - you pays your moneys and takes your chances. Good luck & happy listening!
