I've owned an LP, 1/2 speed LP, Japan CD, remastered CD, deluxe box, 2CD and SACD 5.1 of Stranger. My hunch is that the Columbia SACD sounds best and the MoFi SACD is the same, or very close in 2ch. I've owned all the same pressings on 52nd st, except there wasn't a 2CD or deluxe box. I'd also expect the Mofi & Columbia SACD's to sound identical in 2ch.
I've owned an LP, Japan LP, Japan CD and remastered CD of Nylon Curtain & Glass Houses. I would expect the SACD's, which I have yet to pick up, to be the best.
Does the Gold disc of 52nd st sound better than the SACD's? It's possible, but I highly doubt it. It is probably EQ'd differently.
