Kevin, truth to tell I don’t know how to distinguish the Santa Maria pressing from the others. I know from reading various threads elsewhere that the SM press is generally considered best of the AB1006 presses, but mine is hand written AB1006-A and AB1006-B in the dead wax. Whether it’s a Santa Maria (CBS) press or not, I don’t know as there’s no other indicator. What I do know is that it sounds very good, and appreciably better than the early UK press I own. Now, I don’t own the much revered Cisco reissue, and nor do I own the much reviled Mofi LP either, so I cannot say I’m an expert on Aja issues. I do have a near mint copy of the AB1006 US issue and a totally mint early UK issue cut by Allen Landau (usually not a good omen - sorry Allen - but this is one of his better cuts). Note that Allen Landau should not be confused with Allen Zentz, who cut some fabulous SD LPs. I also have the 2008 Back to Black reissue of Aja cut by Greg Moore at Masterpiece. The B to B is actually rather good, if a bit more “hifi” and likely from a good digital source rather than analogue. It’s cut fairly hot and has good clarity and surprisingly good dynamics, brighter than before and with a stronger bottom end. But it lacks the luminosity of the US original and you sense that the AB-1006 is at least one step closer to the master tape.
Anyway, as I say, I’m no expert on Aja, even though I seem to have a good foot and a half of shelf space given over to Steely Dan LPs.
