Which Steely Dan Aja lp to buy?

I think, and this is a think, that you rely on Kevin Gray. He does a lot of work with Steve Hoffman, a fellow highly recognized for remastering. His surfaces are quiet, too.

I would go for an original ABC.
They can be hit or miss, but when they are good, they are good. I have not heard any positive talk about the remasterings.

the universal import will be from the original masters too. the original abc pressing is a classic.

G_m_c has a good point: this is one LP where the original pressing, readily available, can sound great. I'll be curious to hear side-by-side comparison reports when the reissues come out.

Yup, the original ABC. They're everywhere cheap. In the dollar bins at used record stores (or certainly very reasonably priced), record shows or the thrifts. Chances are you can buy 10 of them for the price of the re-issue and out of the 10 you'll be bound to get a couple of decent copies that probably sound better than the re-issue.

I can see buying re-issues if there is difficulty in obtaining a clean copy of the original. That's not the case with AJA.
