Frank, I just acquired a Japanese Aja. I'll let you know what I hear when I receive it (which hopefully will be this weekend). I also have the Aja original transfer, the MoFi, & the Box version. Again, I believe I really need to get the latest (1999) "standard" remaster to compare as well. I believe the latest MCA versions, like the "mini LP", also have complete liner notes which, alone, justifies the purchase of either version. As Ben pointed out, those cats are hilareous. eBay is the only source that's even vaguely competitive on price. There are a few retailers scattered about (I can't remember any names), but the cheapest I've seen Aja is $75.00. Amazon.com advertises them, but they have never filled an order for me. The item simply never ships.
Ben, I was under the impression that the Japanese remastered versions were Japanese remastered versions, but I am not certain. I will do some more research and let everyone know what I find. It could very well be that they're the same remaster repackaged.
I've posed these sorts of questions to SteelyDan.com before, but have never gotten a response. I also asked about, what was at the time an unconfirmed, DJ only Kamakiriad that was gold and SBM. The response was something to the extent that they had never heard of any such thing. It exists. I own one. It's legit. That site is not set up for these types of questions.
Thanks everyone for contributing.
