supervij,
I've tried that here, unfortunately there are not many if any at all. Most of the people I've talked to that work at record stores or used music shops just look blankly at me if I ask for DVD-A or SACD. They think I'm talking about a concert DVD or something. Either that or they show me a DualDisc, and I say, well that's close, but not quite what I was looking for.

So far Fry's and Best Buy here have had the greatest selection, probably because they actually have a section for that kind of music. The only two so far that I have found anywhere nearby me to have a separate section for that kind of music.
