I, too, would like to know the best place to get SACD's, e.g. online. I'm looking for ones besides all the Sony/Columbia ones that Best Buy has, e.g., Human League - Dare; Best of Simple Minds; Frankie Goes to Hollywood - Rage Hard (yes, it's just another best of); Cowboy Junkies - Open; etc. Some of the Hyperion ones, perhaps.
The selection around here is miserable. I found the SACD's stowed with the DVD-A's, DAD's, and DTS CD's at Tower; at Borders, they say, "what's that?" (my answer: it's another high-resolution format like DVD-A [they start to lead me towards the DVD-A's] but different [they stop...pause...look at me like a deer in the headlights...shrug...].).
PS This was my 2000th post. Now I can get the headruloaner blockhead. Of course, don't have time for it right now, but now I can, anyway. Will do so at some point in the future.
