Hey Stabie, like you I'm new to the DVD-A and SACD party. For reviews try http://www.highfidelityreview.com/reviews/dvdaudio.asp?offset=25 they have been pretty accurate so far.
The local C.C. and Bestbuy have next to nothing so I've been buying everything online try http://www.dvdpricesearch.com/ and in the search field type in DVD-A or SACD and they will list all selections as well as the best prices. Good luck and if you come across any good titles pass them on to the rest of us.
