I get most of my high-res music from HDTracks.com and play it through my Oppo. The Oppo is also my goto player for SACD and DVD-Audio. You can find lots of SACDs from Acoustic Sounds online. Sometimes you can find them on Amazon. You can also rip DVD-Audio and stream it, I did that for the high-res tracks (both 2-channel and 5.1) from my Talking Heads cube.If you're a pink Floyd fan, you can get great 5.1 mixes on SACD, and on the Immersion box sets for Dark Side of the Moon and Wish You Were Here, really spectacular stuff.MFSL keeps releasing SACD, you can find them on Amazon. There is also a lot of SACD released in Japan, like at CDJapan.co.jp, but they are expensive.
