Yea I was looking into the PS3 to rip my SACD. I have the correct model, but the firmware is 3.7. Downgrading the firmware can be done, but is a pain. I have a program that will pull audio tracks from Blu-Rays. Some emersion packs have Blu-Rays that contain a 2 channel HD version of the album (Dark Side of the Moon). I am not promoting hacking, but I have some SACD I can't play and if I ever drop $120 on an emersion pack, I consider moving the audio from the disc to my computer fair game.
I have bought some HD music here: https://www.hdtracks.com/index.php
I have just built a tiny computer that plays HD music (ATV2 before). Dac tops out at 96/24, but my upgrade should be here Tuesday and let me enter the 192/24 world. Thanks Bob, very interesting.
