Wow, that's a long thread. I think I'll have a look through it tomorrow. The Kanex Pro seems an interesting device and at $56 on Amazon at the moment is very reasonably priced. Ideally it would be great if I could have all my disks ripped properly but maybe this is the next best solution? Are you using one of the old PS3s to extract DSD from your SACDs?
I would steer clear of the Kanex since it doesn't support 24bits. I think Ted_b found a better unit that doesn't truncate the signal.
