Kal, my reference is predominantly stereo indeed, multi channel music is never seriously auditioned by me.

I have heard RBCD on Meridian full SpeakerLink gear, also on various (a lot) other high end systems and if the a system is good the result is astonishing.

I have heard playback sources up to 24/192 and I am not convinced that higher bit/upsampling is better than 16/44.1 Yes some specific recordings sound realy nice but that is often unlistenable music (mmm, this sounds as taste, sorry). I do love my upsampled MDMS though!

Maybe this discussion should be about comparing PCM to DSD instead?
