I dunno. I'm far from an audiophile. I listen to stuff on a cheap android MP3 player, a cheap Android car unit and a 30 year old Yamaha stereo. It's a long time since I was in a studio to hear studio quality and I doubt my hearing these days would be good enough to do studios justice anyway.
I've got the original RIP master tapes (all lossless recordings), each track, guitar, drums, bass, lead guitar, lead vox, backing vox all separate files and sure I can hear a difference between those and the CD but I'm not convinced it's better. Thousands of others would be, some probably just because they are told it's the tracks straight off the desk, but hearing is such an individual thing and just because I don't think the studio master is better doesn't make me wrong, just different.
