I wonder if we are ever going to have one standard for hi res! I've heard some of my familiar music in he res, and it sounds amazing, more detail etc. Thing is, one of my favourite artists has blu Ray audio, with several versions of the same album (5.1 Dolby, then 24 bit stereo. Even a quad mix!) Others artists have released flac, etc etc. Pure audio is another, and I've seen other types. How many times do I have to replace my CD collection? I've already been through format wars, vhs, betamax, hd DVD, blu Ray, mini disc, omg !!!!
