What I'm after (and have now got) is a system that enables me to listen, with enjoyment, to an ever-wider range of music; that can 'do' everything from dub to punk to jazz, and from solo piano to full-scale orchestral music.

Is the system 'faithful' to the original sound? I don't know and don't particularly care. What I'm glad to have moved on from is a 'listening for differences' state of mind, aka 'audio nervosa'.
