Flac 8 does take marginally more than 5 to decode... and both take a lot less to decode than they took to encode (that's the asymmetric bit). There's some facts about this somewhere on the Net... :-) The truly paranoid would of course downsample their hi-res files to 24/44.1 to minimise Touch CPU activity... :-) -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
