I'm not sure what you mean by absolute amount in ps ... time is continuously moving and so it's only ever relative isn't it? You have to determine what amounts are important to you - it's like noise, what amount of noise is important? It depends on the type of noise because some types and frequencies are less audible and distracting than others. -- Patrick Dixon www.at-tunes.co.uk ------------------------------------------------------------------------ Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=56425 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
