Out of curiosity what do you guys use as standard? I know (from listening experience and from a TC Electronic paper) that a lot of consumer cd players will additionally clip the signal beyond 0dBFS when D/A'ing and things are so hot. In which case I suspect -0.3 instead of 0dBFS doesn't make any difference - probably should be at least -3dB or something.. But in other respects, there could be a difference in 0dBFS or -0.1dBFS peak level, I remember reading something about mp3 conversions generally not liking anything hotter than -0.1 or -0.2 (Bob Katz)? Most commercial cd's tend to be either 0dBFS or -0.1dBFS (pop/rock/dance) so obviously these facts are mostly ignored in the loudness race (in which I "happily" participate myself).
