I'm always amazed when folks talk about differences in the 120 dB or larger world. As opaq' says, you just can't hear that. And no person has an 'absolutely silent room' [sound is never absolute anything, be definition dB is relative, but I grok what opaq' is meaning. I know of two silent rooms in Virginia. There may be a couple more, but I doubt it. One is in the Acoustics Department of the Mechanical Engineering Department at VA Tech, the second is in a lab at a major defense contractor. I've been in both, and the are really weird. Humans do not like that 'much' silence. Any discussion of difference down 120dB or more are snake oil. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
