I think Pass should stick to electronics, and not veer off into engineering that he obviously does not understand, or at least, goes out of his way to ignore. The changes in air pressure that are caused by sound are extremely small, unless we're talking about canon shots. Hence, these ideas about pushing air or creating vacuums is just a bunch of nonsense used to sell more expensive whatever. You guys know that sound travels through water right? Water is essentially incompressible, yet you still hear sound through it. Just think about that, get an engineering PhD like I have, and then tell me if you still believe thin non-linearity of air crap. -- ezkcdude SB3->Derek Shek TDA1543/CS8412 NOS DAC->MIT Terminator 2 interconnects->Endler Audio 24-step Attenuators (RCA-direct)->Parasound Halo A23 125W/ch amplifier->Speltz anti-cables->DIY 2-ways + Dayton Titanic 10" subwoofer He's not hi-fi, he's my stereo. ------------------------------------------------------------------------ ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=22118 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
