There are a number of rules in the audio world that haven't held up. For long time it was considered that we could only hear differences of at least 1 dB. That has been demonstrated to not be correct. I remember reading about a double blind test in Stereo Review that went bad because there was a .1 dB diffenence in levels. The listeners could pick it up. Bell Labs was able to show that filtering out everything above 30 KHz was detectable by a person who was tone deaf above 10 KHz. Jim Smith in his book "Get Better Sound" has a great story about discovering that he could pick out sounds that were below the noise floor in analog recordings but not in a digital recording of the same. The human ear is pretty amazing.
The naysayers about cables always claim that only resistance and reactance count. We in the wireless industry are being increasingly plagued by a distortion called PIM, which occurs in cables and connectors. It is every bit as possible in the audio range as the microwave. And no one except maybe a specially built research lab can measure PIM in the audio frequency range. We only recently have developed the ability to measure it easily in the microwave range, which is orders of magnitude easier. If people are consistently hearing differences even though the theory or instruments say they shouldn't we should assume it is always a case of self delusion. We knowledge is dwarfed by our ignorance. -- regalma1 ------------------------------------------------------------------------ regalma1's Profile: http://forums.slimdevices.com/member.php?userid=6658 View this thread: http://forums.slimdevices.com/showthread.php?t=93483 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
