Qualifying DACs can be a bad idea if it is part of a scheme that has no reliably perceptible benefits and raises the cost of DACs. Well, its bad to those of us who spend real money on real hardware and aren't like trust fund babies. One of the things that needs to be understood is what kind of performance differences does it take to deliver an audible difference, let alone an audible benefit. For example, a recent AES paper (I cited in a recent post) found the following: 20559 The interpretation of this is that dynamic range improvements above 85 dB have not been found to be audible with any music under any circumstance, and improvements above 70 dB are not audible in most cases. Similarly, improvements that effect response above 18-20 KHz have not been found to be audible with any music under any circumstance, and improvements above 13-14 kHz are not audible in most cases. In both the cases of dynamic range and frequency response, a good clean CD-quality system exceeds or meets the most stringent requirements. MQA does not have reliably perceptible benefits. Obviously, we have pleny of evidence that it does show a benefit in sighted evaluations, but that should be taken as yet another valid condemnation of sighted evaluations for critical decisions like these. +-------------------------------------------------------------------+ |Filename: individual high res audio.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=20559| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=105070 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
