I looked around a bit and found this interesting article: "We can see why statistics often "mislead". LP's noise floor is actually quite low over most of the spectrum, ranging from -84dB around 1kHz to -96dB for frequencies above 10kHz . In other words, *the LP recording has a lower noise floor than the CD recording for the majority of the spectrum* (frequencies above 2kHz )." http://www.audioholics.com/techtips/specsformats/LPvsCDformats2.php Considering this and the ability to listen way down below the noise floor (since it is uncorrelated noise) LP may surprise. These figures actually fit a lot better with the actual LP listening experience than the simlified overall S/N figures. -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=21836 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
