It completely depends on what is using the digitized data. Let's say I have a simple sine wave of amplitude 1. And sample it at 0, Pi, and 2PI. Then I'll get 0, 0, 0. Now let's increase the sampling rate to 5 samples. 0, pi/2, pi, 3pi/2, 2pi. Then I'll get 0, 1, 0, 1, 0. That is a HUGE difference from basically doubling the sampling rate. Now it is believed that humans can't hear above 20khz so there is no need to go above 40khz. But there is no proof going above 44.1khz is not sensed by humans. This may translate to less fatigue for example by going higher. Not something you can easily pinpoint in A/B testing. I also believe it allows DAC to run better, bass management and other bits of processing to not dip into the 44.1khz realm. Music is analog and it does take an infinite sampling rate to prefectly reproduce it (to capture 100% of the "information"). To the human ear doubling 44.1 to 88.2 may or may not be doubling what the human brain/ears can process and it's impossible to put a figure on it's value to listening pleasure. Is going from 22khz to 44khz twice as good to your listening pleasure. I'd say for most of us it's more than "twice" as good. But we only doubled teh sampling rate. It's not that simple. So there is definitely more information sampling above 44.1 it's arguable if the human brain/ear can use it in a meaningful way. -- mswlogo XP > Cat5 > Transporter > SPDIF > Meridian G68 > DSP6000, DSP5500HC, DSP5000 XP > Cat5 > SB3 > SPDIF > Meridian DSP5000 XP > Cat5 > SB3 > SPDIF > Meridian G91 > DSP5000 'My Transporter Setup' (http://forums.slimdevices.com/showpost.php?p=350741&postcount=45) 'Hitch Hikers Guide to Meridian' (http://www.meridianunplugged.com) ------------------------------------------------------------------------ mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=57413 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
