This is a problem? I can't believe anything is needed above 50k. But there does seem to be something happening in PCM that is not happening in DSD. |
first the 50khz lpf is after the signal has been converted back to analog. philips says it is to protect speakers that might have not been designed to handle transients over 100khz.
as for having an impact on the quality of the the sound iam hearing from more people that it dose. basicly what ive been hearing, and this is vary new to me as in the last couple of days, is that your brain dose not percieve transients with frequencies over say 20khz as sound but that it will use them in determinig direction and distance. there for the impact would be found in the percivied clarity of the stereo image and depth of a recording. but like i said iam just learning about this recently. one day we might try some test on this if we have time.
sorry for the vary sloppy post eariler. i need to not respond to post at 2:30 in the morning.
