In Reply to: I read an article in the absolute sound many years ago that stated many components are being designed with CDs in mind. posted by Teresa on May 18, 2006 at 16:41:02:
It's clear measuring many high end players that they deliberately roll off high frequencies earlier than 22.05kHz.On some players, I have measured a roll off as early as 12-15kHz and down -3dB at 18-20kHz.
Perhaps this is an attempt to "tame" the "harsh" sound of CDs, or a desire to have better overall filter performance.
But I would prefer a flatter response (I don't mind -1dB at 20kHz, that's what my current player does).
If the intent is to tame the harshness, then I would suggest a much better way of making CD high frequencies sound better is to reduce jitter (preferably down to the picoseconds, which is not possible on many players due to PLL).
