The Emperor's New Sample Rate

I don't think you can make that leap. Lots of CD content rolls off above 20kHz, while some encoders keep everything up to about 19kHz, so the loss is tiny. The loss of 22-48kHz is huge in comparison. I'm not saying it's audible - I'm saying your argument is not safe. Good point, agreed. However, i guess you'd agree that if we had testing-material with significant content up to 22khz, speakers capable of reproducing it, and then ABX it against a 18khz-lowpassed version... that the results then do have some significance? Its no safe proof, right... but in that case, its weight would be significant, no? And its something which is much easier to test than signals >22khz, right?IIRC there was one individual who could ABX a 19kHz low pass filter. This was back in the r3mix forum days, so you won't find the post on HA. I think i remember hearing about him a few years ago already. I definatelly do not envy him.the fact that i can hear the highest frequency available on CDs is a bit unsettling. I find that statement quite unsettling as well, partially because most playback equipment isn't even capable of reproducing the full 22khz range.why not go the extra mile here and cover all frequencies audible to even the golden ears. Perhaps because until today, every single one of those "golden ears" failed to ABX what they can hear "easily". There isn't even one single valid and successfull >22khz DBT - nothing, zero. It is off course not impossible that you are an exception, but i guess you can understand why such stats make people suspicious unless the person can show that placebo can be excluded.
