Say, has anyone else noticed that the most stereo / surround receivers only output a max of 20khz, yet we're led to believe that we're getting otherwise because of a sampling rate delusion?

I think in most cases, for audio, 20khz is considered the practical upper limit of  hearing.

That's pretty much been the case as long as I've been around.

Correct, our top end hearing range limits way below 20KHz as we age, but with modern digital sound systems the DAC's samples way above. The higher the sampling rate, the better sound definition and subtle detail of clarity is perceived in our music listening pleasure. Isn't modern tech wonderful.  Merv

Merv,

I first ran into 'sampling' from an old PAIA kit I built back in the '70s. I think the rule of thumb was to sample at something like four times the high-end it was expected to process.

Digital is pretty cool, you can emphasize sub-harmonics of the frequencies that might be out of range to psycho-acoustically augment 'perception' of clean highs.

And of course, no more noise-reduction hassles with digital.

Still, there's something about tube-amps and vinyl...
