Had a look at the effect on the ASUS Essence One which has a "symettric
upsampling" feature. So 44.1kHz material is upsampled 8x to 352.8kHz.
No upsampling - square wave, 0dBFS, 1.00227 kHz:
14787
With 8x upsampling - square wave, 0dBFS, 1.00227 kHz:
14788
Nice :-)
Harmonics remain clean and I

Yup. And since we're upsampling, the duration of that sample period is
even briefer.

I was just discussing this with a friend, who's a qualified electrical

And even if you hit that very special +11 dB beas
