Oh, that's a totally different set of nightmares. There was a recent
JAES paper on downsampling that you might want to look at.

The thing is, you have ultrasonic audibility issues, you have sample
rate conversion artifacts. You have converter artifacts, which are
different at different rates. The confounding variables are many.

The advice I need is, should I:

1-Start with a 192khz source, downsample it and play it back at the
downsampled rates on the D to A converter

If there are artifacts with downsampling, you'll hear differences. If
there is ultrasonic perception going on, you'll hear differences.
If there are differences due to converter artifacts, you'll hear
differences.

2-Start with a 192khz source, downsample it and play it back at the highest
rate on the D to A converter

This eliminates differences due to converter artifacts changing with the
data rate but leaves the others.

3-Record the same performance at different sample rates and then play it
back at its native sample rate

This eliminates differences due to sample rate conversion artifacts but
leaves the others.
