The only spec I found on the Digi site:
Per measurements on an Audio Precision Cascade-2 the frequency band-edge measurements:
192 I/O @ 192 kHz
Frequency Response: - 0.2 dB @ 50 kHz, - 2.0 dB @ 88 kHz
192 I/O @ 96 kHz
Frequency Response: - 0.2 dB @ 38 kHz, - 2.0 dB @ 44 kHz.

I have the sinking feeling that while some units will sample at higher rates, they do not have a wider frequency response. Therefore, why bother?

Well, you just gave examples of units that will do the job. As always, my suggestion is research before you buy. Don't buy a 96kHz converter with a 20kHz frequency limit.
Again, thanks for the great post!
