This is some quick REW measurements of UAD Apollo Twin Duo thunderbolt interface (this is for Mk I. Mk II has somewhat better specs reported by UAD).

The interface was measured in loop-back mode, with line output being fed into the instrument input.

1.434v on line out, 1kHz @ 44.1k/24bit sine wave generated by REW:

Multi-tone test (1/3 octave, white noise):

Jitter, 12kHz signal:

And finally, a frequency sweep at 96kHz sampling rate, also showing a very flat phase response (lower trace):
