I've now started writing up the results of measurements on three different
devices. FWIW The best of these is a Focusrite 2i2. I'll put results on the
web and in a magazine article when done.

However I'd still be interested in other alternative devices. Steinberg
claim that all their 'UR' series *except* the UR22 are USB audio class
compliant. Which is daft from my POV as the UR22 is the only one aimed at
stereo. Anyone use any of their UR range and can comment on them?

Sadly, many makers totally ignore emails, or give a reply which doesn't
answer the questions about class compliance. Guess they don't know ('made
in china' syndrome), or don't care (Windows is the only fruit). :-/

Oh, and measurements show the choice of USB hub+psu can indeed affect
audio performance to a measureable extent.
