Question: is there a reason that you are going with buffer sizes of
3*2^n rather than 2^n? I've not actually tried what Jamulus does in
that situation (but will do) but it seems a bit strange to me. Does it
have some inherent advantage?
That being said: I was particularly looking for the Presonus Audiobox
USB these days (since I guess Presonus cards newer than the lacklustre
Firebox are supposed to have good preamps/gains) but with regard to
latency, it doesn't seem like the greatest choice.

I recently measured latencies (analog to analog) for some sound cards,
including the Focusrite Scarlett solo 3rd gen (2i2 should be the same):

From all the USB sound cards I tested the Focusrite Scarlett was the one
with the shortest delay.
