All published results I could find show that UAC-2 has 7.7ms under the same conditions.

I have tried Zoom UAC-2 at home on quad core Athlon II 630 2.8GHz with 8GB RAM.  The Zoom had some issues (see my post above) but I could play with overall 5ms latency at 48kHz/64 buffer without any glitches and pops.

For low budget boxes it's worth taking a look on Zoom UAC-2. Don't own any but heard opinions it's among the lowest latency usb interfaces. Note that it's USB3 specifically.

Can confirm that, great low latency interface.  BUT

a) I have got a noticeable more ground noise than from Focusrite Scarlett 2gen. 

b) if you have a PC, be aware about this

"* Only USB host controllers with Intel Chipsets are supported. Operation is not guaranteed when used with USB hubs or expansion cards."

@msmcleod: Yes, you right, it is from rgc audio.  Regarding to this article  http://www.vstplanet.com/News/09/Rgc audio sfz.htm  it should be free for a long time.

I have googled and have found a copy on some Russian server.  Checked with ESET antivirus - It is clean.

So maybe this is what @LadyFuzztail looking for?
