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.

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? sfz_professional.rar
