Thanks, Craig, I'll try to run some tests at home. Fortunately, my listening room has a door to separate it from the rest of the house. And a mic upgrade is in the planning stages already.
FWIW, I ran more sensitive mics (14 mV/Pa) with my UA-5 at last year's fest and had to push the gain to 3-3:30 to get decent levels at a couple of stages. Seemed to be a lot of background noise, though. It was at a quasi-outdoor stage, so maybe the mics were just picking up the sounds of people moving around, etc., and it wasn't the preamp at all.
