Yep, that was 20 on the iRiver, in addition to the pre gain. When I turned it on it was at +20 and I was in a rush (no pun intended) and it did not appear to be clipping so I left it alone, thinking that the AGC (or whatever it *should* be called) would kick in if needed. I thought that was a lot of gain but it was not clipping, so....
One thing I've wondered is if the 1 second threshold on the AGC allowed some distortion to "slip through" without activating the AGC. The distortion is of pretty short duration, but is pretty pervasive throughout.
