From what I've seen in other posts, your volume seems normal to a little low. many people break 50, and a few hit 60. I don't know how high it goes, probably to 80 like pictureguy said. It seems to turn forever because the scale it operates on is linear, not logarithmic(?) which many other receivers are.
