Thanks very much, almarg. Yes, the amp is Krell FPB 400cx, and the receiver is Denon AVR X5200. I just looked at the X5200 specs and the only thing I could find that may be relevant is under the Analog section, where it reads:
Rated output: 1.2V

Now, my guess is that that is some sort of nominal output and that it can produce peaks higher than that. Is that normally the case?
With regard to the Jensen adapter, I looked at their web page, and it seems the primary selling point is to eliminate "hum and buzz". I currently have none of either of those, as the system is dead silent until a signal is fed.
