At -10 and below, the hiss is definitely better than before. Once you get to a volume of 0, the hiss is getting noticeable. From 0 to +10, the hiss gets LOUD, plus I get some hum and crosstalk from other inputs. This could be due to extra gain on these analog inputs, but I watched a TV show via the analog VCR input, and I wasn't aware that I had to run the volume any lower than normal. If I ever had to turn teh volume up above 0 for an analog input, the hiss/hum is definitely unacceptable.

I have the exact same situation. There are volumes where the hiss is louder than before in a absolute sense, but maybe the gain is higher too.

And there is a definite hum in mine as well that at louder volumes overwhelms the hiss. Please let me know if calibration solves your hiss/hum problems.

I have not calibrated mine and maybe that would solve my problems, too.
