Speaker Hiss with Krell Amp

Hi,

I have an in home audition with a Krell Evolution 302 and there is a hiss coming from the speakers. This did not occur with in home auditions of Hegel H20, Proceed HPA 2, Levinson 533, or Pass X350 amps.

The Krell is the only one of the tested amps that required a 20 amp cord. All of the amps were run on a 15 amp dedicated circuit. Speakers Are Thiel CS 5's with a Prima Luna Dialogue Premium Preamp.

Can anyone explain what is going on?

Thanks,

Scott

Do you hear the hiss with only the Krell amp in the chain? If not the cables it could be a pre or source. To me if the hiss is common in an amp of that caliber I would pass on it especially if a super low noise floor is what you're after. With either an Octave V70se/V100 I had absolutely no noise unlike my Bryston (low hum). Now I have an Aavik U300 and still no noise at all.
Just my opinion and best of luck.
