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

dsper,

Have you tried just running the amp with no input (or shorting plugs)?
With no signal applied, does the volume setting on your preamp change the results?

It might be a grounding issue.
