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

Well Stereo5 that is what I am thinking given all the info about noise floor and retrieval of low level detail not to mention something could be wrong with it.

I also know that there are not connectors between the XLR pins so Almarg could have this right.

The hiss is audible about three feet away.

Guys, I like my Prima Luna Dialogue Premium preamp which is unbalanced and I really do not want to mess with this problem as the Krell has not reached out and grabbed me to say this is the one.

Thanks for the input!

For the money I guess I need to try a McCormack or Coda unseen and unheard.
