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

The problem of hiss is NOT your krell amp,  but rather your front end,  I  had the same issue once with an ayon cd2s player,  none before or after every heard a hiss from my krell 700cx,  and I always run directly to amplification.

Hi lalitx, interesting,  mmm, do you have shielded and RFI/EMI  interconnect's such as taralab's cable's? , my interconnect's have an out board station that has it's own ground to  component's or connect to whatever earth ground, I hear no hiss ever.
