BHK 300 and speaker hiss

Hello. I’m in Day 3 of having new BHK 300’s (~45hrs run-in so far) that may replace my VTL MB-450 Signature amps. I have a hiss coming from my speakers that I didn’t have with the VTL’s. It’s loud enough that when seated in the listening position, and it is audible when no music is playing. I had read in one of the reviews that these were supposed to be dead quiet. Have any 300 owners had the same issue? Possible fixes? Thanks, David
