Hissing sound coming from tweeters

Right now I'm experiencing a hissing noise coming from the tweeters on my Klipsch RF7II's, and can't figure out what is causing the noise. It's almost like a white noise that is there when the amplifiers are powered on and is not affected by changes in volume.

My system consists of an Oppo BDP-83 blu-ray player, Ayre K-5xe preamp, and two Emotiva UPA-1 mono blocks. My cables are Audioquest King Cobra and Audioquest Emeralds. I would greatly appreciate any help resolving this problem. The hissing sound is very annoying. Thanks.

To verify its really the amps, you need to disconnect the interconnect connected to the amps (do so with the amps off of course). If the 'hiss' is still there, then you are hearing the noise floor of the amp's circuit.
Would a conditioner reduce this noise? Maybe, depends on the conditioner.
COuld also be a mismatch between speaker and amps...speakers being too sensitive for your amps.
