I don't know from personal experience, but, it's reputed that speakers hooked up to digital amps don't demonstrate this propensity for ear to tweeter hiss.
Noise from tweeter
I am using Aerial 7B's drivin by a ML 333.5 amp from a Theta Casa Nova and a Sony DVP 7700, I am using Kimber Monacle XL to Aerial's, Kimber Hero interconnects from Sony and Kimber Hero balanced to ML. When I put my ear to the tweeters I can here noise, even when evrything but the amp is turned off. The amp is plugged into a dedicated 20 amp circuit. Note: I had the same problem with the Classe' CA 400 I was using before. Thanks in advance, Henry
