I have a Denon 3802 and rf7 rc7 rs7 and have no hiss,source is likely suspect at high volume.Also as noted,these speakers are very revealing.See/listen if hiss is audible at first vol step,and I dont mean stick your ear into the speaker,all will have some small hint of sound.If you step back 1 ft and hear hiss,at lowest vol.you have defect/wireing.I had an onkyo 777,while it sounded ok, it hissed like a snake,to fix they installed filter,I don't like my music filtered,thus I gave to son,he loves it.Denon sounds like no hiss after that,and much more musical.While I like pearl jam, their recordings are not perfect,the 4 I have poorly recorded,try STEELY DAN, two against nature,its clean as it gets!
