Folks, Thanks for all the input. Pardon my ignorance but I'm not sure what shorting plugs are. Are they the interconnects between the amp and pre-amp? I will try some of the things suggested to see if the hiss is the amp or pre-amp. In answer to a previous question, I don't have gain control on my amp so I'm stuck with what I've got.

Hello, I have a pair of Klipschorns (1989 ) that are being run by Adcom components (GFP-565 preamp and GFA-545II high current amp which is rated at 100 w rms). Speaker cable is high end Kimber. This combo sounds very good except for the idle hiss when no music is being played. I suspect that this is due to the high efficiency of the speakers.?.? My question is, is there a better match for the Klipschorns in terms of a amp/pre-amp combo that sounds good and is more quiet during idle? I love the sound with the combo that I have now but the idle hiss is getting very annoying. I would also like to know what others are using for the amp/pre-amp components with the Klipschorns with great success... Any input would be appreciated...
