I would like to inlist the help of all you knowledgable Klipsch owners in buying the best mid-priced SS amp and pre amp set up for my new set of Fortes. My budget is $500 to $750 for both the pre and power amps in the used market. I have read about Adcom being harsh in the highs and not well matched to Klipsch while others like the newer Adcom MOSFET designs such as the 5000 series power amps. My brother loved his Adcom 535 II with his Fortes. He also used an Adcom pre. I have also read glowing reports about B&K for Fortes in this forum. I would like recomendations on specific brands and models. I'm running the Fortes currently with a Nakamichi 610 pre and a Phase Linear 200 power amp and they sound much smoother that with the Sony ES receiver with which I have experimented. Thanks for the help. George
