I agree with Esidekid, it would be hard to go wrong with the Krell KSA series in a a system. Even though adding the price of refurbishing these monsters to the initial sale increases their expense, at that price, they still cost a fraction of the new EVO stuff. I prefer the KSA series to the FPB.
what are some of the best amplifiers
I have owned many amplifiers over time. Some were high priced and some were not. My latest finding is a pair of Forte model 7 monoblocks reworked by John Sodderberg. These are very magical amplifiers after 1/2 hour of warm up. The midrange is the best I've heard. Full bodied yet detailed. There is a mystical ring of air and depth that has to be heard to be believed. I have owned Threshold amplifiers(Fortes maker) and feel that the less expensive Fortes(4a and 7's), even in stock form, outperform the Thresholds. I think less is more!
