I own a pair of older quicksilver M60 monoblock amps which are heavily modified, using EL34s. My current speakers are Eminent Technology LFT - at 83db they are incompatible with the amps. Mike Sanders at quicksilver recommended Klipsch's as a perfect match. I usually buy used and my budget is 3,000 give or take and my room is 14 X10. Any recommendations? Many thanks!
