Hi ‘ m a newbie… I have opportunity to buy a pair of Kp 301 original made in 1988. They have new caps and everything else is supposed to work fine. I can use advice from this great group on the following: Does $850 seem like a good price? Would a Denon avr with 125w per channel power this well? (X4500H) Finally if I converted the back panel to a 5 way post and wired for bi amp, would like reduce the resale value? Attaching a picture. I have not listened, but would be buying from a guy that says the sounds good, and he currently also owns la scalas. Says they have been recapped, and sound great Thanks!
