I had the same problem with my belles. A buddy of mine came over one day and bright a vintage Sony receiver that gave the belles new life. I bought the receiver from him as fast as possible. There is something skit vintage receivers that pairs well with vintage klipsch speakers. I just bought a pair of klipschorns. For an initial test I hooked them up to my home theater setup (denon receiver and a Yamaha 120 watts per channel) and they were less than impressive. I then hooked them up to a Lafayette LR-990 receiver from 1977 and they sounde great. I'm picking up a Pioneer sx-1010 tonight to try with them, should be even better.
