Based on this criteria, have you heard
Fujitsu Eclipse speakers? The TD712z have been consistently good when I've heard them at Hi-Fi shows, but they don't come up too often second hand. But the TD510 and TD508 come up on ebay fairly often and are around the price you paid for the Klipsch. I fell in love with the Eclipse sound when I bought a paid of TD508s via this forum. They have now been supplanted by a pair of TD512 and I love them.
