You have nailed it!
Any good tube amp with 4 tubes per channel rated at 60-80 wpc into 8 Ohms would prolly suffice. I have used a small older McIntosh SS stereo power amp with great success with 50wpc. he Macs and Klipsch synergize well. I am otherwise a tube devotee. Can you buy Chinese because I really like my Opera Consonance Cyber 800 monoblocks. Quest for Sound has them he is an Agon dealer.I think you really do need substantial power to drive the woofers. You have to compete with the supersentive squawker. I have the same drivers in La Scalas. If you can, you might want to get the X-overs modded as well to give the speakers the best tonal balance. Bob Crites X-overs for instance, check out the Klipsch forums for details and discussion. I avoid subs but that's my preference.
