what do i power my thiel 3.6 with

Hi all,
Let me start by saying that I do not yet own the speakers. I have a chance to purchase a set of Thiel cs 3.6, in mint condition from a good friend of mine who inherited them. I was not familiar with this speaker until he messaged me. I have always been a paradigm guy. he is asking for 1000 bucks Canadian, so my first question is whether or not this is something I should jump on... based on reviews, I’m going to guess that it’s a good deal.... if I go ahead with the purchase, my big question would be what do I build around them... I have read a lot about these speakers needing a lot of power, and the amp I have now, will not do the trick... it does not even really power my studio series paradigms as is. I would likely get rid of everything I currently have (unless someone suggest otherwise) current setup is studio 80 fronts, studio cc590 center, adp rears and dual pdr 12's powered by a Yamaha rx-v2400 home theatre receiver. any advice would be appreciated, and when replying, you will have to dummy things down for me... I’m big into sound and love music, mostly live concerts is what I watch, but also appreciate a good surround sound for movies. That being said, I am by no means a sound expert, and have only ever dealt with home theatre and stereo receivers. I’m sure a lot of the suggestions are going to be about tube amps and pre amps and such, if you could explain that to me it would be very helpful! Thanks in advance
