I've enjoyed reading this thread. I jumped into the Thiel world several months ago when a pair of CS 1.2's popped up locally. Up until then I had been trying a variety of vintage speakers including Ohm Walsh 1, Original Large Advents, B&O RL 140, Avid 330, Cerwin Vegas, etc. When I listened to the Thiel's, I was hooked. My plan was to eventually work my way up the Thiel food chain. About 3 weeks ago a pair of 1.5's popped up, so after conferring with Rob Gillum, I figured I would have an incremental improvement over the 1.2's. And there was. So I retired my vintage Dynaco ST 150 amp and bought a new Yamaha A-S701. All was good, was loving the combo, when a pair of 3.5's popped up somewhat locally for a good price. They came with the original boxes and the eq, so I bought them. But my Yamaha doesn't have a pre-out or loop for the eq, so fortunately I was within my 15 day return period and back it went. I ordered a Peachtree Nova 150. It should be here in 2-3 weeks. In the interim, the honking 3.5's are being powered by a vintage Kenwood KA-5700 integrated I had in the basement. Can't wait to feed them some real power and see how they sing.
