I'm must be confused then, looks like he's selling them but also looking for a good amp to pair with them?
Anyway, Louis gave me a pair of Super 3 HO XRS to play with prior to ordering mine. I kind of had a love hate relationship with them. With some music they were simply stunning....best I've ever heard, and others not really to my liking. I tried a Class A Threshold, Prima Luna tube and a Parasound amp. That's just me and my ears, not saying they weren't great! I still took a leap of faith in him and ordered my Modern CAMs and absolutely love them...on everything.
I guess my point is if amp pairing is proving to be frustrating it may just be that speaker. Another of his models might just be the perfect match for you like it was for me.
