Save yourself a fortune and get a luxmam r-117 receiver and use the cd bypass. Plenty of clean, smooth, tube like power and stable to 2 ohms!. If you don't listen to very loud rock/pop or orchestral music try a nakamichi sr-3 stasis receiver. These are out of production but can be found on Audiogon and Ebay. If you must have separates, these speakers really open up with lots of power. There are good reports using innersound amps and rogue tube amps. Good luck with your search..
