Energy Speaker Systems 22 Reference Connoisseur Floorstanding Speakers

I inherited a set of these speakers - the floor standing models that weigh a ton. Anyway, hooking them to my stereo, I get very little power unless I turn it all the way up. Does anyone know what an appropriate amp power would be for these very high...

Own a mint set 80's reference pair. Drive by B&K monoblocks, Rotel pre-amp and Cambridge Audio cd player. I dare to find anything that compares for what a used set goes for.

I own a pair of these and they live up to their reputation. I have yet to hear a better home speaker! There is a pair on eBay right now going for $3,999US and another repaired pair that didn't meet the lowest reserved bid at $180US. Go figure!
