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 end speakers? Suggestions welcome. Thanks.

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!
I bought mine in Canada in 1982 and paid $1,200CAN. The hyperdome tweeter is amazing and the relatively small cabinets (mine have a dark walnut veneer) produce a bottom end of 30Hz (which is exactly what the specs claim). No sub woofer required, although I do have a Sunfire (with 2,700 watt built in amp) for the full bottom end. I power the Energy towers with a vintage McIntosh 2100 power amp and the McIntosh C35 pre amp controls all. This system rocks or whispers and these references speakers make it all work.
