Amp for Shahinian Obelisks?

the shahinians are big ss all the way, but aren't what you would call an ideal speaker for rock and roll or electronica....

its a classical music thing. they throw a big as life soundstage without sacrificing weight. though different than a bose 901 or an allison 1,2, or 4, or a gradient revolution, or the klipsch legacy designs,the speaker uses the room it is in to full effect. a music lover's speaker- not an audiophile speaker. like the others mentioned, its generally purchased by those wanting off the merry-go-round.
