amp for Usher speakers

I've heard the 718's at a local dealer with a variety of amps.I really liked the way that they sounded with several medium powered tube amps(including a 50wpc Raysonic KT-88 integrated,Soundquest SQ-88 integrated and a pair of Granite Audio 30wpc SET monoblocks).

I owned BE-20's and for fun I tried an Ayre integrated on them. I'll tell you that was an excellent combination. If it drove teh BE-20's I'm pretty sure it will have no trouble with 718's.

I'd like to hear ushers on a good Class D amp, like Wyred4sound perhaps.

I've only heard the Ushers on a good tube amp system and they sounded a tad thin and shrill on that in comparison to others. I think SS is a better choice and the Class Ds specifically are known to have an easy top end in general compared to some SS amps.
