I looking at Usher Tiny Dancer One, power?

That should drive them nicely.

no problem with too much power?

I'm assuming you mean the Mini Dancer One. Don't look at the power ratings. They can handle plenty of power. 250W is a very nice match for the Mini Dancer One. In my opinion, it is a superior speaker to the BE-718, but the improvements are certainly not dramatic. Since you already have the BE-718, I personally don't think it would be worthwhile to move up to the Mini Dancer One for the small improvements.

Thanks Everest, good to have that info... the Dancer one has the dmd... is there a big difference between dmd and berryllium ? Don
