What dynamic spkr. did you go to from electrostat?

I currently own a pair of ML Summits but considering a dynamic speaker which might offer more impact, however I am not wanting to part with the exceptional mids & highs that a good electrostat brings to the table.

Which dynamic speakers seem to offer the "best of both worlds" out there?

Also am wanting to stick with tube amplification, so has to be something that is decent to drive.

Thanks.
