Which speakers for Hegel H20?

I know that, ideally, you are supposed to match your amplifier to your speakers. Well, this time it's the other way around. I own a Hegel H20 amplifier. Dual mono, 200 Wpc into 8 Ohm, 350 Wpc into 4 Ohm. After selling my Tannoy Revolution XT8F speakers a few months ago, I am presently looking for a  good pair of speakers to match to my Hegel.  Budget: $7,000 or so. 
I am looking at Spendor D7, Proac D30, Dynaudio Contour 30 but I have no way of knowing whether they will work well with the Hegel.
Advice would be highly appreciated.
Thank you!
I have heard Hegel amps (various models up to the H30) with KEF Blade speakers. A used KEF Reference 3 or Reference 1 would get you great sound. 

However, I also think the speakers you have listed would have no issue ( I have not heard Proac). That Spendor D7 which I heard at my friends house with Audio Research amps was rather good.

The big Ushers, be20dmd's and earlier revels for sure. Most dealers will let you bring your own amp in if they know you're serious.
