Best sub 4000 dollar standmount.

I'm in the market for a standmount with a big sound that can work in a samller room yet have a big enough sound for a larger one too. I have amps with plenty of power. A musical Fidelity KW550 and a Krell Kav 400xi also.

I'm particularly interested in The Usher 718be and how it compares specifically to the Sonus Faber Auditor M, Dynaudio Contour S1.4 and possibly the Proac D2.

Any opinions greatly appreciated.
