Conrad Johnson Premier 140 + Magneplanar 3.7i

Because of environmental concerns, I'm thinking of replacing my Wilson Sophia II with Magneplanar 3.7i.
They should be controlled, like the Sophia, the final valve Conrad Johnson Premier 140 (140w p / c with 8 GE Jan 6550 Green Logo).
Since I have the chance to hear them together, I wonder if this can be a happy or not marriage.
The listening room is mt. 5 x 8 x 2.92 (+ or -).
Opinions / advice on this?
I think the combination should work well together.
The preamp could be a key factor in this senarido.
