does anyone know how this sounds

I don't
Have it hooked up yet but planning on making the buy.
2 Cambridge 851w amps, a 751r as a pre amp,
4 kef,r900's, 2 kef r400b's. Does anyone have this configuration and if so how does it sound.
Probably like a good stereo should. I don't own any of your equipment but have heard the KEF900s and they did sound nice.

All the best,
