Simaudio Moon 740P preamp vs. Ayre KX-5 Twenty

Anybody compared this to Ayre KX-5 Twenty? I really like the Ayre, but I can get a Demo Moon 740P for about $5K locally.

Any other solid state preamp that I should really look at ? I don't like tubes preamps, unless something "hybrid" like PS Audio BHK Signature Preamp.

Thanks!
