any info on musical fidelity nu-vista m3

I am looking at purchasing this intergrated amp to drive my nautilus 804's with a Linn genki cd player. Currently the amp is the Linn lk140 and pre amp is the Linn wakonda. Any opinions regarding the above integrated or other separates in the nu-vista's price range or possibly $2,000 more. I want to maintain some of the warmth of the Linn system, but want more bottom end and soundstaging.
thanks.
