Which Amp will make the802N sing

I just took delivery of a pair of Nautilus 802's which do not match any equipment I presently own. I started about a year ago, not anticipating catching the bug, With Arcam FMJ integrated and power amp's, sourcing from FMJ tuner and DAC, runing into 804N's via Straight wire Maistro. I've considered from reading only, the Audio Research LS25 pre with the VT200amp and less bright Cardas cable. Has anyone heard this system or have any thoughts . Looking for a natural presentation which is detailed and tight from top to bottom with a wide and 3 dimentional sound stage. Thank you for the feedback..
