Which amp for B&W 802 Matrix series 3

I am primarily playing vinyl on my system and sometimes CD's, looking to upgrade my TT and get into an MC cartridge. I am currently driving my system with a pair of NAD 2200's and an ARC SP-4 pre-amp. I was considering a pair of ARC M100's as my first tube set, have not found any opinions on how this might mix with the B&W's. Is it a mistake not sticking with solid state? I have considered Classe solid state as well, but the vinyl bug has bit me.
