i greatly agree with those who mentioned various models of pass labs amps. the xa series may result in a bit warmer sound within the neutral spectrum. there is also the new xa.5 versions; i am unfamiliar with them. if you consider pass for the amp, you need to be aware that synergy with a variety of tube pre's may be an issue with impedence. also, pass amps should be run in balanced mode for best results, which will reduce some single ended preamp candidates.
if in a large room with moderate db levels, probably the x350.5 would be the smallest single amp for either sophia2 or w/p 7s or 8s, though the xa100 does produce 100wpc all in class A. i suggest you speak directly to pass labs if you are considering them. many of their customers have wilsons.
vtl and arc make excellent tube amps + excellent pre's to mate. if the room is large, i think you need to go above the arc 110 amp if pairing with the w/p 8s or you may lack tight control over the bass range IMO.
careful cable choice is important with the wilsons. they are very revealing speakers.
