Pre and power amp for Vandersteen 3A Signature?

Vandersteen 3 A Signature is one of the main contenders that I'm considering now for my rather large living room. For stereo as well as HT purposes. I know that Audio Research is the ideal amp for them but I would prefer solid state pre-power amp combo and of course preamp must have the HT bypass. My main concern with Vandies is PRAT and dynamics. Nobody doubts their incredible musicality but I want them to sound fast and tight when necessary (be it heavy metal or movies) and deliver the best bass they can as well as the most explosive dynamics they are capable of (I'll have almost 4 meters between my ears and the speakers). I know Krell is a good choice. What do you guys suggest?
