What amp is best with Wilson Sasha DAW speakers


Just received my new Wilson Sasha DAW speakers and am now beginning to sift through a long list of electronics that would bring out the best in them. If anyone owns these and could give some recommendations I love to hear them. I’m open to tube or solid state. Looking for amps and preamp. All opinions are appreciated.

Unless I've missed it I havn't seen an approx. Budget from the OP. Also while the OP has indicated a Signature Sound, which I find really good, they havn't indicated what styles of Music they will listen to. This should really help with recommendations. 
So if you are choosing between VTL 7.5 s3, ARC ref 10, or Spectral 30SV as the preamp with one would you shoes for the Wilson DAWs.  Right now I have a Krell FPB 300c which will be replaced too but preamp first. I have cable systems from Cardas, Transparent and MIT.
