Best speaker with tubes?

I am looking for new speakers to use with my Cary V12 tube amp. I run it in 50 watt triode mode. I want a speaker that has great detail with the highs, but can go low when I want to rock the house. I have auditioned Revel, B&W, Thiel, Martin Logan, Wilson and Dynaudio. I am leaning towards the Dynaudio Contour 3.3, but know that I will have to replace the V12 with a much higher powered amp. Please offer your suggestions of speakers I should consider for use with my V12. I am looking to spend less than $10,000.

Thanks.
