best monitor for tubes?

The contenders are Reference DeCapo, Tyler tylos, and anything else you 'Goners with far more knowledge and experience can provide. I have a tube source and tubed integrated, but am open to experimentation (aren't we all!). Bass extension preferred, too, but I know I can't have it all. Thanks!
Wilson Benesch Arc's - best bass on tubes you'll ever hear in a two way monitor, guaranteed.
Thanks everyone for your input. I am leaning towards the 1sc after further research. I will post an update at an appropriate time.
