I've owned my pair for almost ten years. I use them now in a home theater set-up with a Sig IVA as the center.
Tubes? Mmmm, I don't know if tubes will give you enough damping to control four 15" drivers. I've used Pass X-150 and Bel Canto Evo II and Ref 1000's with the VI's with great results.
Your room is certainly large enough to enforce the 10 ft listening distance rule needed for Dunlavys to be phase coherent. But they do require a wider spacing than most speakers. Also don't neglect room acoustics. The Dunlavys don't need or want a "live" room. Pay special attention to side wall first-reflection damping.
IMHO the Sig VI's are John Dunlavy's finest and most fully-realized speaker design.
