Triangle Theta vs. B&W 805D3 with Luxman tube amp

I'm trying to put together a small system for my office, 12x15ft room. 
I auditioned Triangle signature theta with Luxman SQ-N150. The combination sounded good to my ears. 
I'm also tempted to get 805D3 but unable to audition with Luxman tube. I know it is entirely subjective but I was wondering what is a better speaker for this amp? I understand BW is a more recognized brand and would probably keep its value better than triangle. Triangle has a metal tweeter, does It mean it's brighter than diamond tweeter on 805? How do these speakers compare in general? Is 10W Luxman good enough to drive either speaker? 
This system will be mostly used for Vocals and Jazz. I like to play loud, but also has to sound good on low volume at night.  Thoughts?

I would think almost any speaker in the db range of the high 90's and up would work well with the Luxman SQ-N150.
