Sweet new tube amp needs better speakers


I am trying to move up from my old Martin Logan 40"s. I recently bought a Cayin CS-55a  30 watt Integrated tube amp. It sounds really good with EL34s or the KT88s. I bought a pair of Triangle Borea Br-03 bookshelf speakers (under $500 / pair) and was Wowed by the improvement in sound. Now I want to move up. My goal is to upgrade to a set of speakers in the $2000 to $4000 price range. they should be floor standers under 43 inches tall and with a sensitivity of over 90db. I don't want them to be excessively bright and I don't plan on using a subwoofer.. We mostly listen to blues, rock and roots music (African, Brazilian  and Middle Eastern). My room is about 14 by 20 and open on the short side to the kitchen. I have been looking at Teckton Perfect Set 2- 10, Zu Omen MK II. Kef Q-950, ProAc DT-8 and the Triangle BR-09 and Gaia EZ. 

thank you in advance for any feedback and suggestions 
Tectons are 3 months out
Zu's out of stock

Thank you for explaining the sound of the Zu. I was considering them because I really love the way they look. I think I will back off from the Zu and get the Triangles or wait for a Tekton Perfect Set 2-10. Unless I can find some used DeVores.

Yes, the Response DT8 is what I was referring to.  I think you'd be happy with me.  Much more refined than some of the other options you're considering.
Crites Speaker.  Look and size of Klipsch Cornwall.  Make yourself or premade in unfinished birch.  Bass down to 35 Hz or so.  But I use a couple subs.  Selenium tweeter update.  About 2000 to your door.  They have a live accurate sound with nice punch if needed.  Sound good at lower volumes.  Some will say mid range coloration due to no bracing in cabinets but they don't cost 10k either.  ALK makes a different crossover if preferred. 

I clear coated mine.  My wife likes them without the grills. 

PI makes another DIY or assembled.  Cost varies with options but less than 2500.

I read that they are cool sounding, but I also read they had good base. I will get some more reviews . I'm not sure how to connect a sub to the amp, it doesn't have a sub output. I think there is a way to connect them with the speakers.?

So many members have recommended these. I know they are great speakers. The problem is that they are 25 inches wide and our gear would be behind them. I think it will be too crowded our room.
