Upgrading from Primaluna

About room acoustics, with a room only 15' deep, you need some corner bass traps and a lot of diffusers in the back third of the room since you likely have very little space behind your listening position. I agree 100% with the posters emphasizing the need to work with your room and equipment placement first. A sure way to waste less money down the road in fruitless equipment upgrades. Take a look at my room setup. Enjoy the journey.

I went down the high power road for a while.  I had my own personal room heater with 4x 6c33c tubes.  Now with my efficient speakers I'm running 6 wpc of decware and much better sound, my amp makes less heat than my TV, and I can listen or use it for my 2 front channels of AV all day long.  Highly recommend Decware.

With the BHK the world speaker selection is your Oyster!

For 2k more I would get 2 PL Evo 400 amps and mono block. If the El34 tubes aren't enough power you can always get KT150 tubes. Don't give up the tubes because of a little heat. I run them in my basement system. 

Your speakers look too close together.  I wish I knew why some like tube amplifiers over solid state?  Seems to me, people with tube amplifiers are always buying tubes.  I also prefer to put my gear into an enclosed entertainment cabinet so it looks nice in a nicely furnished living room.
