Ascend Sierra 1 vs Triangle Borea BR08


I decided to upgrade my current bookshelf speakers (Infinity R162s). I've settled on 2 options based on some reviews: 

  • Ascend Sierra 1 (on sale for 680/ pair) 
  • Triangle Borea BR08 (on sale for 800/ pair) 
I'm newer to audio stuff, but I felt it was a good time to upgrade. My current system and listening area: 

  • Denon AVR-X2600H (95WPC) 
  • HSU VTF2 MK5 
  • Fluance RT-85 (Nagaoka MP150) 
  • Art DJ Pre II (12V power supply upgrade) 
  • 24'x15' living/dining area with 9' ceilings
  • Not treated and can't be because WAF
  • Opening to kitchen and staircase 
  • Listening Position about 7-8 feet from speakers currently
Originally I thought the Triangle might fill the space better and I like that is 3-way. That said I've heard some middling reviews about response.

Sierra 1s are at a great price, and I would assume better quality. What I'm concerned about is achieving adequate volume in the space.

I value accuracy above volume, but I don't want it to sound anemic in space. I will probably end up just trying both and judging for myself, but curious as to your opinions. 

Thanks! This is my first post here.

Ascend is local to me and that's attractive. I have heard great things about, Dave, the owner as well. 

Ascend also offers an upgrade kit that takes the 1s to the 2-EX and shaves a few hundred off the price. So that's also attractive.

Truth be told, I ordered the Triangles a couple days ago because I figured the deal would be dead. Found them on Adorama thru slickdeals. Looks like back to 1200-1400/pair. 
Man, you scored.  I was strongly considering the Bro 3 a while back.  I don’t think you could have even done better buying used.  
Enjoy your new speakers!
