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.

If you want to stretch it a bit and go the used route, Ascend Sierra2's come up at around $800 A pair.
A custom SEAS driver and RAAL ribbon tweeter, bamboo cabinet.
A true, terrific sounding bargain.
Having owned both Triangle and Ascend speakers, I would say the former are more detailed while the latter punch a bit heavier. Neither is better or worse - just a matter of taste.

However, the Sierras are harder to drive, measuring 86db compared to the Triangle's more current friendly 92db. Frankly, I'd be more comfortable with floorstanders.
Welcome to you.
I have a Sierra for a center channel. It works great with an AVR. Front level is set at -5 so it seems plenty efficient with Janszen’s front and Martin Logan’s in back.
If course trying both is the only way to know what’s better for your lifestyle.
Good luck finding happiness.

I am surprised to hear the Triangles are more detailed. My uneducated assumptions would think Ascend would be more focused on detail. 

And yes, floor standing is attractive, but I'm game either way. I did read some numbers about the impedance dropping into the 3s in the BR08S though.
