Looking for Speaker Recommendations

The Rockport Avior ii would do very well in the size room you have. Amazing speakers! 

no mention of the so called BBC speakers? If B&W are too bright, Sterling or Harbeth or Rogers might be right

yes they were indeed mentioned early on -- op said he didn’t know what bbc heritage speakers are, are all about, how they sound

if i were him, i would certainly find out, as these speakers have only given generations of music lovers around the world great pleasure for many years

that said, it does seem he has some cosmetic/appearance related considerations, and the best bbc speakers are indeed larger fairly old school boxes...

NSMT 100's!  They have a silk dome tweeter so you don't get the Klipsch/B&W/FOCAL sound on the highs and they are amazing at imaging, depth and tone.  They have a powered woofer so the amp only pushes the mid and tweeter. 93db efficient. I have owned Klipsch, focal, buckhardt and Zu's and these are end game speakers. Made in USA.  Here is Tea Jay's review link.  I have no affiliation at all with NSMT or any dealer so this is my honest listening expereience. I have the black front model with cherry sides.  Amazing speakers. Using a pass labs XA25 amp.  

They might be hard to audition, but if you're near enough to one of their listening rooms, give Legacy Audio a try.  Just the best I've ever hear.  Any of their models, just depends on how much you have to spend.  I own the Classic HDs.  Clear, non-fatiguing, accurate, efficient.  And nice to look at.

What’s your plan for streaming and where are you located? 
 

I’d say Revel Performa F228Be or used Studio2 ?
