Speakers with a slightly warm midrange


Hi there. I have a Boulder 866 amp which is very neutral sounding and doesn’t add its own character to the sound. I am looking for speakers that will give the system a musical natural  sound with a rich midrange . 
Listening area is about 14 x 17 foot plus there is a big open space on the left that may catch some bass drift. Can you please suggest speakers that may work. Considering the harbeth shl5, tannoy cheviot, Sonus faber nova 2 and electa amator 3. any others to consider?

thankyou

 Many suggestions here that tend toward brightness rather than warmth.

Spendor Classics are yet the best combination of warmth and detail I’ve heard. The midrange is completely effortless and natural with enough detail to keep you engaged and take notice of new information in familiar recordings, yet they don’t highlight the distortion of poor recordings the way a Revel or Focal often can.
 

The cone material used by Spendor seems to have the perfect amount of damping. Voices sound completely natural and present with zero audible ringing and resonance—an issue I believe I can detect even in Harbeth’s vaunted Radial material.

Other brands that get the midrange damping correct are Stirling Broadcast and Graham, which is likely attributable  to their speakers having been designed by Spendor veteran, Derek Hughes.
