Speakers with a slightly warm midrange

@acdvd 

the 866 is an amazing amp. Did you get the digital side as well? I did with mine and the internal DAC is fantastic. My speakers are Rockport Avior ii and the combination is superb! Incredible detail not analytical or harsh. Good luck!

I would never credit Revel speakers as having a "warm" anything....they strive for neutrality, in a good way.  Sonus Faber is a good brand to consider, but your room opens into a larger area so the models you mention may not have enough cone area to pressurize all that volume.  I would add the Focal Kanta 2 or better, Kanta 3 to your list.  They are warmish and have great clarity and plenty of sock.

Yes i have the digital 866. 
the speakers would be along the long wall and the listening area is at the end of a long room if that helps. So the bass drift would be on the one side but I don’t think too much. 
has anyone tried the Dali epicon or dynaudio heritage special. Not sure if they have a warming midrange 

Vienna Acoustics.

Try to find the original Olympica series used or NOS. The previous series are more towards Franco Serblin sound having warmer midrange, intimacy, they are more engaging and musical. The NOVA series have the "modern " sound with tilted high frequency, I won't describe them at all as warm.
