speakers that are a little laid back in the mids

Wharfedale EVO4.2

Wharfedale LINTON 

My Vienna Acoustics Beethovens circa 2000-2004 have that slightly recessed mid from around 6-800hz to around 3khz is a smiley face. I'd owned the Kef R105/3 for around 12 years before buying them (ruler flat response) so when I'd swap the VA's in and turn the volume up so vocals sounded the same the VA's sounded so much more impressive and detailed in the highs and lows specifically because of the recessed mids. I've bought and sold at least a half dozen more expensive speakers since but the VA beethovens stay in my living room.

The key is finding a combination of speakers and amplifier which glorify the midrange not hype it. 

Sophia Electric has some organic sounding amplifiers EL 34 and 300B and more. The devores might be highly resolving and organic. Not a big fan of horn loaded tweeters, they tend not to have the midrange fullness that I appreciate. 

I tried the Lintons, they were pretty bad

I've owned Otello's for over five years and your description of their midrange doesn't match what I hear.  I would suggest however that you get them farther off the wall behind them.  In my current room which is 17'x 26' the fronts are almost 6' off of the wall behind them but in the last room which was only 14' x 17' the fronts were 4' off the wall.  If you haven't, look at the placement calculator online in the newest Othello manual and try those calculations as a starting point.
