Speakers known for great midrange.

Sorry.  If great midrange is your priority, you need panels/electrostatics.

Could put them on stands I suppose.

Budget is 5000.00. 
 

QC issues example: 

I had a pair of older Spendor 2/3s that were wonderful for the midrange with tubes. Contrary to what folks say I thought they rocked well with rock music as well. Not to mention the great deal I got on them with stands included. I think buying used with speakers is the way to go, provided you trust the seller’s packing ability. Bought the Spendors and my EgglestonWorks floorstanders from A’gon. 

That’s shocking !

+1 for Dynaudio. Have owned their products for 30 years, and most recently bought a pair of pre-owned C1 Platinum's for $3500 from TMR. All the usual audiophile superlatives apply plus midrange in spades, and bass that defies the laws of physics for a cabinet their size.
