Best speakers for $3000

Check out the Spendor A5R. I’ve owned a few Spendor floorstanders and I think they would fit the bill!

Magnepan 1.7i and DWM hands down for jazz!!!!

Consider a home audition of Ohm Walsh 2000 ($2800/pr).  You have enough juice for them, and they do just about everything well.  As long as your room is not larger than the recommended room size for the speakers (see the Ohm web site), you might find them the perfect solution to your search. 

Magnepan 1.7i good, Eminent Technology LFT-8b "gooder"!

For  your  about $2600 you can build the Linkwitz LX521, and then for about $400, score a used B&K AV1260 to drive 'em.  There isn't a loudspeaker made, at any price, that exceeds what the LX521 can do.
