It seems that Dynaudio's excellent stand-mount speakers would be excellent contenders. Their new Excite X14 got a particularly enthusiastic review in this month's Stereophile, showing very low cabinet resonance, excellent dispersion and driver blending characteristics, and a very listenable presentation. $1500/pair; add good stand's and you're at budget.
Given your wariness of edgy treble, I also recommend you consider something using the Heil-type folded ribbon tweeter as available from GoldenEar (Aeon 2 or 3), Martin-Logan's Motion series (Motion 35XT), or perhaps even a powered monitor with this tweeter as available from Adam (available from Guitar Center of Musicians Friend) or Emotiva Pro (online from Emotivapro.com).
