Talon Raven or Khorus, very good.
Energy Veritas 1.8 or 2.8, very, very good.
Talon are efficient, Veritas are not.
Aerial 10T's are quite good, not efficient.
Meridian DSP-5500's, good - and have amplifiers built in.
Most, if not all of these can be had for less than $2,000!
Obviously room, gear, ears, music/usage play a factor - but I don't have a problem making these suggestions. My list above is actually the order in which I would pick from the list - and 98% of folks listening to these would be extremely happy with them.
IMO - Dan
