Loudspeaker under 3000 new or used

May I suggest, Dunlevy III's or IV's, check out Martin Logans as well, several models will meet your finicial requirements. GOOD LUCK !

You can get a pair of used Vandersteen 3A Signatures for about $2500-2600. I own a pair of these excellent full-range speakers, and think they are a bargain at their MSRP, and even more so at their used price.

In that price range, but with different equipment driving, I had very good luck with NHT, I bought 2.9 because 3.3 had to be played a bit too loud to sound great.

Certainly you'll not do any better than Sonus Faber Electa Amators in the mid to high $2k range used!(original versions,not version 2 current). These are bookshelf monitors. Although you wouldn't know it by the sound! Top to bottom, they are simply world class! They need a strong amp to drive properly(solid state only need apply) but will play the best 35hz-20khz you'll likely ever hear in this life time!!!...Class A stereophile rated
