In no particular order. Should be able to find for $300 up to $600 preowned
Sound Dynamics RTS 3
Linn Tucan (recently on audigon)
Spendor SP 3/5
Dynaudio 40, 42
Totem Arros (floor standers) suprising bass in a small room
Spica TC 50s
Mission 70, 700
Epos ELS 3
I have owned the S 3/5, ELS 3, Mission 70, RTS 3s and Totem Arros at one time or another. All great speakers. If you go with a floor stander, the Totems throw out a very large sound stage, have suprising bass, a very small footprint, easy to drive (ported), easy to place and do not need stands. FWIW
