Keep your eye out for a great condition used pair of Legacy Audio Signature SE around the $5K price. Very easy to drive, great Air Motion Tweeter, and bass down to 22Hz.
KEF R107/2 vs REVEL f52
My kef's are getting a bit long in the tooth and am looking for a drop in replacement for them, The 107's were amp friendly unlike many other kef models they only needed power to come alive not incredably expensive power. so I can get a pair of F52's for a fair price and want to hear about them.
