I recently purchased a new pair after a 3 week audition. Am running through a Berning zh270 amp with a Modwright Oppo 95 truthmod and a custom tube switch mode power supply bass booster designed by David Berning to augment the missing octave 5db at 35 hz and below, no sub required or desired! These speakers, with the right gear are better than they have any right to be for the price. The images can be life like in size and the pitch and timbre of voice and instruments is about as natural and musical as you'll hear out of a box speaker at any price in my experience. They resolve the space and harmonics in recordings to such a degree that the music comes alive, simply an amazing value and a must audition for anyone looking for a good monitor.
