I just heard the Summits yesterday and they are by far the best speaker ML has produced to date. Bass is tight and fast and the clarity is amoung the best I have heard. They where using Musical Fidelity to drive them, which was a very good match for these speakers. I have heard the ET and they are damn good, but these are much better, but the cost could be a major factor if ML and or dealer doesn't discount these. They are however coming out with a smaller version of this by Fall, which would be in the 5-6k range.
