Anybody heard Martin Logan Summits?

My system consists of Quad 988's, Thor Audio(tubed) TPA-150's, Thor Line Stage, Thor Phono Stage, Thor Dac, with Cary 306/200 as a transport, Audio Physics Minos Subwoofer,
with a VPI Scoutmaster turntable and a Clear Audio Discovery cartridge. My room is 20X 20 with 12 foot ceilings and my room has been heavily treated by Echo Busters. The probelm lies within my Quad 988's. They have
some wonderful qualities, but have limited dynamics and poor bass response. Without the sub, the sound is poor. I am seeking a true full range speaker that is detailed, moves a lot of air and will make me feel that I don't want to look anymore. My budget per pair maxes out at $15,000.00. I would prefer to spend less. I recently heard some speakers at the show and was not impressed. I am in the New York area and in fact today I am going to hear the Reimer Grand Tetons in Patchogue, New York. I will advise arfter I listen. They sell for about $6000.00 per pair. This has been a difficult journey as I realize that all speakers are a compromise. I also feel that I want an efficient speaker. This leaves out, Sound Lab, Avalon Eidelon.(used comes in at my max)I have spent so much on electronics and feel that the Thor tubed gear is so good that I won't consider changing amps to a 300 per channel solid state variety. Any thoughts would be helpful.
