Hi,
My EAR 519 100 watt monoblocks barely drove ESL 63s. They did sound amazing once an 18" velodyne was added. A warm amp helps as well as lots of room around the quads. A good sub x-over with a nice powered sub will not only do amazing things but will also let you get away with normal amounts of power (50-100 watts vs 250-1000).
