I am using Cary 805C's with Quad ESL63 USA Monitors and have found this to be an excellent combination; provided, however, that you want to keep the volume reasonable. I drive my ESL63s full-range and at moderate volumes in a medium-sized room. A friend of mine drives his Quads in an actively bi-amplified system that cuts off the low bass fed to the Quads. This should dramatically reduce his need for power. He still has problems living within the limitations of 55 watts. So, be warned if you like to listen loud or have a cavernous room.
To me, the 805C's have fantastic warmth and beauty in the midrange. If that is what is important to you, you should feel free to go the way of the 805C's.
