amp match for quad esl63

When I had ESL63USAs I loved using Dehavilland 845 monos, which crushed a Cary Rocket 88. The Berning ZH-270 was also fantastic. I heard a number of 845 and 211-based amps which in general were head and shoulders above the other tube type amps. Cheers,

My buddy used an ARC D-115 for years with his Quad esl-63s. He still uses the D-115, but the Quads are long gone...
