What tube amps for the Quad ELS 63

Another helpful tip on Quad setup is not to toe them in. Leave them parallel to the wall (hopefully, several feet) behind them.

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).

I am quite knowledgable about Quad 63's and would gladly share my knowledge. I will talk with you if you call 989-673-8493 in the evening EST. Ask for Denny. Suggestions without knowing what you are trying to accomplish have lttle if any relavance to reality. Good luck.

I've had Quads all my musical life and I would say that the advice given above holds good. I have nothing to add to that or to disagree with. Linn and Quad musically do not go very well together.The Quads show up mercilessly all the inherent faults of the Linn stuff. If you want to stick with the CD player, why not try to get one of the older CJ amps, which would give it some warmth. Stay away from AR gear, its too "cold" in that combination. The Berning mentioned above, would be a possiblity, a RM amp, would do as well, and Jadis, the 80 monos of course, but they cost a packet, or the Defy 7 by Jadis, which has lots of punch. I am not familiar with other tube gear in the 100 to 150w range, so I am also curious, what the other contributors are going to say.
Cheers,

I've used two tube amps with Quad ESL 63's that have had the wonderful Nick Gowan upgrade (62' of inferior wire replaced, among a lot of other, more obvious things). One was a heavily customized Sonic Frontiers SFS-40, the other was a pair of Atma-Sphere M60 II.2's. It was no contest, in favor of the A-S amps, which are legendary for their ability to get great sound out of electrostatic speakers. As far as I can see, the legend is the simple truth.
