What tube amps for the Quad ELS 63

you didn't ask for set a set up question but your comments on your sound tells me that either they are not set up properly or the electronics are off. these are great speakers but set up can be very difficult. i spent a long time getting them right. tube electronics go well with quads but they can still be bright and less than optimum with the best electronics if your not spot on re set up. If your using stands, try putting them on the floor. with stands you really need a sub woof. there is a large upper bass suck out which will make them sound cold. give them plenty of room from the back wall and make sure the area behind them is not reflective - dispersive is much better. also, i think many people, including me, feel that the speakers are a bit dry in the upper mid range - you might want to look at amps and preamps that are noted for some warmth. Re amp recommendations, what price range are you looking in and are you considering used as well as new?

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,
