What tube amps for the Quad ELS 63

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.

I have owned ESL 63s since 1981, 1984, 1992, three different runs. The very best amps I have used on them were

ARC D-90B
ARC D-79
ARC D-150
ARC D-115 II
JADIS JA-80 (When they sold for $5500.00 New)
Conrad Johnson MV-75A
LEAK Stereo 50
Try any of thes amps with a good solid Sony CD Unit with motorised volume and never look back. You wont be very far from the truth.....Frank

My small experience of old with 63's (10 yrs ago) both agrees with Detlof's &, strangely, agrees & differs from Frank's above:
-The small Jadis (now Defy7) gave me great joy;
-The Jadis 80 were my "reference" at the time; note that these were wearing ancient GE tubes -- I couldn't afford to re-tube them!
-Old Symphonic Line RG4 monos (ss), were at par w/Jadis 80 in driving, but I slightly preferred the sound of J80 over the S-Line in the upper mids (maybe due to my being accustomed to tubes)
-The Quad-Linn combo's I tried were... off (surely not only a matter of components synergy but also of set-up on my part)
- EAR 519 monos: good synergy & drove the speakers well
-The A-Research I listened to (the 150, I think) didn't quite involve me emotionally.
-Finally, Quad's own 45 (?) ss, sounded harsh

Note that during that time I was using a DNM6 pre with the power amps, only had a few cd's, and listened mostly to, and judged by vinyl.
