 I just posted an important (at least I think so) message for Quad owners. Please see this link. It talks about mating a 3.5 watt 2A3 amp with Quad ESL 63 speakers.

 Within the output volume limits a flea watt DHT SET and the ESL 57 or 63 are well known performance benchmarks. There are parallel SET 2A3 amps with more power to get you more realistic playback levels. Also, if you are willing to forgo the 2A3 magic midrange you can use other larger tube DHT SETs at not that much more money. Chinese made 845 211 and the 805 tube based amps have a far more realistic output potential without much loss of midrange detail vs. the 2A3 .. You just need to get the feedback circuits defeated by your technician/modster.

I've used a SET for years with Quad ESLs - my favourite beast is the Wyetech Topaz. Over 100lbs of goodness.

Very nice

 I thought you needed 1k watt amps to make Maggies sound good?

 I don't have a SET amp, but often configure my Rogue Stereo 90 with less powerful tubes like 6L6 or Kt66 as opposed to KT88 or KT120 and run them in triode. KT66 run in triode produces about 30 or 35 watts in the Rogue and I have found this is plenty of power to run my Acoustat Spectra 22 speakers to very loud levels.
Don't know about 2A3 (would probably work fine) but I am going to try a 845 SET or an OTL one of these days. Think OTL might be the way to go given that electrostats already have transformers.
Have you ever tried an OTL on your Quads Banpuku?
