Amp for Quad ESL 57


I recently bought a pair of Quad ESL 57, Wayne Piquet modified. They are simply amazing. I am currently using my McIntosh MA2275, and it does a good job overall. However, I wonder whether the new Quad II-Forty might a better choice. Any idea?

I was a Quad dealer for years and sold a pair of 57s to a friend who has had them 32 years. I just visited him and he is using a rebuilt Heathkit amp by Foster Blair which sounded as good as anything I have heard. Classic tube gear rebuilt by Foster in available on the Mapleshade site. I have two of the Magic preamps he use to build and they are exceptional.
i have settled on a dyn stereo 70 and a consonance m400 monoblocs (40 watts, el 34, push pull and triode mode).
hi ralph:

since i like a "dark", euphonically colored presentation, i would prefer the stock version, unless you are aware of a mod which would further darken the sound.

most mods tend to clarify and increase focus. this is not the direction i want to go.
My vote would go to the new 50A amplifiers from deHavilland. These are re-makes of the original 50A's made by Fischer in 1954. We used them at the RMAF with WB speakers. Kara has used them with Quads. I promise you won't be disappointed. You can check them out on her website at dehavillandhifi.com
