Amp for Quad ESL 57

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.

Should work well. I use to use a Dynaco Stereo 35 in the 60s on them and the Mac should do at least as well, power makes little difference as they don't use much but big amps can also sound very good if used carefully. The 8B in triode mode was suppose to work very well but I never had them at the same time.
