Amp for Quad ESL 57

I've tried a number of different amplifiers and find that vintage English tubes is what they prefer. I'm currently using a Radford STA-15 that sounds wonderful.

Leak Stereo 20 works as well but you will need to pot down the input.

The Quad II Classic (re-issue) or the original Quad II are much better amps than the Quad II Forty. I have the first and with NOS EF 86s (Amperex or Mullard) and a NOS rectifier (a Mullard GZ34 or even better a GZ32) they are very impressive.

I would look for a Berning as well. Another great choice would be an Atmashere.

An old pair of Futtermann's LOL

Glad you like the speakers. You have a particularly amazing pair of Wayne's work.

Your speakers have protection boards installed so any amplifier will work without damage to the speaker.

Quads like amps with beefy, stable power supplies. Don't be afraid to give them some power. You will be amazed at what a 50-100watt tube amp will do with these speakers.

I use a pair of ARC D70mkII with the Quad ESL. About 65watts/channel. Wonderful tone, huge well defined soundstage and fantastic 'grip' on those bass panels.
