What amp do you use with your QUAD'S?


I have had a pair of original QUAD ESL's in my system for about 15 years. The amp is a Berning 230 which I love and will always keep. I'm curious about what other owners of this speaker use to drive them as I would like to get a but more volume out of them from time to time. My musical taste runs from rock to classical with a smattering of jazz. I listen to classical mostly. I have searched the archives but really haven't found much. Hope to hear.

As a starting point you may wish to check these two websites out:

FWIW, I drive my Quad ESL-989s which I believe are each the equivalent of two ESL-63s quite happily with a Conrad-Johnson Premier 140 amp.

Good luck in your search.

I started with an Audio Research CA-50 with Quad ESL-63's. Upgraded to Cary SLM-100's and finally to a Cary 805c's. All worked very well. Only the Audio Research seemed like it needed a few more watts to properly drive the Quads.
Would still like more on what everyone uses on the ESL 57's. Thanks for all of the input provided! Keep it coming!
