Solid State Amps for Quad ESL 57?

Adam, your stacked Quad frames look amazing.

I used a Bedini 25/25 on Quads (my fourth pair of 57s)  it didn't bring anything special to my listening enjoyment. For SS I like the Spectral DMA-80, a little bit more money than Bedini but did it all for me. Ping Robyn Wyatt at Robyatt he and David Chesky have tried MANY amps on 57s. AFAIK, David settled on the ASR Emitter I for his reference system.

Geoff is SO right about the stock perforated metal screens on the 57---horrid things. Jerry Crosby (known for his QUAD 63 mod) at one time made a replacement for it, with much larger holes and much less resonance.

Thanks noromance......just a bit different way! :)

If no kids or pets, I really don't see a reason to have any kind of screen!
Before the rebuild, in original state, I tried the difference with and without screens and immediately I knew that the screens are out!

Another controversy is on this link:

In the end of the review it says that the FirstWatt F-7 sounded better than the ASR Emitter II amplifier!!

Like saburo said, ASR Emitter II amplifier is the amp of choice for 57’s and the best match of Chesky, Wyatt!
And when I wanted to replace my tube amps with two FirstWatt F7 amps (one amp for each side) and speaking with Marc from Reno HiFi, he said that the F7 can’t drive a pair of 57’s.
He recommend PASS XA-30.5, or 30,8 at list!
