I sure miss my Quad ‘57s!

I owned Quad ‘57s and joyfully listened to them for 10 years! Still questioning my decision to pass them on to another music lover. But I do sadly remember the multiple times I blew up amps because of them and the sickening feelings of the many times I arched them before I had them rebuilt.
I did eventually opt for more bass and treble but have missed their incredible mids now for decades.
Guess there are some new rebuilders who have been able to get more bass and treble? But I now have evolved the feeling that good enough is good enough. And man, were they good enough!

@mglik, if you decide to try the ESL again, give Kent at Electrostatic Solutions in Kansas City a call. For an amp, the Music Reference RM-10 was designed using the ESL as it's load, and is perfect for it.

Roger's (rip) RM-200 was the best, as it has 1 or 2ohm output taped transformers, with the 2ohm tap it drove the ESL63’s to perfection, but it’s 100w gets knocked way down from the 8ohm tap figure, but still enough to get decent level out of the ESL 57’s

True George, and the lower the tap, the lower the output impedance, a very good thing with the ESL (it's impedance swing is brutal, insane). Interestingly, in my last email with Roger, he recommended I use the 8 ohm tap on the RM-10 with the ESL, not the 4 ohm. I asked about his "light loading", and he said yeah, but the ESL is mostly a 16 ohm load, so the 8 ohm tap IS light loading with that speaker. When I get my Quads up here I'll try both amps (RM-10 Mk.2, RM-200 Mk.2), and all taps.

My Emotive Audio Vitas drove my Quad 57’s for 15 years without any issues. But I have also moved on the other speakers and right now find my Bache Tribeca speakers to be more satisfying. Maybe I should connect my Quads again during this lockdown.
