In praise of the ESL-57


About a week ago, I was doing a Kijiji search for some kind of EL84 amp that would be suitable for a rebuild. Buried in an ad for an amp was pair of ESL-57's also for sale. Based on serial numbers and production dates, they were from the early 70's.

Out of curiosity, I asked if the Quads were still available. They were and he had re-listed them in a separate ad at a reduced price. They were missing legs/feet and according to the seller were great otherwise. Grills looked to be in decent shape and after a bit of back and forth, I decided to get them.

Was pleasantly surprised when we arrived to get them. They looked quite good. No problems that couldn't be addressed without a little TLC and elbow grease.

Took a minute after I brought them home to plug them in, and when I eventually did, one was dead. Bad power cord...

Let them sit and charge for a bit and then started running them. After a little repositioning, they were set up as they should.

All I can say is wow. This was my first experience with these lovely speakers. Because of Covid, couldn't audition them before picking up and I have not had the opportunity to listen to a pair before. 

I now understand why they have the following and reputation that they do.

Everything I have read about these speakers is true. The first track I ran through them when they were set up was Jazz at the Pawn Shop. At some point during the intro, there was someone in the audience that "yelped" something or another. I was startled as I thought there was someone standing behind me. Crazy!

I'm surprised and how good the bass is on these. Based on what I had read, was not expecting them to have the depth that they do. (This is from someone who normally listens to Cornwalls...)

The "head in a vice" thing is very true for full benefit, but as I am currently listening to the radio in the background, they are filling the room well and are not fatiguing in any way, which is odd when you consider how fast/detailed/articulate they are.

So very pleased with them!!! As soon as time allows, some temporary legs will be made so I can both get them off the milk crates as well as figure out a design for what will be the final legs.

I had a poor mans HQD w stacked pair, Decca ribbons and a pair of Watkins / infinity 10” in a transmission line, fun :-))) the bass on the panels is decent as others have said. I have a 303 laying around that I can list ...And a pair of 63 parts bin early serial numbers...
I ran mine ( Panels ) w 2x CJ MV45A..... Sweet sounds.... many moons ago
I’ll second the comment about using a Bedini 25/25 with those speakers. I have no idea why they work so well together, but they do. 
My first pair of 57's (1981 - 2000) were used with the Bedini 25/25 and a Futtermsn OTL. Both amps sounded superb with the Quads! 
The Bedini eventually needed repair,  the Quads and Futterman were sold. Now twenty years later I am starting over! Bought two pairs of 57's and a pair of Futterman H3aa's. Plan to stack them! 
I had a pair back in the 80s. Sold them and moved to cones. Never forgot that transparent sound and bought a very clean pair a number of years ago. Love them. I took the grilles off. I'm using a pair of modified EICO HF35s at 16ohms. I have them on 20" stands mounted at 90° upright and toed in. See my Virtual System for pics.
