Original Quads (57) - the perfect amp

OP, with such programme material, you might enjoy addition of air, separation, and greater front to back spatial rendering, trying Max Townshend's Supertweeters. Designed specifically for ESL57's. Listening to the kind of music you note, even, at low volume in the evening resulted for me in a magical bath of sound. (Electrostatic Solutions rebuild at 89dB efficiency and 4W + 4W ADI valved SET, (15' x 13' x 10' ceiling room)). The SET was part of the magic. Alas by comparison my rebuilt Quad 303 was dry with markedly reduced colour. If you go the SET route, check with amp and valve / tube manufacturer on long term operating conditions. Alas, I had no space for my 57's, and so they went to a very happy fellow listener.

Original Futterman H3.  Quicksilver Minimite Monoblocks,  Antique Sound Lab AV 25 Monoblocks. 

The Bedini 25/25 is known for its synergy with the ESL 57. What may not be as well known is that the Futterman H3 OTL was also highly recommended for use with the Quad 57. I’ve never owned a pair of 57’s, but I did own an H3 and early 25/25 which I used to drive 15 ohm Rogers LS3/5A’s. These we’re both successful pairings.

Owning both the ASL AV25 and QuickSilver MM mono's, I would think that they would also have a great synergy with the ESL 57.

Thanks everyone for confirming the Bedini, seems like a sure bet.

@terry9 , thanks for the DIY suggestion, got the skills but

corporate America and my three young kids aren’t agreeable ;-), but a great option down the road …

@psf4972 , really interesting option those superweeters, and appealing for the low volume capabilities  

Here ESL57 + Luxman C900U  /  M900U

I guess it is overkill but I like the result 😀

Weren't the old Leak and Radford amplifiers supposed to be good matches?
