I heard a lesser version of these superb ESL speakers being driven by Jeff Rowland monos at the Heathrow show years ago and I never forgot the articulate, natural but also dynamic sound they produced. The best I heard at the show. I recently found a pair for sale and just had to try them, being the first ESLs I've ever owned. Quad ESL never did it for me for the music I listen to but I can say these Wings have a beautiful mid and top, hearing breaths and nuances in the music that I didn't hear before. Their bottom end is amazingly punchy coping well with some faster music. If a lot of your music is vocal, girl+guitar, folk then these just need to be heard! Although this constitutes some of my music, the majority is more complexed synth/electronic/bass/vocal/guitar so box speakers can reproduce this more to my liking. If I liked simpler more relaxing music, I'd be keeping these.
They're single wire with WBT posts and come with the Fins (an extra $1500) which fix on the back allowing better sound dispersion and dynamics. They're in great condition in original boxes and manual, weighing approx 30kg. The fins are in a separate box (one set without a box). The Wings I believe are Audiostatic's top of the range speakers.
Selling for £1100 (cost approx £5000 new) and can deliver around M4/M5 areas of Bristol area. For collection you'll need an estate car as they're 2m long. An insured courier will be risky and expensive so collection/meet up is my preference.
