Current line-up from Quad (British, good rep. and in Cambridgeshire) is the 2912 full sized ESL and its smaller sibling, the 2812. Ive heard the 2812 and it's as goos an ESL as you'd want or expect. I have the predecessor of the 2912, which is the 2905 (and again, with a smaller 2805), both of which are almost identical to the newer ones. Before that, the 989 and 988; still v. good.
The numbering is a bit confusing so may be slightly out there. To my mind, the bargain now is the 2905 in silver and black, which you can get for around the £2K mark; there are plenty around. The big and smaller versions of each incarnation have, I believe, the same footprint, so there's no (sensible hifi logical) reason to opt for the smaller one, which loses some dB in the bass.
Amazing transparency, soundstage and imaging, but needs a bit a space, esp. (about 3 feet+) behind.
