@mglik is right. I have used both Quad 57’s and the latest versions. The latest gives you an extra octave top and bottom, but there’s not all that much music there. The 57’s are just as satisfying as the latest versions.
The second best room I’ve ever heard used three pairs of 57’s, stacked. The best is my current room with 4 modern Quad ESL’s.
