Without question - the Quad ESL 57’s are the best for the acoustic music that you like.
The ATC’s would be also - but they’re expensive.
Next choice would be Harbeth 30.1’s / 30.2’s / etc.... which sound very much like the Quad ESL 57’s. If you want something for near field - the Harbeth P3SR sounds very much like the 30.1's / 30.2's...
But... if you can accept the look of the restored ESL 57’s and have the room and matching electronics - nothing really comes that close, except possibly the 30.1’s / 30.2’s...
In fact... I’m seriously considering the ESL 57’s myself.
