I have always been partial to the Quad ESL 57. First demonstrated in 1955 and introduced to market 1957. It was a total revelation. A good working pair will still cost you a small fortune on eBay or Audiogon.
Doesn't look like a design over half a century old, does it?
I'm also keen on the speakers in my signature, but that's designer bias. No exotic woods, just red oak.
