Just stumbled across this thread. I've got a pair of the LS-2s that I got back inthe 80's when I was living in upstate NY. I replaced a pair of Magnepans when I heard them. Still my main speakers. (Spica's in the office have similar open sound and I've always suspected the near-cylindrical enclosure is the key)
What did you end up paying, if I may ask?
Mine still sound beautiful and have great imaging, but seems a little lacking in the extreme high end. I've been lusting after a pair of VMPS RM-2 -- their ribbon tweet is really sweet, but of course they're 4x what I paid for the LS-2s back in the day. If any of you have heard the LS-2s against speakers with ribbons I'd be very interested in comments.
I have some other details in my files on the LS-2s if you're interested.
