There used to be a record store that I'd go to occasionally that had them. I wish that store was still around, as I've moved to what would be about a block from them. They always sounded nice in the store, as did a pair of the awesome looking Design Acoustics D12 hexagon-ball speakers I heard in a record store in Portland once.
Hmm... I'm looking for a pair of vintage speakers for my office (the sunroom in the this thread, no more audiophile pretensions for this room. Maybe a pair of those PS10s... though I was thinking of Dynaco A25s as I miss the pair I used to have.
