I just recently sold a pair of 1.6QR's because we moved and the new listening room was only 13 X 16. (The old room was 15 X 25.) Actually the speakers sounded OK in the smaller room but the big problem was placement. Magnepans must be placed away from the rear and side walls. The room served other purposes so it simply didn't work to have them sitting where they needed to be placed to sound their best. If the room would have been solely dedicated to audio I'd probably have kept them.
