@tvad Jim Smith’s book is a good recommendation.
Magnepans were the only speakers I bought on the spot when I heard them, which in hindsight was a big mistake. I never had the room needed to set them up right like I heard them when I bought them.
The shop was Audition in Birmingham AL in the late 80s. The owner of that shop which had the reference setup for Magnepans was, drum roll…… Jim Smith himself! The Maggie’s were set up about two thirds of the way into the room well away from side walls and closer to center. Who can do that at home?
Also they are very power hungry so not just any amp will do.
