Lest folks get the wrong impression, I do love the idea of having a variety of loudspeakers to listen to, and I do set up other speaker sets in my main listening room at times for fun. I still enjoy the ML SL3s, NHT 2.5is, and Elac Debut F5.2s.
Give me $20k and I'd load the room, Magneplanars for sure, probably Golden Ear, and other stand-mounts or floor-standers. I totally get the 'variety'.
For me, none of my five old, very old (29yrs avg), motorcycles stands out; all are fun though.
In speakers, nothing I own holds a candle to my current mains and I don't have near enough money to try another sound and get close to what they do in ALL areas of musical presentation. But for fun, I'd love more, just to goof off.
