Well, I used to swap more often than I do currently. Maybe once a month or so.
And previous to that I used to do it almost every night. That's because I used to use my home theater (Hales) speakers for two channel as well. So I had speaker wire leads from my tube amps sitting near my HT L/R speakers, and when I wanted to use them for two channel I'd just unplug the speakers from my home theater cables, and plug in the cables to my 2 channel tube amps/sources. So banana plugs were very easy to deal with.
Still...I own at the moment 5 pairs of speakers that I swap in and out, so any connection that makes that easier is the one I prefer.
