Speaker polyamory -- or, stories about getting a second set to alternate with your primary

So many threads out there are about chasing the ultimate speaker -- or getting rid of speakers to try something new.

Here, I am looking for different stories. 

If this applies to you, tell me about a time you had a certain kind of speaker and decided to get a second set to swap in. Maybe you had stand mounts and you wanted to swap in towers....maybe you had box speakers and wanted electrostats...maybe it was because you were super curious about a different brand...

Curious about your second, swap in speaker set...and why.

And, if you eventually fell out of love with the first pair and divorced them...feel free to confess to that, too.

Stay cool!
