I'm in no hurry, nkonor. (That's the nice thing about owning them to test out, vs a limited home audition with one of them).
Keeping both is an option, but one I'm trying to resist. I tend to like one aspect of a speaker over another and not want to part with it for that reason, hence I build up a collection of speakers that have to be culled at some point.
At this point the only other speaker in the running (for which I had a home audition) is the Joseph Audio Perspectives. Given I'm looking for "smaller size profile with great aesthetics and great sound" the Perspectives fit that bill. But they are incredibly expensive relative to these second hand 2.7s.
But I do want to try to end up with a pair of the Perspectives at some point, money-willing. Neither the Perspectives nor the 2.7 give the scale of sound I get from the 3.7s so I may end up with a 2 speaker solution (e.g. maybe the 3.7s and the Perspectives, or the 2.7s and the Perspectives...I dunno...)
It would all be a lot easier if these Thiel designs weren't gone and hence scarce on the used market now. That puts a lot more pressure on my decision, as you know.
BTW, best wishes for whatever health issue you are dealing with!
