+1000 Doug Schroeder's and other's comments. Variety is the spice of life.
Ah, but there's the rub. Is it variety or is it nervosa?
Variety is when one understands and intends that what is happening is the "rotation" (as the OP put it) of gear for the sake of variety. Variety is consciously accepted as a value and goal.
Otherwise, it's not variety; each change is a stepping stone toward the "absolute" sound. (Makes me wonder if monotheism is ultimately to blame for audiophilia nervosa. Just one God? Really? Why? And....we're off to the theological debates! "Just one wife"...uh oh.)
Let's say that change is not seen as good. So that makes it a psychological condition; perhaps this might help:

As for Mahgister's comment about room acoustics ("embeddings!"), he/she/they don't really solve the issue. Because room acoustics can be constantly changed, right?
So, as much as he thinks he "solves" the question -- once again telling gear swappers that they need to focus on the room, baby, the room! -- one could swap and change embeddings and acoustical treatments with as much "nervosa" as others swap gear. There is no way to "rightfully embed" a system if one does not have a single acoustic "sound" they're looking for. He says "One system rightfully done is enough." The issue is "rightfully." So, no solution from the balcony.
(And Mahgister, look: I'm sympathetic with your critiques of consumerism but let's be honest -- no matter how many times you mention that your system cost $500 and everyone else is wasting their time and money if they don't tackle "embeddings" that does NOT address the issue that the OP stated. Because, it's quite possibly NOT about money or stuff or consumerism. It's about optimizing *experience.* Does the room matter? Of course. Could someone go crazy constantly adjusting and changing their room, even while spending no money, just because they cannot decide on what kind of sound they're looking for? Of course. Would that nullify arguments made on the basis of consumerism? Yes, it would. )
We're at a philosophical fork in the road. Is the good One or Many? Well, it depends:
