Can the need for novelty and change be mitigated by rotation?


There is a not too serious term audiophilia nervosa; it may be a joke, but it builds on a valid observation: there are people who are never content with their equipment in medium term.It is not the initial period, when one does know much about gear and learns; or the question of disposable income, when one gets the best they can afford, and upgrades untill he (or, probably less often, she) buys the dream system. Audiophilia nervosa is a state later on, a plateau, when a desired piece initially gives much satisfaction, yet it wears off, and the person gets uneasy and looks for smth. else.
To give a personal example, I was on a quest for my ultimate power amp. Had to be Pass Aleph; happened to find Aleph 4. Did not suit the speakers (Lowther Fidelio) too well; got other speakers (MBL 101b or c) ; still not there; got ML no. 23. Much better; but still uneasy about Aleph and speakers for it; got Gradient 1.5; fine with ML, Ok with Pass; exploring options, got Parasound 2200 mk2 (and a couple of PA amps). And I needed a preamp. Seller insisted on only trading ML no. 28 together with no. 27, — another power amp.
Now the ML 28 is there to stay; Gradient 1.5 are keepers too; but I’d keep old MBL101 even if they stopped working (I’d probably use them as garden sculptures), so they stay, too. But I have way too many power amps (the listed, and a few more), I would need to sell some.
The trouble is, I cannot decide. So, in order to decide, I rotate them. ML 23 is very good with MBLs, fine with the Gradients. ML 27 is very good with the Gradients. Parasound 2200 2 is very good with the Graients, - but in a different way. So I swap every few weeks, and I still cannot decide.
And after each break I [re-]discover things I like about the particular amp / amp-speaker combination.
Again and again...
Which made me think:
— What if this ‘rotation’ takes good care of my need for change and novelty?
After a while I will decide which one(s) to sell, and later on I will probably want smth. new. But for the time being, keeping and rotating them slows down my pace - and I see it as a good thing, as in the aftermath I do not think my decisions have been sufficiently well informed (for instance, I am getting used to the fact that I actually do not like sound of Pass Alephs as much as I thought I do, and my Aleph 4 may be the first to go).

Congratulations! You have discovered an aspect of audiophilia that is quite appealing to a subset of enthusiasts! These are the listeners who as a pursuit, a goal, seek variety.

Some of this is in my character, and I see it expressed in my life also in terms of motorcycles. I would rather have two fine motorcycles of quite different genre (cruiser/sport) than one considered higher pedigree. The excitement of the distinct difference in experience is better imo than being held to only one experience. I have no doubt that in the moment, riding a higher level bike would provide some unique experiences, however it cannot provide the variety of experiences. That is the crux of the dilemma; if you put your money to work in a restricted fashion, then you will not get the variety of experiences, or at least not when you wish.

I spent a long time searching for "The One", the one speaker, the one system that would ultimately satisfy. Because I always heard deficiencies in the sound regardless of what equipment was used, I finally realized the performance spectrum is SO wide, and the inability for any rig to capture a nearly perfect sound internet, that I started to expand my components and speakers. Over the years, the focus has turned solidly to speakers, because their physical characteristics are so varied that one simply cannot get similar sound from a different genre of speaker. I also learned that this does not change as one moves up in the quality of the electronics.

This has brought FAR more contentment, enjoyment, exposure to the experiences of the High End than any pursuit of The One. Variety is not a problem, but a great passion and pursuit. It is a legitimate means of enjoying the music, of course not for all, but every bit as valid as any other expression of involvement in the hobby, i.e. being a Mediaphile and focusing on collecting and curating media.

What level of equipment does one need to attain in order to not be plagued by perceived imperfections in the sound quality? That is for you to figure out; it’s personal. But, I attest that when one reaches a high enough level of sound quality with the capability of swapping around systems, it is a pleasure that nothing else in this hobby for decades provided.

Concluding, then, your post as stated in the title suggests that variety is a sign of some issue, problem. Not at all! It's only a problem if you are unaware of the vast spectrum of performance, cannot accept deficiencies in systems, and do not want to spend any money! If you address the realities of the process of setting up rigs and accept that it is a great alternative to anchoring to one expression of sound, pursuit of variety is fantastically fulfilling! 
Swapping out components does make for an interesting time. Some items remain in the system for months. Other items are shelved in short manner. Some units thought as inferior, once replaced, are quickly returned to their original position. 
The OP is right.... I just picked up a preamp , I really liked how my system's personality changed by swapping it out.   I think I'm going to keep it in place for a while..  I finally have enough nice gear for two systems plus , but at the moment don't have space for two separate systems so ill pair this with thar, enjoy that combo and swap things around.
