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).

I have about 12 sets of headphones.  They all sound different, and there are different things about them that I enjoy.  It's nice to have options. 

Of course in my main system, most of the components are a lot bigger and a lot heavier than a set of heaphones, so I'm less inclined to move things around for that reason alone. 

I have more than one system, so I can move things around from one system to anotherif I want, and I have a couple of "spare" pieces, but I'd rather sell them and let someone else enjoy them than have them sitting around so that I can switch things up if the urge hits me.  Reminds me, I need to take some photos and post some ads this weekend...
Part of my premise is a question if past some threshold we can meaningfully speak about “better”.
There is a broad agreement on what sounds poor (for instance, we had Grundig “Party Center 2200” when I was a teenager; fine for radio news, orherwise crap). I recall Williamson did a lot to set benchmarks. Past that lies the land of diminishing returns, where different people prefer different things, and “better” becomes individual.
If swapping into the system a different piece of equipment which was set aside for a half a year causes me similar [positive] emotional reaction as a new piece of equipment, I interpret it that I have reached a plateau. Most probably it is my hearing limitations kicking in, there surely are much better ears (I cannot sing, at least I dare not, and, more importantly, nobody asks me to)... but I am not so sure whether there is a strong correlation between good ears and audiophile hobby (that could be an interesting research topic).
It is a scientific fact that people in average think that they are better than the average person. So audiophiles normally should believe that they (we?) have better ears than the average person. Before research, I have my reservations to agree to that (for one thing, I believe research consistently shows that women have better hearing than men).
Moreover, if smb. hears a difference, and smb. else does not, it may just as well mean that the first person’s mind plays a trick - we often experience what we expect to experience.
So those are my problems with subjective approach to sound quality - if I observe my own behavior, I conclude that I may be going in circles. I could knock myself out doing ABX comparisons, etc., but that is already done, results can be repeated, no need to re-invent a diamond frame bicycle.
That being said, some subjective observations remain consistent, e.g., I consistently set aside Pass Aleph 4, and I prefer to it ML no. 27, 23 and even Parasound hca 2200 2. I like Aleph’s purist schematic and SE class A, but I prefer a different sound most of the time. I would not call my preference “better” though.
@inefficient,

I have an abundance of gear and yes, I enjoy swapping components when the mood strikes. I have a Coda #16 SS amp, an Aric Audio Transcend Push Pull and arguably the best sounding, a Linear Tube Audio ZOTL40 which at about 20 lbs makes it very easy to move. I find this does help the craving.

I also can highly recommend a room with cathedral ceiling such as my living room offers. There is a positive effect on the sound stage that’s hard to explain.
@lancelock 
It’s an interesting amp, indeed surprisingly light (my “hificollective” Glasshouse 300B is some 25 kg/ 55 lbs; sturdy steel chassis, but the real weight is transformers).
Thank you for the tip on cathedral ceiling. It must alter ceiling reflections and room modes - good to know that brings improvement. I guess I really need to turn to planning from acoustic perspective ... end result will be a compromise, of course.
