i am surely one of the gear swappers/hoarders, been doing it off and on, since my college days in the early 80’s
to me, there are different ways to enjoy this pursuit
first and foremost, i believe there is much much wisdom in not swapping gear much, especially if you really enjoy music (and not the gear), have limited budget, and have a system that already pleases you in how it presents music you like to listen to
second, having said the first, i do also enjoy the equipment, as wonderful tools to present music beautifully... to me, these are lovely products of human passion and ingenuity -- to make gear that in turn makes beautiful music in our private spaces, music we want to listen to, when we want to... so over the years, i have found that i enjoy learning about and finding great equipment, experiencing first hand what it does, how it does it, this is cool and fun, to then enjoy the awesomely wonderful music that results ... to me it is a high order melding of left/right brain, science/engineering, for the pursuit of art/beauty/emotional connection
my second career for the last 20 years has been designing, developing, building new/renewed homes, and it is similar pursuit in some ways - a melding of business and operations with design, functionality, ergonomics and style, hard and soft skills coming together, employing construction methods to create homes that are comforting, beautiful and that bring joy to those who live in them
so for me, it is not at all about dissatisfaction or restlessness in wanting to experience (and thus changing) hifi gear, it is about experiencing firsthand what the best of this industry has to offer, in pursuit of lovely, wonderful music...(and frankly, to a much more minor degree, to call b-s on some of the hype/marketing that is thrown out there)
last thing i will mention is that since early 2020, i dove headfirst back into hifi and related gear as a hobby, due to covid, after several pretty inactive years, and i would have to say, getting back into this hobby so much, learning about streaming, getting up to date on the latest great gear, has in hindsight been vital in maintaining my humanity and sanity over this period
anyhow, my 2 cents
