Ugrade-itis - is there a cure?

And as hobbyists, I think there’s always an interest in tinkering, improving, etc.
What helped me was shifting my focus to the records (or whatever your preferred medium is). Lots to learn, lots of music to get played that’s new and different to you and a huge amount of history to the recordings, the artists, etc. You can get all geeky on pressings if you like to improve sonics more.
But, it isn’t just something to keep me busy.
It’s the food for the machinery. And into the maw it goes. Some stuff gets put on a shelf and forgotten (yeah, I do purges every once in a great while) and some stuff becomes part of me.
After all, that’s what we’re chasing this good sound for, right?
It will definitely keep you off the street, and probably help appease those "I need something new/different" blues. Ain't no cure. 

I agree with @geoffkait that one addiction is often dealt with by replacing it with another (the shrinks can weigh in on that one).
The solution I proposed-- chasing records (whatever your medium) at least gives you more to feed the machine and is aimed at what I think is the whole purpose of this hobby- to reproduce music for enjoyment. At least that's how I got off the hamster wheel. (I still change cartridges, replace worn tubes, etc. but I'm not seeking equipment).
Maybe I'm an oddity in this- I will put together a system and once it is 'good' in my estimation, I'm not really in the market. Over the years, I have assembled a number of systems, but it's not like I'm constantly on the search for the latest and greatest. I've kept most of my stuff in these systems a long time.
