The longest you have owned any gear?

Limiting this to items that are "team 1 starters":
Rogue Hera preamplifier (now at Hera II status) - almost 9 years now, which seems like an eternity here; I’ve only been seriously at the 2ch game for about 12 years. Next closest would be a Koetsu Onyx at 6 years, which I’ve had recently rebuilt (though technically this now sits behind my new Coralstone).

I’ve tried to upgrade away from the Hera twice now -- both times to more expensive and highly review/regarded tube units from more prestigious hifi companies ($10K and $14K list prices) -- and both times I ended up going back to the Hera as my preference (though it’s not without flaws). The Hera was my first true "high-end" 2ch component, and perhaps part of my preference is that its sound truly has become my reference over the years. Maybe I’ll try to upgrade from it again in a couple years, but it’s been a real warrior for me!

I'm definitely not going to win the "oldest in-use component" prize here lol. In my current main system: Tannoy Canterbury GR speakers, 5 years. Out of all the gear I still have that I might actually sincerely use again: my SOTA Star turntable (now upgraded to Nova V), 14 years. BUT I've at least been rocking Tannoys as my main speakers for 15 years; my love for them has been consistent and unwavering since my early speaker setup days :) And Koetsu isn't too far off that metric either; one of them has been my main source/cartridge for 11 year now.
