There's at least 40 amp companies I'll probably never get to try in my lifetime. I've just accepted it.
I feel grateful that I had a "lot" (from the perspective of a guy who played through a tube amp for the first time in 2015) of amps to tinker out with over the course of my playing life, having started seriously only when I was 19/20. Soldano, Mesa Boogie, Marshall, Engl, VHT, PRS, Victory, Diezel.
There are so many I haven't experienced, like Orange, Bogner, Omega Ampworks, Driftwood, Revv, etc.
All said and done though, I think it's great to have been able to find "my sound" (whatever that means, given how your mood can define your perception of tone). I really think I learnt how to dial in amps as well, and of late, I think my recordings have also benefited.
There are just too many for me to reasonably purchase and hold onto with valid reasons, with just about 20 years of working life left (ugh).
All that stuff I tried, however, led me to the conclusion however that rack units maketh the man, at least in my case. So much fun to do odd pairings.
I could do with another Diezel VH4 or maybe a VHX though, hahaha. It never ends.
