I'm 99.9% happy with my current rig. Although I've tweaked it recently to see if changing the tone a bit would sound better on stage, I came to the realization that my previous setting was much better.
I'd like to eventually get an H&K TriAmp MkII, but in all honesty, if I were to replace my current TriAxis/2:90 setup, it'd make setup/teardown at gigs much more work and take much longer than it currently does. I like everything the way it is. So I'd say yeah, I'm not really gassing for anything new anymore.
Maybe guitars, but ampwise, no.
