Yes... that's a common problem that many struggle with. In my experience, the best solution is to own tube gear that allows for a variety of different tubes to be used to fine tune the sound to your liking. While tube rolling can be expensive, it's less expensive and stressful than having to swap components... and I find the experience of tube rolling more rewarding and educational.
Warm vs Revealing—the struggle for balance
For me my upgrade path has been finding balance between warmth and dynamics/detail.
It’s looks something like this: find satisfaction (Raven Nighthawk + Tekton), get upgrade bug seeking more dynamics, get more revealing gear (Ma 352), feel fatigued, buy new tubes (Telefunken) and speakers (SF Olympica); want more dynamics (Mc 601 + c50), I immediately get tube pre because of fatigue (c2300), still too sharp (new tubes and DAC); excellent balance, but of course sell speakers, new speakers too revealing, buy Cardas cables to replace Wireworld (ahh just right for now, but may be a little more revealing might be nice).
And oh yeah, working on fixing the damn room problems!

Anyone else doing this back and forth?
