I can’t say I like tweaking things, I would be more happy to plunk things down and enjoy. But I long ago learned that will not get great sound. I will say I now, once I get to a new higher plateau of performance and am very happy to stay there for many years, so I can just enjoy the music.
I learned long ago if you reached the balance of tone and detail that you want, if you then change a component, it is going to resulting in some imbalance (tone or detail vs musicality, etc)… and if not that, some components will then be holding back performance of others (my rule, only 2x or higher investment in a component). Then you get thrown into a new upgrade cycle. But I think it took me twenty years to get to my first really satisfying plateau.
