Yeah same here with my GR purchase (well besides the misfire with the 1500c). For me it was mostly motivated by wanting to buy something new and nice that will last when I’m still young and free of major bills and by getting sick of the frustrations of vintage decks.
But there’s totally a point where you can get to good enough and you’re dropping hundreds squeeze another drop from the lemon. As much as I hear a better sense of timing and bass with my new deck, my old one wasn’t bad. In fact I just did a few needledrops of the two setups, a bit closer than I’d like to admit! I suppose I’m in the unique position of taking my entire rig and moving rooms so I’m getting a pretty clear perspective of what the change was.
TBH I think there is an unfortunate perception that every piece of gear is pitted against each other in this hobby. Not everything is a “giant killer” that “destroys” what you had before, that’s YouTube thumbnail nonsense.
