Has a component ever changed your focus?

I’ve just made a change in my system  that changed my priorities. Swapping out a 2m black for a dL 103r.  Suddenly I’m listening to the music more than the system without having to think in such terms. 
Gone is the etched, hyper-detailed, scientific sound.... Instead, smooth, musical ease and emotional involvement. 
 Just as important, record surface noise has been cut dramatically. Opening up access to hundreds of LPs and I was reluctant play before. 
 And the new cartridge is still running in.
  I’m finding that after just a couple days, though collecting records was my favorite aspect of this hobby, now it seems to have so much more potential. I’m no longer thinking constantly of my next tweek.
 Has this happened to you? What component did you change that made you change the focus of your listening experience?
