Fooling and forever trying to improve your system is what keeps this a hobby and a forever enjoyable endeavor. Once it's right, the time will creep up on you when you will again be looking for further improvement because it can always get better. That's how most of us think about our systems and why we stay interested and searching. It we once got it right and thought no further improvement was possible it would likely become about as interesting as a chair.
Cart adjustment, that moment when you nail it!
Dang, after futzing with my analog system, and getting it “ok” but with some distortion here and there etc, FINALLY got the thing dialed. All I can say is WOW... Lot’s of trial and error, tiny adjustments, etc. and then ding! Nailed it. Finally! Just awesome. If you are in the tinker mode, keep trying, you WILL get there. It’s worth the time!
