Sure. I assume you mean setting up the VTA… etc. We are all guessing to some extent. Hoping to identify the weakest link that will bring the greatest improvement for the investment.
I guess one of the best things is that even if you identify the wrong thing and upgrade something that is not the weakest link, it’s still going to sound better. Provided you don’t get something that is just plain not to your taste or is incompatible, you win. Next upgrade you’ll probably pick that one and get a really big gain.
