I would say it sounds like you have made good choices… because when you don’t you will know it.
Early on I made a few bad choices… although I may not have known it on the first day. One of mine was I found out what grain was in the sound of a used preamplifier. It took about three days after buying it to hear it… I could not unhear it. I lost a lot on that one… but I immediately had to trade in.
I always try to hedge my bets by always doing enormous amount of research and upgrading no less than 2x the investment. I don’t think I have been disappointed once I made sure I did both.
One thing is that you learn about sound and your tastes and over time will likely make different decisions. Often early choices focus on detail and slam and latter decisions are made on different less easily perceived parameters.
