ghdprentice said it well. I for one started this journey just at the start of covid and all I relied on was reviews and forums. I have always wondered, back then, was I hearing good enough. yeah, wallet say so, but was it good enough??
As covid subsided and more shows open up (and dealers) I took that opportunity to answer my questions. well, I found out that I was not too off tangent. we can go on and on, but for me, let me summarize it. You don't know what missing unless you know what you're looking for. And, you think you are right, but sometimes you are wrong.
needless to say, I thought my system is good and satisfying a couple of years ago, but after listening to shows and reading a lot on forums and finally listening to High end ($$$$$) gear, well, you will know what you are missing because our brain is telling us to observe (listen) carefully what a truly expensive gear sounds like compared to my home gear. As this discovery unfolds, then you now seek that goal but being realistic on your wallet.
You will eventually reach a point that your gear is good enough (again based on your budget) and that's where you can stop (if ones wishes). I check mine against top $$$ builds and my EARS tell me that I am close.
