Yeah I have to agree with the above, have fun, look at reviews and demo if possible, but ultimately you'll have to take the risk of buying something. Generally speaking I haven't hated any upgrades I've made, it's all in the pursuit of fun and learning in the hobby.
Also you've got to learn to be happy with what you have, which sounds like a cliche life lesson, but it's really true, and
@displayname hit the nail on the head in this regard. I'm in my 20s as well, and recently back to a single income household, and I have other hobbies than this, and expensive rent to pay in an overpriced city. At this point the next major audio purchase I'm going to make will be a new stylus for my cartridge later this year, as part of general maintenance. I came to this conclusion a few months ago that I was happy for a good while, as a few years ago when I was still in college, or a few years after that digging myself out of debt, I would have been thrilled to come home to this system every day.
Earlier I asked if you had a particular thorn in your side because I knew mine was tracking, which I was able to solve via a cart upgrade, which was money well spent because it was one thing that annoyed me whenever I played a record. A simple practical fix to make. This may sound a bit harsh, but if you just keep chasing upgrades because you don't "enjoy music" anymore or feel its impact, due to some general state of malaise with music you're not going to crack that. People enjoy music everyday on Airpods and BT speakers, they're not encumbered by the baggage of this hobby. For me I stay in this hobby to enjoy music
more, not as a pathway to enjoy music period.
