Throughout my HiFi journey, I have been amazed by relatively low cost components several times. My little Dragonfly and PSB headphones provided and unbelievable upgrade for computer listening, which I did at work.
That was 500$ very well spent.
Then I moved on to my A&K with Grado headphones, another big leap. $1700.
Now I have a dedicated listening room. After going to shows and every dealer in the area. I spent 14k. IMHO, I would have had to spend tens of thousands more to get significantly better sound. At the show that I attended, one of the standouts was a system with a HiFi Rose all in one with Piega bookshelf speakers. That system was just over 5k. With a good sub, In hindsight, that system may have been good enough for me. But I definitely love what I have. Everyone that hears it is flabbergasted and wants more.
I am also well impressed with my little “The Fives” by Klipsch that I have in my living room. They fill a wide open space with clear and powerful sound. And that is just over Bluetooth or the TV’s ARC out. With a really good source and sub, I could see that little system being enough for a lot of people.
Sit back and enjoy what you have. The smile on your face is all that matters.
