OP,
Just my opinion and may Not be applicable to you, just me
I believe you (or anyone else) may have reach the point of knowing that your gear is at its peak and what you hear is the best sound quality you are aspiring for. for the price maybe that you are willing to impart.
Just a background, I started this HiFi journey when Covid started. I did not really know what true good sound is other than what i heard from numerous concerts, operas and live shows i have been too, other than being loud obviously, i can hear each instrument as they are being played, or singers as clear as they can sound.
So, I endeavored to replicate this at home and no way I was able to do it, except making thing loud. So, I relied on the opinion of others and Reviewers and statistically gathered all and made some conclusions. I listened to equipment and with generous return policies during covid, i tried numerous models because i had time at home to do it. (I cannot believe how many times I was at the Post office or UPS) returning gear, as I journeyed, I realize that some equipment sounds good to my ears but has a so so reviews and some gear sound OK I think but has a lot of good reviews and Reviewers uses them as their referent gear.
Ultimately, I found the gear I wanted and importantly, it has synergy. With this said, I can now learn what is it that most audiophile generally want in their music and magically the Lightbulb lit in my head!! So, this is what I am missing after all. It’s not too far from what i wanted to do or attain, making it sound close to what I heard in actual venues. but there are Compromises and that is what one has to live with
At this point, I know what Quality Music is. I stop obsessing over it, because the next level up is beyond what i can afford. So, I just enjoy the music. The fun is listening to OLD Vinyl recordings. that is truly where I am right now. as I can tell myself, THIS is what music as recorded and played back sounded in the good old golden years.
Enjoy the music and be Happy
