What are you using as a streamer? Constructive feedback please.

Then could you diagnose whatever is wrong with my ears.

Believe it or not I use an LG V 30 phone plugged directly into my amp. It has a quad dac and I hook it in with a nice quality audioquest cable. I use Amazon hi Rez and it sounds great. LG V series phones all came with a hifi quad dac built in. They are all discontinued and can be picked up used for a few hundred . It works very well.

Maybe this can be helpful. A real broad survey… with some of the good stuff at the end.

@audiophile7605  +1 to your post. Phones are overlooked and vastly underrated as a front end streaming/player platform. 

I encourage you to take the next step with your LG (...bypass it's DAC) and add a small form factor player/DAC/amp for comparisons purposes. Easy to do and you may be really surprised and pleased with the results.

I am considering a power supply board and linear power supply from PD Creative.in my Node 2i.  About $280 from Poland.  Can't play with the big boys.
