How do I know if my systems any good?

Myself being 40 years into this rabbit hole ,is never ending for example 

streaming and digital has increased dramatically in musicality the last 3-4 years 

that’s where IHave seen improvements that = or better good vinyl 

but at a cost with all Ethernet cables ,usb, decent quality Ethernet hub ,and dac power cords , well over $10 k to truly get that you are there , that being said your speakers, electronics,and cabling need to be respectable minimal $20 k

a good Audiophile average around $40-$60k for Audiophiles for over 20 years.

I am currently working on my end game system in That range over the next year or less.

My end game i own it and cost me 600 bucks... And i dont say it is an endgame lightly... It lack nothing... It is an headphone system for sure now... It can be improved at the cost of adding between 10,000 and 15, 000 bucks and would became  then competition for most high end system... I dont understand the fixation on the gear price ... Acoustic and psycho-acoustic experiments matter way more than investment in costly high end gear... At least in the S.Q./price scale ratio...

You’re the judge! You can compare it to other systems that you’ve heard, but ultimately it’s up to you. +1 @jeffseight if its like that, non fatiguing, enjoyable!

Suspension of disbelief:

That moment in time when you "disbelieve" that you're listening to an electromechanical simulation of a recorded performance and "believe" that the musicians are in the room with you.
