take your server/player to somewhere where their is a high-end "audiophile" server/player, setup with appropriate highly revealing other components and cables and compare.
I believe I've already done this without having to take it anywhere. I've built all level of servers, from the AudiophileStyle's totally quiet fanless model with no moving parts and using the various OS tweaks that are/were supposed to bring OS operations to the quietest levels possible, to powerful beasts that may clearly have noisy electro-stuff. I mean, I have probably built 15 Roon servers. All flavors. The transmitter in a network configuration just cannot generate a different sound.
I've been designing and building media computers for over 30 years - I'm not just guessing here. What I don't have are the fancy milled aluminum parts to make those beautiful chassis. Please, don't tell me the chassis affects SQ!
In terms of resolving gear, I have Magnepan, PSB, KEF, Monitor Audio, B&W, Krell, Balanced Audio, Focal, Levinson, Classe, Bryston, Parasound, Wyred4Sound, Auralic, Schiit, and Mytek. I'm good on resolving.
You can talk about how best to catch a chicken but until you have experience catching chickens, what you have to say is mostly meaningless.
See above. By your analogy, I have caught a lot of chickens. I have been obtaining, churning, buying, listening, tweaking, all manner of resolving enough gear for a long, long time.
Music, like all art is personal.
Music is personal, for sure. What isn't personal is how IP networks function. What isn't music is what goes from the server to the streamer. It's packets of IP data, the same regardless of the sender.
This "my system is bigger than yours" method of winning arguments, well, just try to read it objectively.
