Nobody disputes that you believe you can hear a difference between WAV and FLAC. You clearly are convinced.
But you are trying to explain your belief as a fact. To do that - you have to prove FLAC sounds worse than WAV. That might be possible. After all you are not trying to prove a negative. But the proof has to be reproducible by other people, otherwise, it's just a belief that only you have.
Worse - the approach you are adopting is wrong. You are jumping from what you believe you've heard into assigning your perceived degradation on greater processor noise. The problem with this is - It's clear to me that i know 10x maybe 100x more about computers than you apparently do. I'm not the only one. Others have also tried to help you research the knowledge gaps you have - the advice they have given you is correct. Basically, virtually every statement you've posted about why FLAC is poorer than WAV is total nonsense. You need to spend a few months or years studying this so you are in a better position to prove your belief about FLACs sounding worse than WAVs as a fact and not something you believe you have heard.
