I put a link of fiber optic cable between my router and my music server. $70 investment. Ok, I also added a pair of $85 linear power supplies to power the FMC’s. I figured no sense adding noise back in with cheap wall warts. It made a significant improvement in the sound of streaming music. Is it a figment of my imagination? My cousin did the same thing on his system and was shocked by the improvement it made.
I would hope that people would get past the, "it’s just 1’s and 0’s" and come up with an understanding as to why it works. Then more progress can be made. But no progress will happen until we all move past the denial stage.
My internet still comes in on a cable- 500 mbs. My cousin has fiber coming up to his house.
