Keep in mind this is tvrgeek’s opinion. He is not a degree’d engineer or scientist nor has he published papers in technical journals on this subject matter. Therefore, he is not a subject matter expert. Correct me if I’m wrong. Treat his opinion as such.
I am not a subject matter expert on the internet or ethernet either. I have an opinion too. My opinion differs greatly from his. My opinion is based on personal experience. I am however an experienced, degreed engineer. I understand the value and context of measurements and how to interpret them. I also have 44 years in this hobby and have experimented and trialed various mechanical and electrical upgrades with varying degrees of success as well as participating in the observations and discoveries made by fellow audio hobbyists. One of the craziest tweaks still that I have encountered in this hobby is using a bulk tape eraser on CDs. It works, my fellow audio friends have experienced it as well. No one can adequately explain to me why or how it works. Doesn’t matter. What matters is the application and the repeatable results with a $20 Radio Shack bulk tape eraser. The experience is like hearing a record with a poorly tracking cartridge before the CD is demagnetized. After demag, the sound is much clearer. One day someone may figure it out but since the CD era is about over I think it is not likely.
