And why would you trust anyone but yourself to make that decision? If you cannot hear a difference sell it. If you can hear a difference keep it. it isn't as if you will lose much by doing so.
This is the problem with people and cables, the assumption that different is better. I think he got good advice. Choose your levels of distortion and RF intrusion somewhere else. Maintain the signal quality at least to the DAC. When you have EVERY piece changing the sound, then it’s really really really hard to tell when you do anything right. You need a starting point, and the cleanest digital is a great place to start. Then choose your distortions you like, choose SET’s, vintage speakers, diffracting speakers, whatever it is that you like the sound of.
Unless the routers are setup for shields and run balanced, then shields probably do nothing but warp phase. Unless the whole setup is made for something beyond cat6, and the features are standard, it’s probably a downgrade - but it might sound different!
As mentioned in another thread, I like the idea of using fiber to isolate, and then making the fiber reciever be super low noise. That to me is probably the best way you can maintain signal integrity and leave noise behind. Instead people are creating ground loops, warping phase, etc, to hear something else.
