Transparent cable company offers a network box as part of its cable. it Adjusts the frequency range ever so slightly where it emphasizes those frequencies that are negatively impacted the most when sound travels through the wires.
It sort of purifies the sound and avoids impact by the wire that otherwise occurs.
It's a good cable company on the pricey side but Worth a review.
I have several of their cables and I'm very comfortable. They also do well insulated power cables.
