'Shunyata Research’s exclusive NR (Noise Reduction) technology is a multi-stage filter network'
The only filter I put near my kit are DC blockers. I took every other filter out because they squash dynamics. The Shunyata also uses brass connectors and brass is an awful conductor. Shunyata not for me methinks.
The current Tunami is heavily shielded UP-OCC which I think is higher grade copper than OFE. They are also known for having zero perceivable noise.
I also don't buy off the shelf cables- I make them with bulk cable and very good connectors.
