I've used Forza Audio Works and Norne Cables with great results. Both should have many options for different cable options, termination choices, maybe even colors, so you can find something to fit your budget.
Balanced wiring for Sennhesier 800 S
I expect to use Sennheiser 800S with my Ayre QX-5 Twenty, a Roon-ready DAC. As usual with Ayre, they recommend balanced cabling. Is that easy to do with the Sennheisers? I haven't used headphones in years, but I was impressed when I heard the Sennheisers with a McIntosh headphone amp. Any recommendations?
