@dbphd I would highly recommend you purchase quality aftermarket cables instead of building your own. There should be a number to choose from, like Arctic Cables, Norne Audio, Moon Audio and others. The headphone side connectors are a royal pain to assemble since there are multiple pins and they are small and very close together.
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?
