I have the 800s. Since everyone strongly suggests using balanced cables, I ordered a set from lavricables. (I think @soix had recommended them). Their website has many options, and the guys at Lauri were great at answering all my questions. I ended up with silver cables, balanced. I could not be happier and I highly recommend them.
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?
