Sennheiser HD 800 aftermarket cable

Meestickbuf, search "synergistic foundation" and sort by date, not relevance. Numerous mentions of Foundation series cables, although likely not in the headphone space. I developed these cables for my Sennheisers, because I love them and you likely will too after 30 days but if not, no big deal.

bslon, I'd say most of my listening is digital. I have both the Sennheiser HD 800 RCA and XLR cables.The RCA sounds pretty good directly connected to my DAC's HP socket but I'd like to get the best SQ possible Unfortunately there's no XLR input on the DAC and I don't want to buy a headphone amp. I prefer an XLR connection but if RCA sounds very good I'll be happy. ted_denney I'd love to give your Atmosphere's a try. I looked up Foundation series cables as you instructed. There's a lot of info on IC's, digital, power and speaker cables, but I still don't see any specific to the HP cables. Seeing you have Foundations and Atmosphere HP cables, what's the difference or improvement in sound especially with an RCA connection?

Atmosphere headphone cables were engineered prior to Foundation and is based on our Tricon geometry. As for the Foundation headphone cables, it’s a pure 6-9’s silver conductor in an air dielectric, 100% handmade geometry and terminated by hand in my Southern California factory and conditioned on our massive Tesla Coil. It has the same house sound as the rest of the Foundation Series, but in the case of the Sennheiser variant, is specifically voiced by me on Sennheiser headphones. Both are great but I’d likely go for the Foundation at this point.
