I have just sold the HE-500s, but I still have 3 aftermarket cables for them, all are in pristine condition.
The cables I have are:
- Toxic Cables Silver Poison - $220
- Forza AudioWorks FAW Noir HPC - $160
- Artemis Cables Silver Cable - $100
I'm not sure if the Artemis Cables one is silver or SPC, hence the low price. It has a ton of detail and sounds a little brighter than the SP, so I think it might be pure silver. $480 is you just want the headphone...
