I am using this cable I recently got from lunashops. Fantastic sound from this cable. It is a bit heavier as the silver coating adds a bit of weight but worth it for the sound enhancement. Good deal imo.

Both sound excellent on the FX850. Even more detail, a touch more space. Sounds like an upgraded FX850 to my ears, Love the sound.
Thanks for posting this! I was curious about a good cable upgrade for the FX850! Even though I don't really need one yet
