I have the 400S that I’m very happy with, except it’d be nice to have some more oomph on the bottom end (maybe shoulda got the 400i???). I too was looking for some better yet affordable cables, and although I haven’t purchased them yet I’m looking at the Satin Audio Hyperion 8. This is a double run of the standard Hyperion cable but still “only” costs $100 and is silver-plated copper in a Litz configuration. Just another option.
High quality headphone cables - HiFiMAN HE-400i
I just picked up a new HiFiMAN HE-400i headphone set with the 3.5mm connectors. While the supplied cable seems adequate, as with all things HiFi, I’m looking for a more robust, higher quality cable set. Does anyone have any suggestions?
