I thought the stock cable was great when I had the HEK V2’s. I never felt the need to upgrade. The stock cable is a mix of silver and copper. So you’re getting the best sound out of both. I’m sure there are some aftermarket cables with different wiring patterns and cable properties that might net you slight incremental improvements but you’re gonna pay top dollar to hear it.I got my hifiman he1000 v2, and i love it.
I used the stock balanced cable with it to my chord qutest and ifi pro ican amp
Can I ask, do you think the stock cable is good enough or is there another cable you would recommend to use with it that is gonna make a noticeable difference
best wishes
For me the biggest improvement I hear is when I change DACs and amps. For me, a change in headphone cable would be the last tweak once I got my front gear all set.
