I've always had good results with this one:

It is better than german Sommer Onyx and Mogami Neglex (both being very good, often better than stock cables). Take a look at this guy's inventory as he also sells 8 cores version.
About that... Not that I'd like to start a flame war, but I'm pretty sure that what you've meant is that _you_ cannot hear differences
Having engineering degree in electronics and masters in IT I was also sure that basicaly all cables are created equal. Until I bought replacement cable for my IE80, which sounded AWFUL. Like a tin can without bass and badly distorted treble. But it
shouldn't, right? It
should sound exactly the same as stock one! That was kind of eye (ear?) opener for me and I started to experiment with my own DIY cables using different materials.
Now I know that as long as you have good enough DAC, amp, and headphones:
- thin cable will make power hungry headphones (regardless of their sensitivity level) sound artificial, with bass roll-off.
- thick, high AWG cable will give good bass extension, if too thick, there will be no balance with treble and the sound will seem to lack highs.
- regular copper<OFC<PCOCC - in regards to details and dynamics, though to hear that particular difference you really have to use good equipement and the differences - though there - are small
- silver plated PCOCC with high AWG will give best of both worlds: nice low end, well controlled and with good extension, at the same time providing natural, clean and airy treble.
- solid core is a no-go with headphones (kinda obvious
)
Thus my go-to cable is nowadays this linked silver plated copper cable. This particular one has also really good looks, though it is stiff enough to have some microphonics: but I do not use balanced cables on the go.
For connectors when possible I try to stay with Neutrik or Amphenol offerings, not because of any influence on sound signature (never experienced any) but for purely pragmatic reasons: they are wery well engeneered, they are really nice to solder and are sometimes reusable.
But in general: do not take my word for this: experiment on your own! It's simple and cheap, and you can get some splendid results without spending absurd amounts of money (cable price same as headphone price is a kind of monstrosity unless you have really deep pockets and like to burn money just for the fun of it).
Once again: experiment!
(another long one
)
