If you look here at this photo you will see the plugs don't insert all the way. (that is the same cable maker / plugs)
Unless he's adjusted them, you can msg to ask.
See the gap? You can also see the member used an o-ring as a spacer and seemed to enjoy the cable quite a lot. I enjoyed silver plated cable on H-200, and there were some pure silver cables and variations floating around.

But the alternative cables were only a limited run, was a case of launch them too late. There was a lot of interest for upgrade cables from T-Peos for H-200 but they took quite a while to come with solutions. As things move rapidly on Head-fi their announcement on the cables was a little past the demand deadline.
You can try the Sunricky cable if you like but really if Its for H-300 I didn't like the results perosnally.
Take it with salt grains and a big YMMV.
