These waters flow with our liquid mids.

You aren't missing anything sound wise. Keep in mind the factory cable is only 32 gauge copper (really nice and flexible); I think we can agree the world class engineers at Sennheiser know what they are doing. The difference in impedance can't be more than .1 ohms (between what you have and some silver conductor cable or whatever insane nonsense) and this is honestly negligible because it is in series (adds to) the driver's impedance which is 320 ohms or more.
To compensate you could just turn the volume up ever so slightly if you want to hear what you are missing...
Your attempt at a logical correlation between the quality of the HD800 stock cable and the quality of the engineers at Sennheiser is a false proposition. You assume quality is the only design parameter. Certainly they could design a better cable if they wanted to, but they have to consider other things like cost, construction time, supply chain availability, sourcing, etc.
Secondly, the cable's resistance is not applied to the headphone's resistance, it is applied to the load from the source. If the source is 1ohm and the cable is 0.1 ohm, you're essentially only getting 90.9% of the source signal. Drop that down to a 6ft 10AWG cable (i.e. 0.01 ohm) and you jump up to 99%.
Third, insertion loss is not uniform across the frequency spectrum, so you can't just "turn it up", as you say. It will affect all different kinds of variables from FR, to soundstage, to imaging clarity, bass impact and more. It's not insane nonsense, it's basic math and science.
