Honestly I think half of the upgrades in audio are only our perception. Of course, if you use a HD800 or a Pro80 you
will notice a difference, but mostly because you
must notice a difference due to it being so big (I suppose, I've never tried the Senn). Now differences between a stock Pro80, a Pro80 with thick, velour earpads, a Pro80 with a fancy expensive cable, a Pro80 with a fancier and equally expensive cable that has a non oxygen retractable gold wire (whatever that is
), honestly, for me are too small to be that important, and the effect they have is mostly placebo. But hey!, I'm not saying this is a bad thing, perhaps it is even better because placebo is cheap. I'm just sayin'... more money =/= more quality, or at least in a way that is worth spending tons of money on cables.
btw, this is the only cable worth buying if you are a comuter: http://www.amazon.com/Scosche-IU3-5RC-3-5mm-Retractable-Cable/dp/B000ALY22Q/ref=sr_sp-atf_title_1_17?ie=UTF8&qid=undefined&sr=8-17&keywords=3.5+mm+cable
