For better sound than a Sennheiser stock cable and at a similar price, it would be far better to buy an after market premium cable from Moon Audio, ALO, etc. The Senn cable is ok but on my HD800 when I replaced the stock cable with a Moon Audio Black Dragon cable, the sound was significantly improved -- more detail, transparency and bass. Better overall.
I see no reason to ever buy a Sennheiser stock cable, especially at those prices.
Yes, my point exactly. The outrage over the Senn cables is about the pricing, not whether you should go balanced or just DIY. They should cost 50-90 bucks. They are stock cables. For that much money, you can get a superior balanced cable from not only Moon, ALO, but Forza Audio Works (if you're in the EU) or BTG here in the US. I have no stake in any cable company, but want to provide a few links because I think this is a giant rip off by Senn.
