I'd much rather put $200-$400 into something like Toxic Cables or Double Helix Cables, but it's also nice to have an officail cable for the same headphone, so to speak.
That's the thing: People here who are going to buy an aftermarket balanced cable are going to get one from one of the small guys that doesn't have to double the price to allow for dealer margins, which is what I think is going on here.
