Let's see....$260 on two cables....that's called separating a fool from his money. Unless you lock yourself away in your personal studio and play alone all day and night, NOBODY is going to know a $130 cable from a $10 one, especially if there's anyone playing with you. Hard to believe a company can sell enough people on their BS to stay in business...
Think of it this way...accessories usually carry anywhere from 100 to 200% profit margin for a retailer. That $130 cable probably cost the retailer $50 tops from the manufacturer. Now take into account that at that price, it's not going to be a high-volume product. The manufacturer has to make money too, so their margin is going to be at least equal to the retailer selling at MAP. What you end up with is a cable that cost maybe $20 worth of materials/labor/overhead...and ask yourself if you can waste your money with a good conscience on something that you MIGHT be able to hear a difference with. Most likely the only difference you perceive will be the one that you want to hear to justify spending your money.
Just my $.02 =)
