I have been told (directly, not third party) by one of the highest authorities at Denon Electronics that their cable is a shielded Cat5e cable... They only made it to satisfy custom installers who wanted something ridiculous to sell clients who had more money than sense. Off the record of course...
In this case Denon aren't bad guys, they just aren't stupid. They had enough requests and knew these guys would simply go elsewhere to get what they wanted (another product they could sell people who, if they dropped a $100 bill on the ground, would think it a waste of time to stoop over and pick it up).
In this case, the people at fault are the installers who can't seem to charge for their time and instead want to cultivate an industry where their services are "free" and everything is paid through them buying products at cost and selling them at retail to clients. The really big installers know how to run a business, but the middle and lower tiers are largely fueling customer ignorance of the value of their services.
Real Programmers don't write in FORTRAN. FORTRAN is for pipe stress freaks and crystallography weenies. FORTRAN is for wimp engineers who wear white socks.
