not that i've heard of. you do not need to spend the 100 bucks the guy at best buy tells you is the best cable you can get. i spent 10 bucks on a 15 foot cable to run to my tv and its just fine.
digital signals like hdmi do not suffer from signal loss through poor shielding and interference. they're transmitting 1s and 0s, not an analogue signal which can be degraded by similar nearby wavelengths.
could you explain your issue in some more detail?
