^ yup kasi electronic signal is electronic signal...and AFAIK this electronic signal will drop or will be affected if you are running the cable at long distances wherein the wire becomes a "big" resistor and weakens the signal and/or the wire is subjected or pass-by another electronic field (magnet or something of similar nature).

sana dun sa merun "high-end" component cable, mag-testing naman kayo ang shed us some personal evaluation....i'm really very curious dito sa phenomenon na ito.

baka kasi another marketing ploy eh...
