Harmonic Technology Cyberlight cables

Mystery humm cleared. But still strange.

I am using a APL 3910 direct to my Krell Amp.

I had a Composite Video (RCA) connected to the APL and then to a small TV so I could use the TV when playing DVD-A's while navigating thru the menus.
Once I disconnected that RCA Video connection the humm went away.
I still think its strange though since these cables claim to break the grounds that this video connection produced the humm and it was only in one cable.

I haven't had any problems with mine. Try a new set.

WOW, one year warranty?!!! Most cables are lifetime. I am not sure if I want thousands invested and have possible problematic cables. My components have better warranties.

I totally agree a one year warranty for such an Investment is way too short!
The Power Pack (+$399 Option)contains a special battery and charger for running the cables straight from the battery.
Now the battery life must be limited and problably hard for the consumer to change. The charger could malfunction.

With such a short warranty, how will the resale value of these cables hold up? Will it be like buying a used cartridge (ie, something that has wear and a lifespan) on audiogon?
