Harmonic Technology Cyberlight cables

For those of you who have tried the HTC cables, tell me about the power supply. Has anyone tried both the wallwart and the high buck power supply? I did speak to someone who had some issue with the optional power supply but said the factory had told him this was being revised.

What's the experience with the power supplies?

These cables have been out for about a year now. I would like to here from people who have had these cables a long time.
How are they performing?
I know thre has been compatibility problems, but to those that did not have that problem , have you had any other problems?
Will they last for the long term ?

Beowulf,
I tried the optional battery supply and it was an improvement over the wall wart.

Another one bites the dust..................

I have removed all of my cyberlights from my system. They are too sensitive to voltage output and output fluctuations and are not stable....they are not plug and play without hassle. would not recommend these now.
