Ad010685 - The difference between these cables and most all of their competition is in their internal architecture
Most cables have a neutral and signal conductor of the same length laying side by side in parallel - parallel conductors promote noise, i.e. induced noise from the signal conductor into the neutral conductor.
Having any noise in the neutral side of a circuit causes distortions across the entire frequency range, which is subsequently amplified to audible levels.
The architecture employed in the gZero cables is a paradigm shift, in that the neutral conductor is wound around the signal conductor.
1. providing an effective shield for the Signal conductor.
2. since the neutral is wound around the signal conductor, effectively crossing the signal conductor at close to 90 degrees, it prevents any noise from being induced into the neutral conductor from the signal conductor.
Yes - they are all hand built cables - They are not bulk cable with RCa's soldered on the ends!
Using either a gZero IC or a SC will achieve improvements in performance - but using both will achieve significantly more.
Add to this the superb performance of the KLEI Harmony RCA plugs/Bananas and you have cables capable of performing to an extreme level of fidelity.
When I first heard the revised gZero2 IC I could not believe this was an entry level IC - the only difference between the gZero2 and the gZero6 is with the 6's there is improvements in high frequencies. And it just gets better as you proceed up through the model range.
When I first received the gZero2 SC's I was very skeptical, since they are very skinny, i.e. for speaker cables - but they were simply amazing - I've since upgraded to the gZero6 SC's, which provide an even deeper, but extremely well controlled and very textured bass.
I have no affiliation to KLEI - except to promote what I consider to be excellent cables that, when compared to the competition, are reasonably priced
My system is modestly priced, but using these cables elevates it's performance to a whole new level
At the end of the review below there is some more info on the effect these cables have on a system
