Jafant - These cables have just been released and as such there has been little time to compare them to any other manufacturers cables in a side-by-side comparison.
But in the past I have assessed other models in the gZero line-up to be superior to some products from the following companies ...
- Kimber Kable (IC)
- Cardas (SC)
- Purist Audio (SC)
- Tara Labs (IC and SC)
- Stager Sound Systems (IC)
- Van den Hul (IC and SC)
- DH Labs (IC)
Also, here are some observations from another gZero owner ....http://www.audioasylum.com/audio/cables/messages/16/167504.html
The improvements between one gZero model to the next in the product lineup were not "marginal".
Hearing the zFLOW cables in my system, compared to the gZero20 IC and gZero6SC cables, one might consider them to be in the realm of "diminishing returns", but they do improve over time and the realism they convey is outstanding.
However, I DO NOT BELIEVE my system is capable of resolving to a level that would allow the zFLOW cables to demonstrate just how good they really are.
For people considering these cables - how do you choose?...
The gZero3 IC or gZero6 IC and gZero2 SC are perhaps the best "bang for the buck" for someone who may consider trying KLEI products for the first time.
The gZero20 IC and gZero6 SC is a superb combination for systems like my own, having (what I believe to be) mid level resolution capabilities.
And the zFLOW products are best suited to systems capable of even higher resolution than my own.
But then - I'm very pragmatic, but for others participating in this hobby/obsession - that seldom counts :-)
Having said that - when I purchased the gZero6 SC's, I moved the gZero2 SC's onto the L/R channels of my 15 year old Denon AV receiver - the improvements were immediate and very dramatic
A veritable WIN WIN :-)
Hope that helps
