I just received my GG Revelation ICs a couple of days ago and they are still burning in. I do agree with most comments here (and John's for the most part) as to the sonic quality of the GG cables based on my experience with the Extreme. I can also respect John's opinion. I have not heard the Jade Hybrid, but have heard the Vermeil (I'm probably one of the few who returned them).
I think the Jade Vermeil is a great cable and I believe John describes the sonic qualities accurately. However, in my system and based on my tastes the Vermeil did not beat out the Oritek X-2, and in fact in comparison lacked that little extra sparkle on the top end. When I got the Extremes and they were properly burned in they beat out the X-2.
I did notice a slightly wider and taller soundstage with the Extreme cables. However, my room size and dimensions have always caused soundstage issues. So could the soundstage be much wider and taller as some report? Possibly, I'll never know until I move and have a more appropriate listening room. I do know that the GG cables agree with my tastes and I'm anxiously awaiting the burn in of the Revelations so that I can better evaluate how they sound in my system. So far initial impressions are favorable.
