Gabriel Gold IC's are they really this good?

The cables really take about 250-300 to fully break-in.
The cables do experience sonic changes at about 40/100 and 150,however at about 300 hours you have EUPHORIA

What actually is changing from 150 to 300 hours? Are we talking tonality changes as in a more linear tonal response or simply a more extended frequency extremes, or .......... some other sonic attributes?

There's a lot of discussion on tonality here. This was not much of an issue for me at 0 hours or at 155 hours. Tonality was nearly identical to the Jade Hybrid except for a little bit of bass shyness in the GG Rev. I too never heard any hint of brightness with the GG Rev when used between the Aesthetix Callisto, CAT JL-3 and APL Denon tube CDP products.

What about dimensionality, decays, harmonic structures here? And I do not mean in absolute terms but relative to how the cables were from the start AND directly compared to other cables swapped in and out right then and there. I heard absolutely no improvement here from 0 to 150 hours. Are there any significant improvements in these areas at the 150-300 hours? And did anyone have a reference cable whose strengths excelled in these areas to compare back and forth with the GG Rev's during their burn-in process?

Soundstage,depth of field,height of stage,detail,bass and even greater tonality and textures which these cables are becoming famous for occur after the 300 hour mark.As I initially stated when I started this thread I was comparing the GG Extremes to both the Stealth Indra and Siltech Forbes Lake which are both what I call pretty decent reference cables.I liked the Gabriel's better.The Revelations definately take longer to burn in but once they do LOOK OUT ! it becomes NO CONTEST.
I've read a lot of Steve's feedback (sts) and many members love the sound of the Revelations right out of the box.I'm sure once they break in they must be gushing with greater appreciation.

Yep.

clio09-I assume you must have some?
What cables did you compare the GG's against before you went with them?

Bobf - I have two pairs of the GG Revelation. I posted a while back here on some of the cables I have directly compared them to including Oritek X-2 and RSAD Poiema!!!, as well as the Silver Reference II cable offered by Audiogon member quackfat.
Indirectly, I made some comments as to my preference for these cables over the Jade Vermeil and Virtual Dynamics Master.
