I wanted to share my experience with switching to the Graphene Matrix/Extreme from Nordost, Audience, and PS Audio.
After a fellow audiogoner who is local to me told me about Cerious Technologies I reached out to Bob to ask some questions about the product(s) and he was very ease to communicate with.
My original intentions were to replace some tired PS Audio Signature speaker cables.for context I had demoed in my system Nordost Frey II and Tyre II.
I placed and order for 10' GM speaker cables and decided to try 1.5M RCA GM interconnects which would replace my Audience AU24's between my DAC and Integrated. I am fortunate enough to be 30 min away from Bob so I was able to pick the cable up directly.
I should note that I am sensitive to overly forward or tipped up presentation so I always have concerns when I here words like "resolving and transparent".
The first few hours in the system had me concerned the GM's for my ears are a little hot... That being said the best advise I can offer is LET THEM BREAK IN without moving them. You will be rewarded for your patiences. In my system the first 20hrs got me 50% there, 80hrs about 90% there, and I have heard much change after 200hrs.
In comparison to the Frey II and the Tyre II, they have a more balance presentation and less emphasis on micro detail. This isn't to say they are not detailed I just simply mean that the Frey and Tyre overly emphasize micro detail to the point where they are tipped up a bit in the upper mid and higher frequencies.
I have been fortunate enough to listen to the cables with Arcam A32, Luxman 590AX II and D-08u, Aqua Formula DAC, Meridian DAC, Jolida 202A, Line Magnetic 210IA all being sent to Golden Ear References and powered through Nordost QX4, QB8 and Nordost Frey II power cables. I always allow 3+ days for the cables to settle back in.
The results are always the same. Balanced tonality big wide and deep soundstaging, well articulated, and great texture to vocals.
Now I have purchased 2 10' GE power cords for the Golden Ears and 2 GM to replace the Frey II's coming from my wall outlet to the QX4 and from the QX4 to the QB8 (5' and 3' respectively). When I picked up the CT power cords I was demoing the beautiful Luxman 590AX ii and the Luxman D-08u with a Nordost Valhalla II power cable from the wall to the QX4. I placed all of the CT power cord into my system and out of the box the GM sounded really good, not as well put together as the Valhalla sonically but the Valhalla was fully broken in. 20hrs later I just left the Valhalla out of the system the GM's were just hitting the mark and were besting the Frey II power cords with a more neutral tone and expansive soundstage and really close the the Valhalla. I have about 130hrs on the power cords now and feel they are fully broken in. I am very pleased with experience the CT cable are giving me.
One last point to make is these cable are large in diameter but with well thought out routing and purchasing the proper length for the chosen routing I have found no issues with the diameter or flexibility of these cable.
I hope my experience helps anyone who may be on the fence about these cables.
