I should say straight off that my reference cables are all High Fidelity Ultimate Reference. I have never heard any cable that gives me the realism that they do. I have had both the Stage III Krackens and the Goebels as well as another prototype that I cannot mention. My system remains all HFC.
What I find absent in the competition is decay of notes and the realism of the performance. As Cam_01 says, the Goebels are quite mellifluous. I could listen to them all night, but they never give me any sensation of being at the recording venue. I fully concede that my personal tastes are such realism. This is just my two bits.
Just read up a few reviews of your PCs...impressive. Will look further into them when i can. Meanwhile, enjoy...they seem to be some pretty serious stuff.
