Back when G5 was their current top model series, I used their Compass Lake top model interconnect. They were outstanding. They easily outperformed the Nordost Valhalla in my system at the time. Valhalla was Nordost's top model back then. The only cable I could find at that time which matched or surpassed the Compass Lake performance was the Purist Audio Design Dominus RLS with the active Raidant Light System.
From what I understand the new Siltech Double Crown series is a big improvement over the previous G5, G6 and Royal Signature G7 series.
I also believe that Kharma use the same conductors in their cables as Siltech.
From my experience with Siltech they are very neutral, resolved and dynamic. They don't have the elevated top-end that the Nordost Odin has and less dark than the Transparent Audio Opus MM2.
Thanks,
