"I know it is possible to get a clean, neutral yet natural analog-ish sound if the cable is done well. Does the G6 Golden Ridge fall in that category ?"
--Yes, definitely. Quiet, natural, and resolute is how I would describe them. I do not think even their G5 have what you would call as loose bottom. Albeit neutral, they have ways in rendering digital more listenable--organically musical.
SATT is Siltech Advanced Thermal Treatment where they supposedly fry and freeze the cable. Introduced in 2006 as their new metallurgical treatment method. I heard subtle but noticeable differences between their SATT and non version in my system.
