I do not have experience with Shunyata power conditioners, but I have owned Richard Gray products for several years now, so hopefully I can shed some light on these - as I understand them (someone please correct me if I have this wrong).
The 1200S/600S (and the 400S) contain large 6H inductors (the 1200S has two) that are tied from the hot to the neutral lines of your incoming power. As such, they hold the power line voltage at a constant level, and will shunt noise to ground before it enters your equipment. Because they are not in series with your equipment, they do not restrict power.
The Pole Pig and SubStation do not regenerate power. They are isolation transformers which break the ground connection and create balanced power to your equipment which greatly reduces noise.
I use the 240V SubStation on a dedicated 240V line with an isolated ground, followed by a 1200S and a 400S RGPC (each connected to the SubStation) on my 2 channel system, with the power amp and preamp plugged into separate sides of the 1200S and the source equipment plugged in to the 400S. This has produced outstanding results for me. If I was to add another type of power conditioner, such as the Shunyata products, I would put it between the RGPC's and my equipment. Of course, this is based on speculation because it really requires some trial and error to see which sounds best, which is how I arrived at the configuration I currently use with the RGPC's.
I hope this helps. :o)
