Power Conditioner

I currently have a Torus RM20 power conditioner. Has anyone compared the RM20 to any Shunyata or IsoTek power conditioner? What Shunyata or IsoTek power conditioner do you recommend I compare to the RM20? Is it better to have one power conditioner for lower power components and a separate conditioner for the amplifier?

Hello, Can anyone tell me what it means a green dot and/or triangle on a power conditioner outlet?

Thank you.

I've gone from a Running Springs Haley, Core Power 1200 Audioquest 1200, and now Puritan 156. Been happy with all of them.
