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?
I use the Isotek Evo Aquarius conditioner.  I plug both Canary monoblock tube preamps into it as well as my other equipment except for the transport and dac which run off battery power.  It is in no way current limiting to my ears.  The system sounds pristine with exceptional clarity and has great dynamics.  I just picked this conditioner up on Audiogon and could not be more pleased.  

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.
