Any comments on Synergistic Research Atmosphere

Can the lead that needs the be grounded from the interconnect be plugged into my power bar, or must it be the wall outlet?

@riverboat. The answer is No if the same power strip also has the Atmosphere plugged into it, but yes if the power strip is on a separate leg of the same duplex as the Atmosphere power supply and is shared with other components. 
It’s easiest to think of it this way. The At,o sphere should always be connected to a duplex outlet with one connection (power) to one half of the duplex and the other (ground) to the other half.  Either half can share the connection with any other components without concern.

hi folk. my question this time was about the grounding cable that comes Atmosphere level 2 interconnects that are not actively powered. In this case could the lead be connected to my power bar?

So in the case of grounding connections to cables the same logic actually applies -- the ultimate ground should be on the same spur as the components but not the same outlet. It will work if you just plug into the power bar but it will sound better if the ground connection is not shared with any active components at all i.e. dedicate a power bar just to plugging in all of your grounds and have this connected to its own socket in a duplex. 

Thank you folk, i wish i had more outlets in my room. Oh well.
