Post Subject: Always I use only one pure powerPosted by Amir on: 12/7/2021
Romy , you are right , pure power affects on wall AC quality, when a pp3000 is connected to wall ac (the TV not connected to PP3000) then the picture quality of my TV decrease. 
allways I use only one pure power 3000 and other pure powers are disconnected from AC (all are off in their boxes).
one month ago I just had a test with three pure power in my room , the building ac is 3 phase (120 degree phase shift) and i connected three PP3000 to three different phase to check the macro dynamics. Pp2000 -> cdplayer/prePp3000 (1) -> left monoblock amplifierPP3000 (2) -> right monoblock amplifier
The sound was not good but the macro dynamics was better.My monoblocks power amplifiers are rated 350w/8ohm and 700w/4ohm. Speaker is 4 ohms. Power amplifier is fully balance .My system does not have earth connector in input AC plugs and all the system is fully disconnected from ground of pure power.
