Hasanlatif,
I don't use a Powercell, I use a Platinum Power PP-1 high current balanced power transformer on my amp, sub and phono preamp.
I run the Monarchy straight from the wall(Oyaide R1/WPC) and from there I power the MPC power strip and a Walker Audio motor controller for my TT motor. Like I mentioned, running the MPC's from the AC regenerator firms up the attributes of the active shielding on the SR cables. The Powercell does not address AC voltage or frequency flucuations and just passes what comes out of the wall through the powercell unit. The Monarchy AC regenerator specifically addresses AC frequency and voltage.
Cheers
