Synergistic Research Powercell - Does it compare?

I recently watched a video from CES on the S.R Powercell conditioner and wondered how it would compare to other brands(PS audio power plant premier, Monster, Shunyata, Furman.) How is it different in quality, noisefloor, protection??? I had a PS Audio Quintescence and noticed it limmited sound quality, as noted by fellow users with same experience. I do have a full S.R Tesla set-up with a Quattro(12BNC) and have recently ordered an S.R QLS 9 in place of the PS Audio. Would the Powercell be needed in conjunction with the QLS9??? Is the PowercelI a larger version of the QLS??? Any suggestions will be helpfull....THX....
