I have the powercell 10 se and formerly had the power plant premier. The ps audio conditioner was pretty effective and I was happy with it. But I did not dare hook my krell 650 monobloocks to it. I always wondered what it would do for the krells to have a conditioner that would handle the current demand. Boy oh Boy what a revelation!! It is worth having the powercell just for that reason.It is killer what it does for the system.The se has a bigger filter than the other two. I love it!
