The PS power regenerator is the biggest gimmick on the planet. It's totally totally unnecessary and actually uses a lot of electricity when it's just plugged their waiting to be used. Spend a lot of money just keeping this box plugged into the wall over the course of a month maybe 25 $30 a month because it's 100 W continuous before it even does its thing to power your equipment.
You rarely hear comments about how it's improved and enhanced sound.
I use a Power isolator from transparent to reduce interference along the powerline and it seems unrestrictive and I can put lots of stuff on this thing. I think this glorified power switch I use is helpful and it makes me feel better.
