I have 2 Purons and have just purchased 2 more. They clearly make a difference. The nice aspect is that this isn't one or the other. The Purons compliment power conditioners and work well as a stand alone. My initial two Purons went into the duplex outlet that my PS 10 power conditioner is plugged into as well as the first plug in line on the back, exactly as the reviewer above described. Not a small difference. My next two will go into the outlets my amps are plugged into. Should receive them next week.
@wokeuptobose I too have found the swiss digital boxes outperformed my SR purple fuses. I tried the Rhodium in my PS 10 and I think its the best of all of them.
