PS audio P600 in multiwave operation

With respect to the SDS, it has its own regenerator and shouldn't be plugged into anything but the wall. I have my tube phono stage plugged into a P300, but it tends to squawk (power supply transformer noise) with most multiwave settings. Frankly, I prefer the sinewave setting anyway.

I agree with Dopogue. I own a P-300, and the multiwave is just a bunch a snake oil. Sure, there are the subtlest differences, but they are only differences, not improvements. However, I REALLY like the basic Powerplant platforms and would recommend them to anybody!

When you operate the SDS plugged in to the PS 300 or 600, It should not operate on multiwave mode, just the very basic mode.

I like the Power plants well enough in certain applications my self. I owned a couple of PS300's, and did also have problems with "transformer buzz" and such from certain pieces in multi-wave settings! The Sinewave is the most trouble free. I could however see that certain systems (as is) do sound better with multi-wave going. Depending on overall balance and components used, there could be improvments to sound using them. I guess it seems it depends on your system.
I always see different settings at the "Shows" everyear. So that's that I suppose. I have also often been concerned about any problems the multi-wave settings might pose on gear, buzzing and all. Hummmmm
