Just a bit of history. That initial review was even quoted by PS Audio in their firtst Stereophile ads for the P300.
I initially used to PS Audio P300s in my home theater system - then bye bye P300s for two P600s. I was using two P600s, which were Bybee modded with multiple Bybee filters on AC inputs and outputs. One P600 was for front end components (excluding amps and sub amps). The second P600 was for my Dwin HD-700 CRT projector, Lumagen VisionPro HDP video processor/scaler and Extron video switcher. I used the 60 Hz sinewave on the first P600 as for audio I couldn't hear an improvement using any of the multiwaves. I used the P1 Multiwave square wave on the 2nd Pp600 as it clearly gave a better video picture.
Now, almost 7 years later, PS Audio has come out with its new Power Plant Premier (PPP), replacing all of their prior Power Plants which are now discontinued but still loved.
My first Power Plant Premier arrived Friday. I got it in that day. Here's my initial comments:
On Friday by mid afternoon I installed the PPP, replacing both of my P600s. I installed it in a 20 amp, 10 guage wire circuit; using a PS Audio Soloist; then an external Bybee AC charger; then the PPP.
Thanks to the PPP's 5 isolated zones, I plugged my Theta Casablanca 3 surround processor into one zone and its Theta Six Shooter analog multi-channel preamp into another zone, isolating them from each other!!!!
After about five hours burn-in: Initially, it really sucked big time, no dynamics or microdynamics, bass was dull and lifeless.
I was wondering - Gee, did Paul use Class D amps in this thing, is that why it sucks? But then I read the PS Audio website that Paul kept the Class AB amps, just that PS Audio found a way to lower the large power supply voltages so the amp was efficient 85%, by moving the entire power supply up and down in lock step with the sine wave generator, so the voltage across the amp is only what is needed, thus increasing the efficiency.
Let it burn in while sleeping. After waking up, after ten hours burn-in - WOW! Never sounded this good, particularly voices. Multi-channel SACD is clearly its best ever, bass, highs. If I turn it up somewhat louder than normal listening levels, its not quite as smooth as before, somewhat straining, but my experience is that with more burn-in this will be alleviated.
My good friend Lon came over. He's very familiar with my system. Took him all of a few seconds to hear the improvement. Note this model only has one Multiwave - which I understand is the square wave - and the one 60 Hz sinewave mode. I don't know that it sounds better than my P600s using the 60 Hz sinewave mode. But the multiwave mode is a clear sonic improvement - immediately discernable.
I am running all of my components (except amplifiers) off this unit now - and selling the two P600s. The top of the unit is hardly even a bit warm. Amazing.
Video looks just as good as before. But so far, haven't notice any difference using the 60 Hz sinewave vs multiwave. Looks the same. Which is fine, as its just as good as before. And as audio is clearly even better using Multiwave, I find myself using Multiwave always.
The product is simply amazing. And the prior barriers to many folks considering the Power Plant, Size, inefficiency, limited power capability and heat, are now a thing of the past. Amazing, Amazing, Amazing. And of course the $2,295 retail price for this is Amazing, Amazing, Amazing!!!
