P20 revelation: sine wave over multi wave

WOW, after running my P20 the past 2 years in multi wave for most of the time with varying success I switched to sign wave and had my biggest improvement to date. Reading the manual, reviews and forums I thought multi wave was the way to go, but when I switched it to sine wave everything came alive. You could say “now it’s gelling. Too much emphasis is placed on multi wave especially here in the forums and manual.
With this type of product and its sophistication a more in-depth manual is needed to clearly explain differences in functions and usages. The manual doesn’t do this. Only a brief summary of each function is described. Success is only gained by knowledge and not knowing leads to frustration.

It all depends on how the gear connected behaves with each. Just this morning I flipped blind between SW and MW as I recently replaced my amps with a new one.

What do you have connected?

What is the manual supposed to say? “hiendmmoe will find Sine better sounding than Multi-Wave”? :slight_smile: Experimenting is how we find what works best for our systems and tastes. I think the manual explains the situation well.

Have you played around with Phase settings? That was the surprising setting for sonic differences for me and my P15.

First, the P20 isn’t a toy, so suggest just play around with it to find what works best is kinda foolish. As to the manual and functions a more in-depth analysis of what the function actually does.
Take for instance the word multi-wave used to describe a function of the unit. What’s does it mean and do? When to use it? How does it work?
There are way too many function settings in this unit not to have a full understanding of their PRO’S and CON’S. Anybody who thinks this is foolish to think you need all this info probably never reads their manual’s in the first place.

But you can’t hurt anything by simply playing with the controls on the Power Plants. That’s one of the cool things about them. Nothing will break, only change or not.

And I’d argue it is a toy mostly for big boys.

Sine/MW is not distinguishable in my system, nor is any level of MW but adjusting the phase to better match the incoming mangled waveform improves sounds and distortion readings.

I agree that many PS Audio manuals need help; some REALLY need help.
And I agree with Brett that SIne/MW has no influence that I can hear.
And also that you should definitely play around with it. Many users hear big differences and you might too.

I shared similar sentiments with respect to sine being more focused and multi being warmer and diffuse in my system.

I hear greater differences toggling the phase option on the DS than Sine/MW. Maybe if I listen very closely I hear something changed with the wave (and it’s blind for me, as I can’t see the unit) but absolute phase is much more significant and quite subtle at that.

Well I think the manuals definitely could be improved, but for me they give me enough information to get going and hands-on experience with them teaches me what they can and will do. The manuals are functionally sufficient for me. YMMV. I’ve had power regenerators from PS Audio ever since I first pre-ordered the P300 before it was released.

I hear differences between Sine and every level of MultiWave. And phase is intriguing to play with. I usually end up listening mostly to MultiWave level 2. And If I do “AutoTune” the P15 usually puts me at +5. It sounds more than a little edgy to me there. I usually listen at 0, sometimes on lesser recordings -1 or -2.

the manuals need some severe help with the power plants

That’s pretty much true with all of them and I own four different pieces.
