P10 Clean function is amazing in my system

I’ve put together a large active system (I’m in a 240V country - I’ve had the system for several years and recently realised the dramatic affect the clean function has on this very revealing system). Within the system are a couple of P10s, three Direcstreams (seniors) and a couple of BHK250s (for mid/treble). There’s a digital crossover to provide Coax S/PDIFs to the DSs (there’s a powerful Crown amp for bass and massive PMC speakers).

I urge anyone with a P10 (or say 15/20) to use the clean function, along with MW6. You’ll need to do a thorough clean. I suggest the following:

BEFORE doing anything play a well recorded track to get a reference sound.

Set Multiwave to 6 then run long cleans for at least five times (5 minutes).

Listen again.

The difference on my system was astonishing - the sound seems slightly louder than before degaussing and everything is so clear and focussed. I was gobsmacked.

If you hear a clear difference I’d be interested to know:

  • roughly what your system is
  • what voltage your system is running on.

BTW, I find I have to repeat the clean function after just a couple of hours of use - a couple of minutes is sufficient unless I’ve let it get really bad (when I tend to do about four minutes).

P10 on 230V and frequent user of cleanwave too, no dramatic results but it’s noticeable (system in my profile).

You are right on with your findings…hadn’t thought of using clean wave
with a mw of 6…

I have used clean wave on sine and multi at 2…I need to give your advice
a go and see what happens…and yes clean wave crisps up the sq quite a bit
and run it at the start of each session and even at differrent times during
my listening sessions.

Thanks…

I have used the clean function at MW 6 many times but only for the 1 minute interval. I tried what was suggested and ran it 5 times in a row. I was very happy with what I heard afterwards and do not know if it is just the power of suggestion or that something actually changed. All I know is it does not cost anything to do and only takes a few minutes. A worthwhile tweek!

Another good idea run clean wave numerous times…
I’ll give that a go as well…never thought of that one either.

In my system, after a thorough clean, it was very easy to hear the difference between multiwave and sinewave. Without a degaussed system the difference was far less obvious.

Thanks…I find with some recordings multiwave gives lean sounding
music body and weight…but for most recordings sine wave is my
choice.

How is it with you for playback…any preferences sine vs multi?
And in you ears what is the difference?

Clean wave for me is like washing the car so to speak…cleaning the
house windows…

Have a great day!!

On my system Sinewave has better very high frequency delineation but Multiwave is more solid and the system sounds incredibly lifelike. I prefer Multiwave.

On my P20, I use sinewave for analog and multiwave 4 for digital.
Multi gives me more air and sounds more exciting, but at 5 or 6 it is too bright and etched in my system (DMP and Lumin U1, DSD Sr, Plinius Tautoro, 2 Plinius SA 103s monoblocks, and B&W 800 D2s).

Appreciate your replies…

danofesherintheuk…Sine wave delineates the hf but for me the mids as well…
what you found with Multi wave giving a more solid sound is my experience as
well but at the cost of hf and air…

It is good to know we share the same findings…though my overall preference
till now is sine…may change though as the SR Orange fuses allow for some hf
and air on multi wave to come through…so then maybe I may change my preference.

Phillipe…appreciate your experience as well…but am curious how Multi wave
gives you the results you are experiencing…

You have some top notch gear with your Plinius pre and power amps…and
B&W 800 D2s…

Are you running your amps in Class A or AB mode? Curious on the power
in watts is being "demanded by your Plinius amps on your P20, shown by your
watt power meter screen…

Thanks Phillipe

Happy trails

My system is in a large room (30’*20’*8’) with lots of absorption and bass traps to counter reverb times. The DEQX digital crossover has EQ as well as impulse response correction. Because of all the damping I boost the frequency extremes (and there’s a bit of cut to reduce lateral room nodes). When the system is ‘cleaned’ I can clearly hear differences in solidity (multiwave). I EQ’d the system using multiwave so Sine seems to have more treble but less body.

Hi @davida,

Thank you, I am lucky indeed.
I run them in class A for serious listening, and they use about 900W.

One thing I have noticed is that the P20 is always slightly below the target 230V, even when the system is in standby. Only by 0.2V or so, but it is still a bit strange.
Is that normal behavior, @jamesh ?

Guys thanks for replying…

My listening space is 15’ x 25’ x 8’ L shaped with a mildly vaulted ceiling.

My Focal 948s sit 8’ out from wall and about 3.5’ from side walls…my listening
point is 15’ from speakers with about 2’ left behind my listening point…speakers toed
in laser aimed at a point about 18" behind my listening point with slight 1 deg of tilt
back.

Results : crazy good imaging…

My 2 channel system:
Amp: Parasound A21
Preamp: Emotiva XSP1 Gen2

Power: P15 regenerator
Power cables: Pangea AC 9SE Mkii x2 Pangea AC 14SE MkII x 2
XLR IC: Nordost Red Dawn Oppo to EMO XSP1 Gen2 and from EMO to

Thanks again guys

.2V off from where you have the output set is within tolerance. Whether or not it’s actually off by .2V is a different story. The onboard oscilloscope isn’t lab grade, so it may very well be cranking out a solid 230V, but is reading it as .2V lower.

Being at exactly 230V hardly matters at all. What is WAY more important is keeping the voltage steady, specially through the big dynamic passages and when the input is all over the place. One of my favorite things about having PowerPlay back up and running is having the visualization of the incoming voltage being all over the place, and then the output being rock solid. It’s quite astonishing how well the PowerPlants regulate and keep the voltage steady.

Thank you @jamesh.
I found it strange because it was always below 230V.
I had a P5, and it had the same behavior, except that that the undershoot increased over time.
