Power conditoner..


I have a stand by generator for my house. I've noticed when we have an outage & the generator kicks on the lights in the house are brighter.  They are getting a full 120v.  Because of this I thought a power regenerator would  make a big difference in my stereo.  I installed a PS Audio Stellar 3 Power Plant & I can't tell any difference.  Oh well, live & learn.

Your amp doesn't care much what voltage it gets so long as it is in the range.  Get a voltmeter, you may find your generator is putting out 130 volts.

but it is disappointing that you don't see any improvement from the PP.  Are you using heavy power cords (10 awg, at least 12) from the wall to the PP and from the PP to the amp?  

I use  PP10 with excellent results.

Gen is putting out 120v right on the $. I'm using a heavy cord from PS Audio.

 

I am new to this site and obviously its, Forum, however, carlsbad2 is correct.  Anyones amp does not care about the input voltages as long as they are within the stated range.  If you have "brown power" that is also an entirely different matter, and your problems are more serious than simply affecting your amp.  You can rent a voltage recorder and attach it to your incoming mains for a week, or, a month, atypical rental period.  This has to do with your area and your hydro supplier.  Your amp experience may be a "canary in a coal mine" indicator, and, it would be worth investigating.

I am not familiar with the PS Audio model you mention, and in no way discrediting your PS Audio purchase because I believe many of these devices are excellent in filtering the line. 

@fertguy the PP is programmable to put out whatever voltage you want.  Like I said, the voltage doesn't matter.  the quality of the sine wave is what does.  

If you are getting no improvement, the power supply in your amp (and other equipment) must be very good and manages the noise in the wall power.

What amp do you have?

@fertguy

Return it to PS Audio after discussing with them first. I know that power amps can draw a lot of current and that you must be careful to make sure that your power device is up to the task of delivering lots of current during musical peaks.

If the lights are brighter enough to notice, your mains voltage must be pretty low. Have you listened to stereo with generator on?

That is a good Approximation, BUT

An Amp can ONLY produce  a relative output within and given operating range. If you have say low power you can not get something from nothing, that isn't there to begin with and you will have a comparatively weaker output. If your Bias voltage is off or your output supply voltage is Low/High, your output will change along similar lines. The circuit can TRY to compensate but there is no circuit that can demand an output. Even a constant current amp has it's limitations.
On the other hand your statement about PP is right on and that is a great place to lock in some stability and consistency.

PS Audio PowerPlant, like everything else audio, is a YMMV thing.

"the PP is programmable to put out whatever voltage you want. "

The OP's model does not have that feature.

I have PS Audio M1200 mono-blocks. I haven't listened to the stereo with gen power on. Guess I need to try it.

I’m so pleased with the PP that I use 2 of them. I can hear the improvements with them. The larger one is used for my 300B monoblocks and tube preamp. I can similarly hear improvements with my Studer RTR. The smaller regenerator is for my paired subwoofers alone. The top model PP is highly programmable with variable caps. They work well for me in rural NC with our power concerns. My flea powered system is tuned for analog detail that likely impacts what I can distinguish.

After reading the comments & the way my voltage must be low, I may need to upgrade to the PP12 or 15.

 

@esarhaddon1 I don't mean 60V but 110 is fine and no place in the US has less than 110V now.  Indeed, a tube amp bias needs adjustment for different voltage.  That's why a power inverter like the PS audio is great for tube amps.  It does make it a little boring--never getting to touch the bias adjustment knob.  

Hope you're having a great audio sunday.

You betcha I'm having a great day and haven't even turned on the music yet! 
Also I was not trying to imply that the changes would be drastic, but just there.
Also I have seen numerous places where the voltage can change anywhere from just under 100v to 130v. I had to call the pub utils just about 6 mo. ago for that particular high voltage and I know of one apt building in Colorado Springs that was having a cascade failure of Air Conditioning units and when they put a voltage recorder on the line they found it was due to something as ridiculous as 95v. Of course I do live in this backwoods outpost known as Denver!

i don’t think you need to upgrade your unit. the main reason to upgrade would be your equipment needs exceed the power regenerator. You could double up the smaller unit ( like a mono block) and dedicate the equipment to each one. 

I have an Inakustic 3500P Power Conditioner for sale on US Audio mart.  I have decided to upgrade to the 4500P level to support a new system.  

What you are describing is called "switchover" transient - in essence, there are at least three factors in play: a) synchronization issues between the sinewave (or as close at it gets with the generator) waveform and that of your AC mains, b) ramp-up artifacts of the generator when it (or UPS) kicks in, and c) control circuit problems that governs the switchover.  The "steady state" performance of your power conditioner is of little importance here - its transient response is what matters.  This article from Repeater Builder provides good explanation: https://www.repeater-builder.com/backup-power/ups-test.html  Your regular surge protector will ignore such artifacts, and likely your typical power conditioner will do so as well.

Tooting my own horn, our filters https://www.onfilter.com/ac-emi-filters-af-series do deal with such artifacts - at the factories for which they were designed such glitches may cause very serious problems rather than just an inconvenience of flickering light or a crackle.

I have found my amps sound better plugged direct to the wall and not in my P10

You may have good power from the grid as it it. The whole house generator shouldn’t make any difference, I have a generac and when it kicks in there’s literally no difference. Count yourself lucky.

@esarhaddon1 

we have had similar issues in my area. It was discovered that some apartment complexes had individual certain families each occupying every room. Meaning five to six families living in a single unit. They would steal electricity by running extension cords to outside outlets of any property near by or from the complex it self. This would cause a drop in service that they could not account for until discovered. With 20 to 30 million more it’s going to get much worse. I know how bad things are in Denver as I attended a work conference there and can tell you I will never and I mean never go back. We had a three year contract and cancelled the two remaining years. Good luck and enjoy the music.
