Power conditioner types

I know PS Audio (I believe) offered power regenerators.  Very large heavy units.  I tried a unit several years ago, no longer in production and it was nice.  However, my current power conditioner made my system sound better.  I'm sure the current PS Audio units are much better now.

Again, most utilities provide voltage that fluctuates depending on what loads come on and off on the system.  (before anyone argues with me, I am, along with my analog/digital Engineering degrees and background, a state certified Power Engineer working for a local utility).  So, for example, with stable loading, the system provides 120 Volts at 60 cycles per second.  Now turn on large loads/motors, etc.  That voltage will drop for a very short time until the system generation can catch up.  Same is true with frequency.  If large loads suddenly go away, the voltage may increase along with the frequency. 

This happens on the system all day at all hours.   more stable at late hours.  reliable utilities have generation on stand by and rolling to provide this much needed system stability.  So, even if a large generator is tripped off-line due to a fault, the system will remain relatively stable because of the other generation.

If you don't have a speed controller on your turn table, or if it isn't integral with your turn table, if you place a stroboscope on the turn table with a regular incandescent light, you can see if the speed is accurate.  depending on the time of day and system loading, it is not.  Hence the need for a speed controller.

But, there can be lots of noise on the power lines, which will make their way into your audio system.  Most equipment's power supplies have within the power supply filtering that will try to remove noise.  One thing power conditioners will help with is lowering the noise floor significantly.

To see if it is needed, it is simply a matter of getting your hands on some decent power conditioners and doing an A/B comparison.  With power conditioning and without it.  Or compare various conditioners.  

I can't speak for the really expensive heavy duty power conditioners that provide for large amps to be plugged in also.  Most choke the power to the point where amps don't sound good plugged into a conditioner.  However, as I mentioned, there are some that work quite well that allow for power amps to be plugged into them also.  They are really expensive, large and heavy.  But, they do work.

So, I can't say as some said earlier that power conditioners either work or don't .  It depends on what is going on with your system and the voltage from the utility.  is it clean and stable?  if not, then yes, you definitely need a conditioner.  

It is funny.  You think your system is great until you do an A/B in-home test with another piece and all of a sudden the background noise is way less or you hear things you never heard before in your music.  That is the problem.  There is always something better than what you have or something that can help.  

But, listen for your self.

Vibex Platinum. Made a significant improvement in a client's system with dedicated lines. If memory serves it is cheaper than much of its competition. 

@sokogear - 20 amp receptacle allows you to draw up to 20 amps if you have run 10 - 12 gauge wiring, probably on a 30 amp breaker.  Otherwise, use a 15 amp converter plug.  My system draws less than 2 amps when playing.  Existing 15 amp service is plenty.    

Hello,
I would recommend the Puritan PSM156 or the PSM136. You can now get a silver faceplate. This thing really makes a difference in the sound. It sounds like someone took off the cover off of your speakers that was blocking the sound. Plus, it help your whole system even if you plug your amp directly to the wall as long as the Puritan is on the same breaker by filtering out tons of hash or impurities. It does not store power like my old Monster 2000 used to do. I used to have a 20 and 15 amp Furman. The Puritan helps so much at producing perfect sound it’s not even a comparison. Plus, Most power conditioners have banks of four outlets. Every outlet on the Puritan PSM156 or 136 is discrete. All of the filtering with none of the restrictions. I bought mine at a dealer in the Chicagoland area called :

They let you try before you buy which I did. I tried it and bought it. I knew I could not live without it in my system. Plus it comes with a nice power cord unlike the AQ Niagara. You have to buy theirs. I hope this helped. 

Puritan PSM156 + 1

It has surge protection, DC removal, twin transformers to freely allow 20A current flow. Using two inductors to remove in process high frequency noise riding on the alternating current, it shunts to ground the noise from both the active (hot) and neutral (bonded to ground) back into the ground wire. An external ground can also be used, apparently with even better results, it has a slightly different potential if it’s not bonded at the panel, you will want to use the Puritan ground with that.

Shorting the high passed noise to ground is also the technology that German InAkustik uses. However, the Puritan has separate circuits isolating each outlet shunting noise to ground, so that switching power supplies (if you can swap them for linear it will yield better results - generally) won’t introduce noise into other devices plugged into it.

I did quite a lot of research before being tipped off on this little beauty. It may very well not be the best, but as far as I know, for the money, it’s a black horse that should be tried.

It has revealed a lot more information hidden by noise that my power supplies could absolutely not remove in rectification and using smoothing caps or the LT3045 in my power supply.

@mijostyn

You might need a hair conditioner or perhaps a surge protector but you already have a power conditioner. It is called a power supply.

Please explain to me where in the four way bridge rectifier, smoothing capacitors, or LT3045 it makes for perfect DC??

Anything else is a waste of money.

Unless it’s absolutely not a waste of money! Then it’s simply superior technology, that delivers a better result through impressive engineering.
But go ahead, and "know" that it’s snake oil, while those curious enough get the benefits.

I have by all reports read the Niagara range (and many even significantly more expensive conditioners) also are very good at noise removal, as are many others. Compare prices, features (an important one is surge protection another is removal of DC), and decide for yourself.
