Power Conditioners


I have about $5,000 invested in  a 2 channel stereo setup. Marantz PM7000N integrated receiver, Canton Chrono SL596 speakers, Rega P6 table, blue jeans Canare 4S11 cables. Is it worth it to buy a cheap power conditioner/protector like this  https://www.musicdirect.com/power/furman-pst-8-d-digital-power-station or this  https://upscaleaudio.com/collections/power-conditioners/products/pangea-quattro-power-center

Will I be able to hear a difference/is my equipment sensitive enough to notice a difference; or will a typical surge protector suffice? Otherwise, will it be a waste of money to spend money on a low priced conditioner?

Thanks!

Being an electronics technician, my recommendation would be the Furman, will get the RF.


Hey there, @pcrhkr - Furman makes different grades of similar gear. The Furman models which I recommend have LiFT and SMP, which are effective down to 3 kHz.  The series mode suppression is among the best there is.

If you have only looked at their less expensive line, your comment above makes sense.

Best,

You just gotta experiment, Erik your recommendation of the Furmans Lift and SMP I tried , I bought two of them one for a modem and switch ect on a separate Ac line and I tried the other one on my tv and digital cable box ect .
I then tried it my digital front end components for a few days and didn’t really notice any appreciable difference in the noise floor overall transparency. The digital video feed to my tv is excellent though with the Furman conditioner it was very difficult to actually see any difference in clarity ,contrast ,  color and what have you .

Sure on a budget and keeping your components safe I guess they would be great for the piece of mind however in my home they really did nothing though the Synergistic conditioner and power cords I tried did make a immediate difference with my tv and playback with my digital front end components though at many times the cost of the Furman conditioners and I still use the Furman on my modem ect for now .

SO WHAT EXACTLY WAS DEEMED INAPPROPRIATE  ABOUT MY POST THAT WAS REMOVED BY THE DESIGNATED MODERATOR? SEEMS LIKE OVER - REACHING FOLLOWED BY A LAZY ATTEMPT OF A  BLANKETED EXPLANATION, WHICH IS TO SAY IN THIS CASE NO EXPLANATION!

iFi AC iPurifier is $100 each and work very well. I would start with 1 or 2 of those. Highly recommended.
I’ll give another plug for the Audioquest powerquest.  I just bought a powerquest 3 on sale for my parents system.  They have some Focal Aria 926.  We all felt like the sound improved after we plugged all their gear into it.  Especially in the low end.  It seemed fuller.  It’s tough to quantify.  And I do worry about confirmation bias.  But you get peace of mind, and a warranty to boot from Audioquest.  And you don’t have to shell out more $ for another plug since the unit comes with one.  What’s not to like?  
I got Richard Gray 400 pro in my main system and Audioquest Powerquest 3 amp in my secondary system and very happy with both
Here's the most brilliant bit of marketing I've ever read, from the Pangea page, listed by the OP:

There are zero current-limiting circuits or electronic components of any kind inside."

The Furman conditioners with LiFT and SMP have lots of components which protect you against surge and also reduce noise starting at around 3 kHz.

If you want a "straight wire" with nothing changed, may I suggest the much cheaper kit from Parts Connexion:

https://www.partsconnexion.com/connex-kits.html

Personally, for $200 I'd rather have a Furman PST-8 which actually protects the equipment and reduced audible noise than a fancy box for power outlets, but that's just me.

Consider spending the money running a dedicated spur to your HiFi and everything connected to it, TV, PC, whatever, get it all isolated from the rest of the houses wiring. Far more bang for your buck. I also use a pair of Weiduka AC8.8's, very good value for money and much better than the Monster units they replaced.
Protecting your stuff against any electrical enomalies should be everyone’s priorities if you ever had to deal with a claim with your insurance provider, sometimes you are not in good hands . If your not sure how well your stuff would be protected during a lightning storm plain common sense should tell you just unplug it .

If a power strip gives you piece of mind great however like Atmosphere said power strips are not conditioners . Using conditioners , re-generation and transformer based over the past 30 years I’ve been disappointed with many manufacturers claims and enthusiastic reviews however I finally learned none of these devices are going to work as advertised for everyone.

Just recently I tried out , “home trial“ the conditioner and Ac cords from Synergistic Research they worked at dropping the noise floor noticeably well and as a added bonus they provide a decent quality power cord with their line of conditioners . My previous Inakustic 3500 conditioner and Inakustic power cords we’re replaced by SR conditioner.

follow me Ok? How much is your equipment worth?

+ 1, they are not for sound, they are for protection. The better sound is a byproduct of a cleaned up AC supply. Kinda goes hand in hand.. If it’s pretty clean to begin with, it might be hard to tell the difference..

Plug everything into cleaners, maintainers, conditioners, Tripp Lite is perfect, with a noise fix I have. Very quiet, NOW...

My issue is "try this, it sound better", WHY? What the heck did they leave out? LOL I want the protection.

Regards

My limited experience has revealed that surge protection limits dynamics and soundstage size. Two units that I've tried are the Brick Wall and Tripp Lite brands and both negatively affected the dynamics and soundstage. Others here have praised them, leading me to believe either they can't hear all that well or their systems aren't that resolving.

Even a Blue Circle Thingee without surge protection didn't sound as well as going directly into the wall. I barely heard a difference with my Marantz Reference integrated but it was plain as day with my Kinki Studio integrated.

It was when I tried the High Fidelity MC-0.5 that I got some taming of the AC nasties. Two more of them further improved the sound. But, it was when I got the Audioquest Niagara 1200 that I finally realized the potential of my system.

Nothing negative, everything positive, to say about it. The noise floor was so lowered that dynamics were naturally increased. Sound stage widened just a bit more (I've always had good results with that) but the depth and layering were greatly improved, again, from that lowered noise floor.

Tone, timbre and life like recreations are the norm now, as are frequency extension in both directions. Everything sounds just so much more authentic, completing the illusion, which is all it really is, but that is the point of all of this, right? 😀

All the best,
Nonoise
I have installed dedicated circuits in my current house and in another previous home in the Midwest. In each case they made a difference my non -audiophile wife could hear.

However, I am now using a lead -acid battery generator and it is much better. It generates a perfect 60hz sine wave. The model i use is a Goal Zero Yeti1250. I would have preferred one of their lithium -ion generators because they are so much lighter.

Based on this experience I should have saved the $$$ and just gone with the regenerator.
Knowing this is an older thread l’ll still make a late suggestion even though you may have made a purchase already. The inexpensive but good WAudio AC Power Purifier is very effective. I would recommend only for use with front end gear (DAC, CD Player, maybe turntable) - not an amp. I use mine with my DAC. Also, Amazon allows 30 day returns and I think the device is a great value.  https://www.amazon.com/gp/product/B00XWL2VVK/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
@foster_9  Thanks for the suggestion. I'll save it for future reference. Much appreciated.
Use the cheap ones for cell phone chargers, and the better constructed ones for your audio components. Make sure you run them in for a full day or so with a fan, TV or other appliance, then do several listening tests. The power conditioner may sound good with some components but not others. Verify for yourself. You may very well end up with one brand for the source components and another for the amps or subwoofer. 
If you use a surge suppressor, plug that in closest to the breaker panel, if possible.
I’m surprised in this thread and some others no mention is made of Sola ferroresonant transformers. 

https://solahevidutysales.com/mcr_portable_series_power_conditioner.htm

They’re not sexy looking, they’re heavy, they buzz, they naturally run hot, they’re not cheap and they’re hard to find (mostly because they’re made to order).

In spite of their drawbacks, not many other AC line conditioners do as much with so few components as a Sola.  No semiconductors of any kind.  No sacrificial MOV either, no need.

And yeah, I’ve used a MCR series for years and would not consider anything else.  And yeah, it lives in another room where I can’t hear it buzz.
I’m surprised in this thread and some others no mention is made of Sola ferroresonant transformers.
I don't see why- ferroresonant transformers make a fair bit of noise in their output, which should be a sine wave for best results. They are good at line voltage regulation, but otherwise make for a lot more noise on the line than the line would usually otherwise have.
“I don't see why- ferroresonant transformers make a fair bit of noise in their output...”


Noise attenuation
  • 120 dB common mode
  • 60 dB transverse mod
Is that a lot of noise on the output? 
Yes, because the waveform is not sinusoidal. So a lot of higher harmonics will be present that are rarely on the AC line. Electronics tend to be fairly sensitive to the 5th harmonic (300Hz in the US) which is much greater when a ferro-resonant device is used, unless there is a filter to remove the harmonics and thus restore the output to a sine wave.
atmasphere- 
Your point about non-sinusoid output waveform and generated secondary harmonics are well taken.

However, Sola mitigated this by adding an additional “neutralizer” winding in the secondary.  The following document contains a description of how it works.  Refer to the PDF page 4 under the heading “Ferroresonant power conditioners and harmonics”.

@puffball08 Nice! Sola has managed a nice improvement on where they were with this 20 years ago! 3% THD seems to be the number; A good power conditioner should be able to do about 0.5% THD (Elgar was getting this with their conditioners 35-40 years ago).


I tried using a ferro-resonant device made by Sola about 17 years ago in a power supply that featured AC line regulation- the noise out of the transformer was so profound that some of the circuitry in the amplifier developed oscillations. It would be interesting to revisit this and see if a conditioner with a device like this would be practical.

@atmasphere,

You may find this interesting.  This is Joseph Sola’s original patent from 1938 for a constant potential transformer, the forerunner of what Sola makes today.
