Is electrical interference a controversial subject?

In my case, no it actually makes sense to me on many levels. I am not an electrical engineer, scientist or the like, but I do like the hobby of learning and squeezing out more performance. I am from the mindset there is a lot of good gear out there, and it’s performance can be accelerated by focusing on the areas of power, room and isolation, versus the self-reasoning that better sound has to come from different equipment which opens up the door of, “is it better, or is it different”.

This game of noise is all about clean, quiet power drawn into our gear in order for high fidelity to sing its tune to draw you deeper into your favorite music.

Interestingly enough at the recent RMAF, I came across Bill Stierhout, and his company Coherence Systems, and its brand, ADD-Powr that signifies algorithm digital defined power.

As he was speaking about his new line of products, I mentioned that his theory and application sounded very similar to the Nordost QRT line, he told me it does because he was the founder of Quantum Products, the same company that incorporated its engineering prowess into the audio cable company, Nordost. While there is little to no doubt at RMAF 2019 all the top rooms had one common denominator, Nordost; using its cables and the QRT line. While I’m passionate about Nordost, it’s stupid expensive for most Audiophiles, well past diminishing returns, but I couldn’t help myself, drank the Kool Aid purchasing much of its Reference and QRT products, in my case it does perform, and very well, but anyway…

Bill agreed to send me a Symphony Pro, an ElectraClear and a guarantee his devices will work or I could send it back, no questions asked. You can certainly go higher up the food chain within his line, but I thought these two pieces would be good place to start as I wanted to be sure on what these items were capable of. Sorry for the picture quality:

First, there is no audio jewelry here, these are simply constructed units packed with benefits to improve the sound using frequency generators, harmonics and microprocessors that manage algorithms. Electra Clear is a simple plug in device that actually adds harmonics (pulsed/clocked signals) to the audio signal, a tone control through the power line if you will. There is no filter or conditioner, the byproduct of this process is that it also contributes to mitigating EMI and RF signals.

Symphony Pro is a small box that can be placed just about anywhere and is fed with AC power and houses inductor coils connected in series to a frequency generator controlled by a microprocessor performing algorithms that essentially pulses low frequency harmonic content onto the line, similar but slightly different to Electra Clear. The AC line becomes re-referenced / re-biased with low frequency harmonics. The inductor coils act as antennas to emit and broadcast a low frequency electrical field. The signal is also coupled to a 12’ plug in antenna wire. The driving low frequency wave and its Fourier harmonics resonate with the audio signals within proximity (~30' diameter) of its location. This means that tonal energy will be imparted to whatever audio signals are encompassed by this field.

Bill said it will bring .5 to 1.O dB or more of energy into the system - he was right; by flicking Symphony Pros small toggle power switch on and off and waiting a few seconds, it was very clear to hear the volume change, its literally controlling the noise making the music more audible, lively and toe tapping enjoyable. While volume was gained from removing noise and interference, it also brought about a sense of realism with a more natural sense of timbre, a lower noise floor, and a double black back round. The music just played so much better, no matter what I played. One of my favorites is Stairway to Heaven by Rodrigo and Gabriela; the resonance and decay of the acoustic strings and blending of the chords never sounded better. When I play Flight of the Cosmic Hippo by Bela Fleck a great song to test your low end has more authority and control and the symbols more in line on how they should sound live and the Symphony and Electra complimented the Beatles 50th anniversary release of Abbey Road making it simply sound amazing, especially the studio cuts; the band is center imaged, the music has a slight amount more of punch, liveliness with the Fab Four’s voices having very clear imaging and darkness, my music room appears to be the new Abbey Studios right in front of me.

While not inexpensive, but well worth the price of admission in comparison to all I have done, it’s a no brainer. The Symphony Pro lists for $750.00, and the Electra for $75.00 with options of moving up the line in performance, coverage and cost.

Last, I believe in power cables, and Bill holds this opinion as well and said it wouldn’t hurt but stopped there. While not mandatory, I couldn’t help myself after all the recent talk of Shunyata’s new lines and ordered the economical Venom 14, C5 cable, and after a few hours of listening, it’s not coming out.

Bill no doubt understands power and I believe his efforts with ADD-Powr have paid off—at least in terms of the product itself. How audiophiles will react is something I can't predict but I think many will react as I did and come to see these are an indispensable addition to their hi-fi systems. It has certainly change how I now listen to my system and they are not going back. If it makes sense, then give it a try, you have nothing to lose and add some cumulative points to your sound.

Thanks Ed. Nice write up. I better understand whats going now. Didn't quite get it on our phone call last week. I'm curious, are you paralleling the ADDpower with the Nordost QRT products. Dare I ask if you played them head to head. Do they differ in what they do?

I appreciate the thanks, writing does not come easy at least for me.

Yes AP is now in conjunction with my existing Nordost, and yes I started by playing them separately with the same benefits described above and it increases further when used cumulatively.

In terms of application difference, yes, but in the sense of advancement of technology.

You’ll hear it when you come here, and then we try it in your setting.

The best way to deal with electrical interference problems is by following 'good engineering practices'.
Experts like Keith Armstrong, Henry Ott, Jim Brown, Bill Whitlock (and others) have many books and papers on how to deal with the many different EMI/RFI problems.
 
Speed, I have not looked up the guys you mentioned but the papers I have read talk about good grounding, twisting cable or shielding to reject noise. Most like ballanced systems.

What few talk about is parallel noise canceling like a Bose headphone. If that is what the ADDPower does, that may be a new twist. Pollution on the grid is a growing problem. I dislike the plug into solutions. I hear them all in ways "I" dislike. I do have an Akiko Corelli. It's a dumb parallel device. I am interested in a smart parallel device. I can see how it differs from other solutions out there.
 
Hey Ed, do you know if the ADDpower senses the line and sends out canceling signals.

I know it sends out a signal, but need to look up the sensing part, will do some research.

There’s no intent to sense or control the line. It’s the pulsing signal with harmonic overtones that ride on the line and then onto the dc power supply.

Ed (Ultrafast) came over today. He brought some god awful expensive stillpoints and the ADD-power Symphony conditioner and Electraclear. The ADD-power products had a subtle, yet dramatic impact on playback. WHAT?????
Ok,
Subtle - I really did not hear much change. It was a touch more clear. A tad more immediacy. It was just more clean and clear. But, it wast like something stood out and grabbed you.

Dramatic - Ed likes to listen pretty loud. I usually listen at subtle levels but every once in a while I want to kick it up. Problem for me is it gets a little fatiguing at higher volumes for me. Enter the ADD-power. We got onto the new Beatles and playes and played Come Together a bunch of times. Each time we added the 2 ADD-power products in and out. Each time I was hearing the boost in clarity and dynamics. It was all for the good. Then we put on Stevie Ray Vaughan - Tin Pan Alley. This song begs to be turned up and that we did. I and Ed were pretty blown away at how good my setup was sounding. I mean, it was really laying it down. Clean, clear, effortless, and easy to listen too. By far best it's ever sounded, then I unplugged the ADD-power parts. Immediately I cringed. No way. Too loud. Kind of a cant put your finger on the problem but it had to be turned down. My stereo as stock just does not play at the volumes we were at. I plugged the units back in and immediately it was as above. Rock solid on top of the music. Just laying it down.

No lie, I pulled out $450 and said I want them. It took a few tries to get him to part with his new toys. He just got these pieces today. Heck, its a second set of the entry level products he was going to put on his router and modem. I convinced him I needed them more on my main system. Thanks Ed.

I highly recommend even the basic setup I bought. It makes a dramatic difference when you want it to, and a nice subtle cleanse at low levels. There is absolutely no negative impact to these devices. You don't hear them like ordinary plug in power conditioners. Technically they're not power conditioners. They don't get rid of hum and noise, but they sure do bring something that let's you open it up and rip the tunes.

All True!

The Stillpoint's we used were the uber expensive Ultra 6’s. We placed these under the First Sound Pre-Amp and then moved them to the Mojo Audio DAC then on to the Mojo Server - the largest gain was on the Pre-Amp. Then we coupled the Stillpoints with a more economical approach using ADD-POWR’s Symphony and Electra Clear. This really cleaned up things in a natural way making things more present and open with a better timbre around instruments, the effect was cumulative with and without the Stillpoints.

While Rex stripped me of my ADD POWR (I only let him since I already have several units of Symphony and Symphony Prop plus Electra Clears at home) he was not going to get my Ultra 6’s even at retail!

Glad we had some fun in Audio Land!
 
ADD-POWR continues to really be a benefit in the music room and the home itself.

Great places to start;

-Symphony
-Symphony Pro
-Electra Clear
-Wizard

Music sounds so much livelier and natural and the images on my older Pioneer Elite Plasmas are more crisp and colorful, amazing to watch College and NFL football on.

Any unit simply plugs into an open receptacle then the magic starts.

PM me with questions or interest in acquisition, I’m putting effort into this because I believe it’s that good!

I picked up ElectrClear this week and added it to my AQ1000 that I use for my streaming equipment. I have to say that the energy level of music just jumped up a notch. Today I ordered a Symphony that I will use on my other AQ1000 that is used on my Preamp/Lumin T2 and Oppo 205. To me this is a very affordable upgrade. Thanks Ed for posting.

King Rex is running exactly what you have, it will be of benefit, watch and enjoy!

Juat a reminder, it can be used with other power conditioners. But not with regenerators.
Glad your enjoying it. I have 2 electraclear and 1 symphony. The extra electraclear is in my basement with my router, modem switch.
