Greater involvement in sound & vision
The SCHUMANN RESONANCE PLUG generates a new 7.83 Hz wave and counteracts the adverse effects of RFI & EMI radiation. Audibly, this results in a purer sound with a fuller timbre, more detail, a deeper soundstage, and more power and dynamics. The background is quieter than ever before. Video will appear sharper, with more contrast and richer, fuller colors. Greater engagement and a more realistic reproduction are the key features of the SR Plug. These improvements are difficult to capture in graphs or tables, but will be immediately clear to anyone with a decent set of eyes and ears.
Reviews:
Home Studio, mei 2008 “Even mysterieuze als muzikale accessoires” by John van Polen
“The SR, in fact, does very different things with the sound than the QA plug. Its effect lies more in the realm of clarity, attenuation, purity, and the complete flattening of noise. A cleaner, leaner, more analytical sound with more detail, without the image shrinking. After a few days of breaking in, the combined effect of both plugs seems to have increased even further. The sound has become more natural; it simply sounds more like real music.”
Quality Hifi, 2014 “Schumann Resonance Plug 2014 van Kemp Elektroniks” by John van Polen
“… a milestone in the field of accessories”

“More spacious, fuller, less sharp, more low level foundation, “more instruments”…”

“Something happens with the purchase of a Kemp plug. Something miraculous.”

“Highly effective, completely unique, and remarkably affordable accessories…”
Ron’s Audio Blog, November 2011 “Kemp Pluggen, klein maar fijn” by Marc van Berlo
“I experience it as an upgrade for the tweeter. The high frequencies, in particular, benefit from the resonator being engaged; in classical and jazz recordings, where individual instruments such as flute, violin, and bassoon are clearly distinguishable, it seems as if an extra ‘silver sheen’ becomes audible; notes sustain longer; very beautiful!”
Test “Tweak SR, SNS and QA Plug” by Kurt Lassen@Fidelity Magazine
“With such a price, it is almost impossible to live without it”
Kemp Electroniks Schumann Resonance Plug | “Resonates with me…” by Clement Perry@stereotimes.com
“The sonic benefits of adding the Kemp SR plug(s) to my listening room were immediately and clearly noticeable. Even with the RR-77 still switched on, I clearly heard greater three-dimensionality by placing a single Kemp SR plug right in the center between my Sunny speakers. Yes, all the praise previously attributed to the RR-77s applied to the SR plug as well. Instruments sounded more spacious and fuller. The acoustic space of each recording also came into its own better, making the feeling of being “transported to the recording” even more believable.”
“Kemp Electroniks SR Plug A Follow-up” by Dennis Parham@stereotimes.com
“Ultimately, placing two more Kemp SR Plugs on my front listening wall resulted in a wider soundstage with more three-dimensionality – and, not to mention, a sweeter and more refined sound. Dynamic nuances gained a greater bandwidth, while macro and micro details became increasingly audible. All in all, I must say that the sound became cleaner and therefore clearer, giving the music more freedom and producing a much more captivating sound for me.”

Herman from Chicago –
First impressions of this device are positive: if fact, very positive but difficult to describe. To sum up the very unusual effect would be to say that music played through my system sounds more “pleasant”. This is an ambiguous word but my wife confirmed this description. She mentioned that listening with the SR plug is “less strenuous on the ears, easier on the head”.
Some responses from one of our US dealers; Highend-electronics –
…I hooked it up last night. This thing is nothing short of amazing- it’s presence worked a great improvement in my system. The reviews of this device were right on the money: it may be the most cost-effective tweak I have ever used.
The music presentation is super clear, even more dynamic and soundstage depth and width presentation is so real. This is the most significant tweak in my 20 years into hifi. Simply breathtaking…
Dhr. van den Oever from Katwijk aan Zee, the Netherlands (translated by JvP) –
Yesterday, I collected a SR-Plug at my dealer’s to try it at home. I kept the device right away, because this Plug does exactly what is in the review by Mr. John van Polen. A lower noise floor, bass is more taut, more accurate imaging and better retrieval of detail are among its effects. In short, an astounding result.
Dhr. Wintels from Heerhugowaard, the Netherlands (translated by JvP) –
Being a gratified user of the Kemp QA-Plug and SNS-Plug for several years now, I was very curious about this new SR-Plug. It must be said: the effects are obvious at once. A more refined treble, better retrieval of detail (even new details appeared!) and a more “real” sound. At the start, I was too lazy to strech out the antenna, which was wrong, because this clearly enhances the effect. At my place, the SR-Plug sounded at its best when set at maximum output. This triggered the idea of buying another one, which raised the benefits as expected. In my opinion, this is the best Plug Kemp has ever made.
Ivan Benja from Milan, Italy –
I feel very happy with “my” sound: wide, deep, open, transparent, tidy, rich, dynamic. I can hardly imagine anything better downside a 5 figure high-end exotic monsters. At least – until this weekend.
*Step 1: turned potentiometer down to zero, plugged SR and here-we-go. I’ve chosen Hail-the I Dub compilation: a heavenly production, clean, clear and tidy.
*Step 2: turn clockwise to 9 o’clock. Apart slightly deeper bass (illusion?) I did not notice audible differences.
*Step 3: potentiometer turned to 11 o’clock. Wow! Bang! The bass got “edge”, the soundstage depth becomes deeper, higher, wider, naturally balanced with whole lotta “black space” between instruments. Almost holographic. Voices placed in front of drums (as it should be), colour and tidiness of voice to die for.
*Step 4: potentiometer turned from 1 o’clock to max. Too much of a good thing equals nogood.
*Back to 11 o’clock – back to heaven. The sound reminded me to the “deep listening” sessions after bong (ab)use when I was young(er).
*The last step: SR Plug switched of. The sound I’ve thought was fine. seemed – wall of sound! Plugged again. I will never unplug it again. I damn love it.

The music presentation is super clear, even more dynamic and soundstage depth and width presentation is so real. This is the most significant tweak in my 20 years into hifi. Simply breathtaking!
Khat from Japan –
When I plug the SR and placing the wire between my speakers, immediately everything become more cleaner with great hights making me to hear more from the recordings. Micro- details. Wow! what a great tweak.
P. Kolijn from Aalsmeer, the Netherlands (translated by JvP) –
If you ask me, the Schumann story was made up by Kemp altogether; however, strange enough, the thing actually works. All claims are fullfilled! How that can be, remains a mystery to me … .
Mr. Kong Wy Mun from Singapore –
Received the SR plug replacement yesterday and tried it last night. Must say that I’m happy with the results. 🙂 Imparts a more controlled feel to the sound and allows one to be better drawn / relax into the music….
Jeroen van het Hart from Hillegom, the Netherlands (translated by JvP) –
In our audio hobby group, we lively discuss and disagree on almost every audio product. Very rarely it happens that, so to speak, all noses point in one direction. But in case of the SR-Plug this rarity occured. Friend and foe agreed: This plug is one hell of a sound enhancer. The perceived effect was regarded as an enormous improvement unanimously.
A customer who wish to be anonymous (translated by JvP) –
Recently, I made a shocking discovery: both my QA- and SR-Plug are extremely sensitive to the quality of the mains! Using a high quality power strip is mandatory! I noticed that I was throwing away about half of the benifits of the Plugs when placed in a standard power strip. Fortunately, I managed to insert both Plugs into my dedicated audio power strip.
Gerard v/d Bergh from Bloemendaal, the Netherlands (translated by JvP) –
This weekend, my dealer gave me a SR-Plug to try at home. From the first moment on I was convinced of the enormous effect on my audio system: a more open / wider / deeper soundstage, a more detailed, tighter sound and better pace and rythm!
That evening I was struck by the picture of my Sony Trinitron CRT-television being more composed, focussed and detailed and displaying a much truer color balance also. I could never have expected to see this on my ten year old TV; in my opinion, the contribution of the SR-Plug here is even more prominent than in my audio system … !
Michael Bakker from Breda, the Netherlands (translated by JvP) –
Rather plain looking product that does an excellent job all the same. My description of the looks as “cheap”, should not retain anyone from buying, because it’s the result that matters. I had the honour to be able to compare it with the Acoustic Revive and, believe me, the SR-Plug performs many times better. On the basis of appearance I tend to prefer the Japanese design, but whether one should pay many times more for less performance … .
Fred van Ingen from Bergen aan Zee, the Netherlands (translated by JvP) –
My system from Van Medevoort always sounded somewhat harsh. There was just that ugly edge on the highs. After some fruitless experimentation with respect to cabling, it was at the Alkmaar show that I ran into Ron Kemp, who advised me to try his SR-Plug. Fortunately, I did. For an investment next to nothing, all harsh edges have disappeared and, as an unexpected bonus, the soundstage opened up completely. Much more spacious and realistic. This accessory is mandatory for every audio system in the serious league.
Robert Mastenbroek from Schipluiden, the Netherlands (translated by JvP) –
A set of Plugs from Kemp Elektroniks (SNS, QA en SR) managed to turn a mid-priced Panasonic system including a digital amplifier from “seldomly used”into “always on”, evoking goosebumps and even the occasional teardrop on a regular basis. What more can one wish for … .
A customer who prefers to be anonymous (translated by JvP) –
At first, nothing seems to happen at all. But about 7 minutes later, the music comes into bloom: more depth, better retrieval of detail, especially in the low and the high frequencies and a more “immediate” sound. When I unplug the SR-Plug, it takes about three minutes before I start missing something; when I put it back, it again takes about 7 minutes before I can say to myself: oh yes, that’s the sound, now it’s right again.
Frans Strik from Oldehoeve, the Netherlands (translated by JvP) –
The entire “sound image” gains quietness and I perceive new details between and behind musical instruments. Certain tracks from ‘The Maze’ from Sounds From The Ground sounded somewhat weird and diffuse; with the SR-Plug in place however, the whole thing comes together. In particular, the vertical image of musical instruments is defined much better. Also, the noise floor has dropped further. The power transmitted by the SR-Plug is adjustable, the result described above is achieved at half power output. In my system, maximum power output is way too much; the sound becomes rather “shouty”, reminiscent of a system playing in a large hollow space.
John van Polen from Leiden, the Netherlands (translated by JvP) –
Today, I transferred a SR-Plug from an ordinary power outlet to my MIT Z-Center power conditioner. This power line is also filtered by a Tice Line Enhancer and three PS Audio Noise Harvesters. This change resulted in a clearly audible improvement! A piano has a more natural timbre now and highs sound purer!
Matthias Diepenbrock from Berlin, Germany –
Unfortunatley, there is no dealer in Germany to sell Kemp products. However, the money back guarantee convinced me to buy them on the internet. I’m glad I did so, because the combination of SNS, SR and QA modules performs breathtaking in my home cinema system.
A customer from Denmark –
I took the plugs to a friend who has a very good HiEnd system. It was incredible how big the improvement was with only three or four plugs in all the corners and just one SR plug in between his speakers. He just couldn’t believe it, we sat down for maybe 3-4 hours and just listened. Great!
Our Singapore dealer Passion Audio –
We received the plugs and use a SR plug in one of our demo system. Wow, the effect is very audible, it help in creating a wider and deeper soundfield, vocal seem lusher and less gritty, the SR seem to have taken the tightness in tension on vocal, imbue it with warmth and retain the speed and tempo. Also the high seem more silky and extended. I am not exagerrating, it is true as we are very familar with our system. I hope you can quote me in your website.
F.H. from Germany –
To be true, when I ordered the sr-plug the first time, i thought that this could be a waste of money. I installed it in our dining room, to check if it works outside a music system. Our dining room is a room with lots of reverb, so that sometimes conversation could be stressful, especially when our kids scream and shout. Surprisingly situation changed, when I installed the sr-plug. Words are easier to understand and the noise floor isn’t disturbing any more.
After this unexpected effect, I ordered another sr-plug to use it in my hifi-system. I received the new model. And this on really knocks me off. After my experiences I did expect an improvement of the performance of my music system. But the improvement wasn’t slight, it was immense. More detail, more soundcolours, a relaxed swing… fantastic. I didn’t tried the old sr-plug in my music system, so I don’t know, if that one works as good, but in my opinion there is only few, that makes such a huge improve of the system for such a relatively small amount of money. If someone asks me, I would really recommend your plug.
