There Are More Things In Heaven And Earth...
...Than Are Dreamt Of In Your Philosophy.
Electrical, mechanical and magnetic phenomena do matter in audio. Some visitors of my pages certainly do remember the loudspeaker cable debate which started around 1978. The first experiments were done by a few freaks who would buy the thick cables used to connect car batteries, then isolate them and connect them between amplifier and loudspeaker cabinet, at best directly to the circuit board of the power amp and the loudspeaker filter, eliminating bananas, sockets and binding posts. They reported about the audible benefits. There were well known reviewers who laughingly wrote that the moon had to be in the right position to hear the differences, ridiculing the seriousness of those who have a deeper sensitivity. Today it is generally accepted that impedance, resistance, long crystals, dielectricum, bronze, copper, tellurium, rhodium, silver, mass, resonances, and what not, do matter.
Today only fools do not know that resonances occur in all sorts of materials and that grounding (as instructed by the designers of Goldmund) is of a blatant significance; that lead can be a disastrous material if used unwisely; that electrical currents have their effects; that electromagnetic fields generated by transformers do deteriorate the digital to analog conversion in a CD player; that... you just name it.
a step further is discussing the benefits and also the drawbacks
of certain AC Power Line Filters or specific Power Conditioners.
It is true,
a shiny design is very appealing. But fortunately there are also those
who do hear the intrinsic value of the various combinations of materials,
the composition of components, the topology on circuit boards, and the
way a specific component is constructed, be it an amplifier, a cable,
CRISP AND CLEAR
it is freezing cold and the air is dry, we noticed that the reproduction
gained in sharpness, firm detail and assertiveness. That is bullocks
to many. Roughly 85% of listeners content themselves with restricted
information and maintain that they do not hear the differences.
As said, this group includes a few reviewers as well. If they
are happy with it, happy they shall be, like that music lover
who wrote his "views on digital and analog" on the Bearac
Blog. But to the good hearing crowd it is a serious and acknowledged
Now your brain has the ability to filter out disturbances, distortions, disorder. Classical collectors of historical material can easily listen to the background noise of an old record. But they frown their eyebrows if the sound is not harmonic. The brain gives priority to the essence of the sound. Sensitivity of hearing has led to many experiments. We witnessed demonstrations of CDs being treated with a demagnetizer. It ruined the sound of the instruments and the orchestra. It took hours for the CD to be "normal" again.
In the early nineteen nineties the Audio Engineering Society (AES) held their meeting in the Netherlands, in the city of Leiden. A member demonstrated the effect of Tourmaline when placed on the binding posts of the loudspeaker system. Again the sound was more liquid, but also weaker, lost some of its harmonics. Although many in the audience said they could hear it and preferred the sound, my editor and I gave our firm opinion.
BEFORE AND AFTER
of these trials stem from the desire to make the sound reproduction
(especially from digital sources) better, to make it more
analogous. Specific materials can be used of course. But
the application should not be implemented afterwards, but
incorporated during the design stages. Silver cable can
be very good, but you have to design the loudspeaker systems
specifically while they are connected with silver cable
and determine the positions and relations between the units,
the shape of the baffle, the volume for proper loading,
the filter sections, etc. Chunks of tourmaline on the binding
posts? OK! But you have to put them right there from the
start when constructing the system.
WHAT IS YOUR REFERENCE
all depends what your personal reference is. Not long ago I spoke
to a visitor from Taiwan. He is an analog adept. I advised him to
attend a concert in the Concertgebouw. He told me that a few days
ago he already had witnessed the orchestra in the great hall on
two occasions. And he added: "One distinctly hears the Philips
sound." Indeed the Philips engineers used the hall for many
recordings, but they also knew to convey in their recordings the
spaciousness of it. Living in Amsterdam, the Concertgebouw is my
favorite sound reference, and then sitting in row six or ten preferably.
In any case not too far away from the orchestra. There you have
the left right experience, the impact of dynamics, etc. I once attended
a concert of the New York Philharmonic with Zubin Mehta in Lincoln
Center's Avery Fisher Hall and was rather disappointed about the
ADDING A NEW COMPONENT TO YOUR AUDIO SET
human being is susceptible to changes in his life. Following

When a friend sent me a link of a page featuring the Ultra Low-Frequency Pulse Generator RR-77 of Acoustic Revive and added the annotation: "I think these people are crazy", my curiosity was sparked. The immediate thought was: How can you presume insanity if you do not investigate?
IN TUNE WITH THE UNIVERSE?
The researchers and designers of Acoustic Revive let us walk into a complete new dimension. It is the knowledge of a basic phenomenon occurring in a much larger realm than our listening rooms. And it is the application of it to our music systems, if we want to. The phenomenon we are dealing with is the Schumann Resonance which occurs in the earth's cavity, the space in between the surface of the earth and the ionosphere, 55 Miles above it.
cavity has a very low fundamental electromagnetic frequency which is
brought about by the discharging between the positive ionosphere and
the negative surface of the earth. This discharge produces an extremely
low frequency (ELF). Although it was German scientist Winfried Otto
Schumann (May 20, 1888-September 22, 1974) who suspected, predicted,
and finally calculated that frequency (eventually with his students),
it was in fact Nikola Tesla (July 10, 1856 January 7,
1943) who discovered the discharge phenomenon. Enlightening in this
Earth Breathing, a comprehensive article about the phenomenon
which is an essential ingredient of biological life. Schumann calculated
that in the cavity an electromagnetic frequency occurs of round and
about 7.8 Hz.
Electromagnetic radiation is a form of energy. It has properties of both an electric and a magnetic wave and travels through a vacuum with the speed of light. The space between the surface of the earth and the ionosphere is not exactly a vacuum but comes close to it.
have found that the Schumann Resonance and the other resonances mentioned,
are an essential ingredient of life. It is a natural occurrence. This
electro magnetic field has always been there right from the moment when
the earth had settled. In theatrical terms one could say that it is not
just a prop but a basic part of the set. The resonance is said to be essential
to the proper functioning of the human brain. (It has an effect on the
Alpha waves produced in the brain.) However in industrial regions, in
large towns and big cities, this electro magnetic field is generally disturbed,
obstructed, is weak, or it may be missing and does not occur in one's
existence. This impairs the well being of every living creature in that
region, be it human, animal or plant. It is said that the absence of the
Schuman resonance could make you ill.
there is an effect of the Schumann Resonance on the human brain. The workings
of the RR-77 was easily established by listening to music, first with
the RR-77 switched off, and then with the generator switched on. The instruction
is that the RR-77 is to be placed at more than 1.50 m above the listening
room's floor. That was simple enough by extending a record shelf, just
enough to place the RR-77 on.
the question is: Does the Schumann Resonance have an effect on the working
of components as well? And to what extent?
Recording music with the RR-77 switched off and on.
I put a blank disc into the tray of the Tascam CD-RW900 and recorded the beginning of "Misty", the RR-77 not connected. Then I interrupted the recording and switched the RR-77 Generator on. Now I recorded the same passage. In both instances the music was not reproduced by the loudspeakers during recording. I did not use earphones.
In order to check if there is the slightest influence of the RR-77 Generator on components, I played back the two short recordings on a Denon CD player. The RR-77 switched off of course, in order to eliminate the slightest influence on my brain (if that influence was ever there and measurable). I also did not want to add any possible influence generated by the R-77 for a second time while the reproduction took place.
Playback. The RR-77 Generator switched off.
had experienced the difference when listening with and without the R77.
Now, what would I witness by only listening to the two recordings? If
there was any effect of the R-77 on components, these two recordings would
sound is more liquid, has a more stretched out high frequency content.
The frequency band seems to be larger, wider. Slightly more hiss was noted,
but that was caused by the two low budget two-way systems used for evaluation.
In high end loudspeaker systems this will not be noted. Again there was
no congestion, there was more airiness, more space.
recordings showed that the influence on electronic components was significant.
The Pulse Generator and the Tascam CD-recorder were about 4 meter apart.
Of course this distance is not important, has no value.
I cannot say that you should have the RR 77 incorporated in your home. But if you suspect that after reading this page, it may be beneficial, go to your dealer and ask if he can give you one Acoustic Revive RR-77 Pulse Generator on loan for a week end. That is the best way to find out and to decide. I have been living with the RR77 for over two months now and I will continue to subject myself to its workings (not only for my audio set but also for my well being I tend to think). I may even update this review in due time as I will give the RR-77 on loan to a few friends who are also very much into audio, one is a critic, another a manufacturer, and the third one is just a music lover. I will ask them to give their evaluation.
The Acoustic Revive RR-77 Generator is a very small component. It only measures 14 x 16 x 4 cm (W x D x H) and weighs 200 gr. The pictures on the right show the unit and its innards with the labyrinth and the small section with components. The power consumption is 2 Watt and the generator runs on 12 Volt DC.
