XTZ Room Analyer
The XTZ Audio Analyser is a clever device that enables audio enthusiast to measure the acoustics of their listening room simply by connecting USB based hardware that will interface to most computers running Windows XP. As this review progresses it will become clear that the clever part of this product is not so much the hardware but the accompanying software. The hardware consists of a USB sound card module attached to a microphone on a flexible stalk. A heavy base is included that allows the USB sound module to operate remotely from the computer via its integrated extra long USB cable. In addition to recording sound, the USB module has an audio output that is connected to one of your amplifiers inputs. This connection allows the computer software to generate audio tones that are simultaneously transmitted and received by the USB sound module for analysis.
ACOUSTIC REVIVE
We have some intresting products to try from Acoustic Revive, we will have them on display in a highly treated listening room, they have some intresting products to say the least.
Principle/Structure
Highest grade silk without any side effect on sound quality
Chemical fiber is used in most of high-end room tuning materials surface
on market.
By using chemical fiber, it difficult to avoid side effect, such as
a peculiar sound.
Even if there are effects such as diffusion and sound absorbtion,
many usesr may have had the experience of having the feeling of the
sound becoming poor. This is because of the material used on the surface.
WS-1 uses only highest grade silk material from Hasegawa store, which
is the largest
silk wholesale dealer in Japan.
Silk in the only fiber that has random cellular tissue, so it does not have a outbreak of peculiar sound and an incidental sound.WS-1 give you extremely smooth and warm tone by the help of the superior diffusion effect.
Light weight and compact! Install it in any kind of place
WS-1 is easily installed onto the wall, because of it is extremely
light weight and compact.
Not to mention, on ceiling and small space such as back of rack mount.
On the back of WS-1, there is velcro tape. As soon as after purchase, it is easy to install on to the wall by using this velcro tape.
Flat frequency characteristic by special low repulsion urethane foam
Inside the WS-1, we adopted the special low repulsion urethane foam
for extremely fat sound absorbing characteristic across a wide range
of frequency.
Glass wool, carbon paper wool and polyester has an uneven sound absorbing
characteristic.
Instead, WS-1 has a very even sound absorbing characteristic. This
makes sound from the speaker very natural.

INFORMATION FROM ACOUSTIC REVIVE.
What is the Schumann Resonance?
The "Schumann Resonance" is a resonance frequency that exists
in the Earth's "electromagnetic" cavity; i.e. it exists
between terrestrial surface and ionosphere. German physicist W.O.Schumann
first detected the resonant properties of this terrestrial cavity
in 1954. It may be said that the Schumann Resonance is a breathing
phenomenon of the Earth that is lasting from old time. The lowest-frequency
?iand highest-intensity ?jmode of the Schumann Resonance is at a frequency
of approximately 7.83Hz.
Human and all animals and plants have been guarded by this frequency
of 7.83Hz and lived for long time. But recently, many unnatural radio
waves and electromagnetic waves disturb this frequency of 7.83Hz,
it have caused wrong influence on our human bodies.
We substantiate that there are many effects when the frequency of
7.83Hz is generated artificially.
Effects
For Audio equipments
By generating the Schumann Resonance, there is an effect that it neutralizes
electromagnetic waves generated from an audio equipment and external
harmful radio waves. So interference of electromagnetic waves and
radio waves that exist among equipments is disappeared, it becomes
possible to reproduce the music clearer, the S/N ratio is improved
higher and the distortion is reduced.
For Listening room
Also, by generating the Schumann Resonance, there is an effect that
it neutralizes harmful standing waves. And it has the feature of improving
the viscosity of the air in the listening room. Therefore, you can
reproduce the excellent music, the sound is improved clearly audible,
and the depth of the sound image is increased dramatically.
The
Acoustic Revive RGC-24 Ground Conditioner is an amazing new award
winning product from Japan... which dramatically lowers the noise
floor of the component it is plugged into... even if you already have
power conditioners and/or high quality grounding schemes (including
dedicated earth grounds). The super low noise floor achieved is quite
impressive... and provides greatly improved resolution... inner detail...
clarity... and an expansive holographic soundstage... all against
a jet black background.
Acoustic Revive RGC-24
Principle & Structure
Each equipments vacant digital input and analog input terminal are place where dust gets easily collected. Not only that becomes an origin of mixture for noise.
By letting these input terminal short-circuit, it prevents noise getting inside the equipment. Furthermore, letting the input terminals short-circuit, unstable element of electrical current on ground side gets removed and movement of machinery circuit becomes stable. Result is, advantage for power supply impedance and sound quality improves greatly.
In addition, board for terminal part tends to be very thin. This receives the influence of vibration. By using high specific gravity and hard material for short pin, it reinforces terminals and protects from vibration.
The best tweek and accessories we have is Stillpoints. What makes the Stillpoint system unique is the fact that unlike spikes, cones or ball bearings Stillpoints do not "tune" or try to "ground" vibrations in the vertical and horizontal planes, they absorb them. Decoupling is what sets them apart. As far as what they do for the sound of your system, they will open up the soundstage and reduce bass bloat when properly implemented.
The System consists of two parts: The Stillpoint and Riser.
The Stillpoint consists of an outer case (called the calyx due to its flower like petals that line the inner shell), two layERS of ceramic balls, and a stainless steel pedestal. The Riser is an aluminum base with a stainless steel stud, which accepts the Stillpoint. The System functions as a shock absorber for vibrations and resonances. The System changes vertical vibration into horizontal motion and absorbs it.
Following the path of vibration from the top of the exposed ceramic ball, as the component is placed on the Stillpoint, the vibration contacts the ball (at 12 o'clock) and proceeds down through the ball. Vibration exits that ball at the contact point of the second tier of balls at a diagonal (4 or 7 o'clock). The weight of the component expands the second tier of balls, forcing them into the petals. The petals flex and counter the vibration, thereby absorbing it.
From a platform or shelf, vibration enters the bottom outer rim of
the Riser, travels to the center of the Riser, and transverses up
the stud into the center of the pedestal. Finally, vibration travels
across the pedestal to the outer edge into the ball/petal mechanism
and is absorbed.
Stillpoints have another fantastic products called ERS . Just what is ERS and what does it do?
"...Immediately the sound was fresher, purer, and seemingly unencumbered
by digital artifacts..."
- Clark Johnsen, Positive Feedback
Stillpoints ERS redirects, absorbs, and diffuses EMI/RFI frequencies. The benefits of ERS for audio/video are best heard with digital circuits due to the RFI creating aspect of the circuitry itself. Benefits of ERS can also be heard with AC power lines, signal cables, loudspeakERS , and electronics of all types. However, in some analog circuits, the presence of EMI/RFI was tuned into the frequency response of the device. ERS can effect of the amplitude of the high frequency and/or the low frequency extremes resulting in a less than desirable balance.
"...ERS has to rate right up there with the HAL-O tube dampERS and the None-Felt turntable mat, as among the highest values in high-end audio..." - Rick Becker, Enjoythemusic.com
What's it made of?
The core of ERS is made of a blend of carbon fibers of various lengths
and sizes. Using a proprietary method, these fibers are coated with
metals, such as nickel. These fibers absorb, reflect and diffuse RFI/EMI.
ERS has on average about 66 db noise reduction in it's 10meg to 17
gig range. this is all that we can claim, due to it's defense restrictions.
The exterior is laminated with a polyester textile on both sides to
make the material easier to handle and use.
ERS may all be purchased with a pressure sensitive adhesive already
applied for easy and quick installation.
The edges of ERS do have exposed conductive fibERS and should be handled
and installed with care. The electrical resistance of ERS is .026
ohms per square yard.
The polyester fabric will insulate the core of ERS , to some degree,
but can be easily penetrated with sharp edges. Caution should be exercised
when used in close proximity to circuitry.
ERS is treated to accept many laminating resins such as epoxy and
polyester resins.

Why is it necessary?
With the exception of high end cables, EMI/RFI shielding is rarely,
if ever a consideration when designing audio components. Yet it is
one of the biggest culprits when it comes to sonic background noise
and "edginess" exhibited by some audio gear. ManufacturERS want to control costs, and adequate EMI/RFI control is not high on
the list of priorities.
With the availability of ERS , one is now able to address this problem
in their own system in a cost effective manner. Also noteworthy is
the fact that since ERS does not operate under the same principles
as a shield, it does not require grounding.
Useful Applications
The amount of ERS used is component dependent and must be experimented with. We have noticed that 100% coverage not necessary. Fine tuning may result in very little material required.
Listed below are just a few ways in which ERS paper has been used
to control and absorb EMI/RFI.
• In general, lining the inside of a component's top cover is
a good place to start. If you don't want to open up your piece of
equipment, then just lay the sheet on top.
• CD/DVD playERS - attached to the underside of the top, and
attached to the bottom. This covERS the power supply, and the digital
ICs. Digital is probably the most notorious EMI/RFI polluter in a
system.
• Preamp/ processors - attached in a similar manner as the CD/DVD
player.
• Home theater processors - Treat similarly to the DVD/CD player.
• Electrical outlets - Cut in the same shape as the wall plate
and place over the outside of the wall plate. The ERS is placed on
the outside of the wall plate because it IS conductive.
• Power conditionERS - wrapped around power cords, and covering
the top, bottom and sides of a power conditioner. A very effective
tweak.
• Power cords - Wrapping the cord with ERS tape. We have had
excellent results doing this. 1" tape works well. Multiple layERS work well too.
• Power transformERS - Keeps stray rfi and magnetic fields from
interfering with the audio signal.
• CrossovERS - Covering the top bottom and sides, as well as
wrapping the internal wires. This method needs to be "tuned"
to each individual system. You will know when you've added too much
ERS , when the highs start rolling off, or midrange detail starts disappearing.
Be prepared to spend some time on this.
• Interconnects - Wrapping the interconnect with ERS tape. This
too will require some fine tuning. I use a 1/4" strip wrapped
around the very end of the RCA connector's outer shell. You may also
try spacing the ERS away from the cable via foam pipe insulation.
• Loudspeaker cables - Fine tuning required here as well. Start
at the end that connects to the loudspeaker. You may also try spacing
the ERS away from the cable via foam pipe insulation.
• Video Cables - Component, composite, coaxial, and S-vhs cables
all benefit. Wrapping the entire cable provides the most benefit in
this case
How much do I need?
Hitting the level of diminishing returns with ERS is difficult,
and system dependant. Below are some minimum guidleines for using
ERS .
• Great results have been achieved by using the ERS tape to
wrap power cords and interconnects. If you are odering 1" tape,
generally you will need TWICE the length of whatever cord, interconnect,
etc. you are trying to wrap. An alternative to wrapping is to lay
the ERS length wise down the cord. This may take two, overlapping
runs to completely cover the cable, but it is a time saver. ALWAYS
do a "test wrap" before removing the adhesive backing!
• For lining the top cover of a component, a minimum of two
sheets are generally needed.
• For an amplifier, be sure to cover the area above and below
the power transformer at the minimum. It takes about 1 sheet to do so.

AURIC ILLUMINATOR
Optical Disc
Playback Resolution Enhancement
For CD, DVD, SACD & Laserdisc
Auric Illuminator improves the audible and visible playback quality
of all optical discs. Developed as an advanced optical resolution
enhancement, Auric Illuminator is incredibly effective.
Auric Illuminator will help your disc player to retrieve all the available data on your discs at the right time. Auric Illuminator allows the laser pickup to track the disc more accurately. It also improves discrimination of the exact beginning and end of the reflective and non-reflective areas on the track.
You haven't really experienced the true potential of digital formats until you see and hear the results of one treatment on a CD, DVD, Laserdisc or SACD. The subjective experience is greatly enhanced by Auric Illuminator.
The application of Auric Illuminator is an easy, two-step process. The application is semi-permanent. It should not have to be treated again unless the disc is cleaned with water surfactant or isopropyl alcohol.
The first step reduces ambient light and infrared light in the disc material. The Auric Illuminator light absorbing pen is used to blacken the inside and outside edges of the CD. (The outside rim and the inside of the center hole). This improves the signal to noise ratio of the reflected signal allowing for more accurate timing of the retrieved data.
The second step involves the application of Auric Illuminator gel. This unique product improves the optics by allowing laser light to enter and leave the disc with less reflection or scattering. This allows the pickup to "see" a stronger more sharply defined signal resulting in fewer data retrieval errors.
Auric Illuminator gel also lowers the disc surface electrical charge. The surface of an untreated disc will build up a static charge while spinning against the air. The static charge builds up until the voltage becomes quite high and then discharges into the air or surrounding surfaces. The charge/discharge cycle causes the disc to microscopically tilt or wobble. A wobbling disc is much more difficult to track accurately causing audible timing errors or even lost data. Although redundant codes can replace most of the missing data, the disruption of timing accuracy causes these errors to become audible. Buffering or re-clocking the data cannot totally correct timing errors or jitter. A vibrating disc is difficult to track accurately. This causes the pickup's servomotors to work much harder at maintaining focus. When the servomotors are constantly correcting the laser's position the power supply is pulsed more frequently. This causes excessive power supply fluctuations which affect the analog audio/video power supplies, degrading the overall system performance. By not allowing excessive static charge to build up, discs spin with less wobble making them easier to track. auric illuminator allows music to be more natural sounding and pictures to be reproduced more accurately.
Summary
Improves the optical signal to noise ratio by reducing ambient light in the disc material. This minimizes ambiguous signal transition points (reflect/non-reflect junctions).
Improves optical transparency by reducing reflection and refraction.
Removes stored energy from the disc surface and prevents future static
build up. This eliminates charge induced wobble making the disc easier
to track.
For just 45 €uros it will treat over 200 discs!!!
