Product Description
The DS Audio ES-001 allows you to enjoy better music without Eccentricity.
The overall wow and flutter of the entire system cannot be
significantly reduced unless the eccentricity of the record is corrected
With an eccentricity width value of 0.34mm, even if there is
no inherent wow and flutter (speed error) produced by the turntable in use, it
reaches around 0.15% (WTD RMS) on the innermost grooves of the records playing
surface. In reality, the average speed error value of even the highest quality
turntables is around 0.008%. These factors combined can result in an overall
wow and flutter value 20 times worse than that of the turntable in isolation.
Put simply, when using even the finest quality turntables available, the
overall wow and flutter of the entire system cannot be significantly reduced
unless the eccentricity of the record is corrected. In order to faithfully
reproduce the source material, it is imperative to reduce the record
eccentricity as much as possible.
Excessive wow and flutter presents two problems
The first is that the unstable rotation causes fluctuations
in pitch across the frequency range. The second is that if the record eccentricity
is not corrected, the cartridge and tonearm will be forced to sway from side to
side as they follow the groove. This impairs the stylus ability to accurately
track the groove and results in a muddy sound and an unstable sonic image.
As a result, the full potential of even the highest quality systems will not be
realized by the listener. Correcting this eccentricity as much as possible
allows you to unlock far more of the potential performance of your equipment.
DS Audio ES-001 Adjustment in 3 Steps
Measurement
When the record player is rotated, the upper part of the
stabilizer is held to stop the rotation of the stabilizer, and the stabilizer
detects the rotation and shifts to the measurement mode.
When switch to the measurement mode, the display on the outer circumference of
the stabilizer starts to rotate and the [Tap to start measure] button is
displayed.
Next, when you press the [Tap to start measure] button, the display changes to
the [Measuring] button and the measurement is completed in about 2 seconds.
Adjustment
Stop the record player when the measurement is complete.
Next, while looking at the stabilizer screen, press the record board to bring
the cross mark (center of rotation) as close as possible to the absolute center
position.
The degree of eccentricity of the record is indicated by the color of the
screen (outer circumference, cross mark & display bar at the bottom).
Restart
When the center of rotation is aligned with the absolute
center position, rotate the record player again to check that the eccentricity
of the record is gone (or reduced) and then play the record.
* Be sure to rotate the record player (33 rotations or 45
rotations) when measuring. If the record player is not spinning, the stabilizer
will not be in measurement mode.
