ES-001 Eccentricity detection stabilizer

The world's first eccentricity detection stabilizer (patent applied)

Details

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 record playing surface. 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. Simply put, when using even the finest quality turntables available, the overall wow and flutter of the entire system can only be significantly reduced if the eccentricity of the record is corrected. To faithfully reproduce the source material, it is imperative to reduce the record eccentricity as much as possible.

Excessive wow and flutter present two problems

The first is that the unstable rotation causes fluctuations in pitch across the frequency range. Second, 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's ability to accurately track the groove, resulting in a muddy sound and an unstable sonic image. As a result, the listener will not realize the full potential of even the highest-quality systems. Correcting this eccentricity as much as possible allows you to unlock much more of the potential performance from your equipment.

Adjustment in 3 Steps

step.1 Measurement: When the record player platter is rotating, the upper part of the stabilizer is held to stop the rotation of the stabilizer, while the lower portion allows the platter to spin freely. The stabilizer will detect the rotation and shift to the measurement mode. While in measurement mode, the display on the outer circumference of the stabilizer starts to rotate, and the [Tap to start measure] button is displayed. Next, press the [Tap to start measure] button; the display changes to the [Measuring] button, and the measurement will be completed in about 2 seconds.

step.2 Adjustment: Stop the record player when the measurement is complete. Next, while looking at the stabilizer screen, adjust the record to bring the cross mark (center of rotation) as close as possible to the absolute center position. The level of adjustment will depend on how much play the center hole of the record has. Even a slight adjustment will create an audible improvement. The degree of eccentricity of the record is indicated by the color of the screen (outer circumference, cross mark & display bar at the bottom).

step.3 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. *Make sure the record player is spinning (33 rotations or 45 rotations) when measuring. If the record player is not spinning, the stabilizer will not be in measurement mode.
