Here's more info about the ES-001 Eccentricity Detection Stabilizer and what it does, as described in DS Audio's own words on the company site:

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.

Put simply, when using even the finest quality turntables, these factors combined can result in an overall wow and flutter value 20 times worse than that of the turntable in isolation. 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 you to unlock far more of the potential performance of your equipment.

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.

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.

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, and ​​display bar at the bottom).

When the center of rotation is aligned with the absolute center position, rotate the record player again to check. 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.

Submitted by Jazz listener on Wed, 2022-06-22 19:06 Sounds like something out of an Austin Powers movie. Log in or register to post comments Is this more accurate Submitted by Tom L on Wed, 2022-06-22 19:40 than the time-honored practice of watching the head of the tonearm closely to see if it goes back and forth? The next step is usually to ream out the center hole a bit and clamp it in the correct position or return the LP.

Then I carefully ream out part of the center hole as needed. Then make a pencil mark on the label, next to the reamed area, so that the next time I play the it, I just push the pencil-marked area against the spindle. Works fine, and it's free.

Hope this helps. Log in or register to post comments I would love to have one Submitted by volvic on Thu, 2022-06-23 10:50 Sadly, the pricing is out of my reach, at least too hard to justify. The other reason, why I don't think this would work is that I also have suspended tables and moving and shifting the record around to center it might not be the best way to keep in tune. Still what a great product. Log in or register to post comments DietChapstick Submitted by DietChapstick on Thu, 2022-06-23 12:20 Very interesting device but the price is simply unrealistic for an normal person. It would be interesting to see them license the technology to a much larger company and get it manufactured at a much greater scale at a lower price. For now I recommend everyone immediately return their off-center records if they are newly purchased LPs and complain loudly to pressing plants that make off-center vinyl. There is really no excuse for it these days and plants need to do a better job with quality in general. Even the plants that press audiophile label stuff need to tune up quality. Log in or register to post comments But how does it work? Submitted by zimmer74 on Thu, 2022-06-23 20:14 Fine, this device can measure eccentricity, but how can you apply correction on a normal deck without reaming out the record hole? The description says "press the record board to bring the cross mark (center of rotation) as close as possible to the absolute center position." Huh? What is the record board? Log in or register to post comments What's the price? Submitted by Zardoz on Fri, 2022-06-24 09:37 Why is the price not mentioned in the report? Or did I somehow miss it? Wouldn't be because it is outrageous, would it? Log in or register to post comments May Not Be For Everyone But Very Usefull! Submitted by Mudfoot on Fri, 2022-06-24 10:23 Well this is neat. As an audio engineer, I’ve spent way too much time getting a disc perfectly centered for digitizing when master tapes no longer exist. (Mostly 45 & 78rpm) This may not be for everyone’s rig but it’s corrective effects have been noticed by every client and fellow record collector I’ve had. Previously correcting off center records involved alot of trial and error. It’s very difficult and time consuming to ‘eyeball’ it, so I’ve made a primitive jig using a lazer pointer to shoot at the concentric run-out groove. Works about 90% of the time. If the record is warped, my jig doesn’t work that consistently. Vintage Jamaican 45RPMs are the worst in all these regards, horribly off centered, many different forms of warps, labels oversized covering the runout groove, sometimes NO RUNOUT GROOVE (i have a studio one 45 that plays well into the label then had the cutting stylus just liffed when the engineer ran out of real estate!). I can expect to spend 10-45mins getting a disc centered for digitizing! 78rpm I’m stuck with the eye-ball technique because the runout groove was cut eccentric as that was the standard at the time. A device that can make this process take only a few minutes would be a dream come true! Assuming this device works consistently, I’m interested to try one. And if they could add support for 78rpm, many other professional Archivists would be interested as well. Any chance you could add a website link to your post for the item please? I’d like to pass this along to some colleagues. Cheers, Jake Log in or register to post comments Price Please Submitted by Lazer on Fri, 2022-06-24 14:13 How much does it cost?
