DS Audio ES-001 Eccentricity Detection Stabilizer

Is the idea to use the ES-001 as the record clamp? Otherwise, isn’t there a high risk the record will move when you take off the ES-001 and put on your clamp?

correct ... once you have aligned the record using the ES-001 it stays in place as the record clamp

You can certainly use ES-001 as a record clamp. The base is made of tungsten which is a good material for clamp. If you have other better clamps, it may be better to use them instead.

It is not easy to move the record once it is placed on the platter. You really need to push on the edge to move it. Changing to another clamp will not move the record. The downside of ES-001 as a clamp is its loose components. It rotates on its own. The mass is not dynamically balanced, ie the weight is not evenly distributed around the device.

As usual, actual hearing is the final judge.

I see, thank you both!
So the corrections are very small in most cases.

It depends on what you mean as small. ES-001 gives you a reading for the amount of deviation. In most cases, the reading is more than 50 micrometers.

 

[BillK]

You can.

There’s a risk but it depends on how easily the LP moves on your table.

 

[spiritofmusic]

Quick Q...if the freshly cut centre hole is larger than the platter spindle (by definition must always be), and you play the LP again after any period of time, how rapidly can one reposition the LP *absolutely precisely* when re-playing it? Surely we're talking about fractions of a millimetre in any number of directions.

 

[Zeotrope]

I still don’t see why the record won’t move and ruin its alignment if there is a record weight, or it’s lightly clamped? I can see how it will work with vacuum hold down but if the adjustment is small and the hole in the record is (slightly) larger than it should be for a precise fit on the spindle, why won’t it move while it’s spinning, unless it’s tightly clamped?

I can tell you that I haven’t seen movement after it’s centered an album, noting that I just let go and use it as a record clamp. I haven’t tried a different record clamp after centering the album side.

Can I attach a video? I just shot one demonstrating this concept in action.

If I can’t attach a video and anyone wants to see it … just text me your cell number (or email if preferred) and I’ll send it

Thanks, Greg

Thank you, Greg! That was so nice of you to share a video. Much appreciated!

I just got an ES-001 and tried it on a few records. There is very limited room to adjust the records - I know I can ream them, but I was expecting more play with a standard sized hole. Could it be that my Brinkmann spindle diameter is a little wider than most, at 7.2-7.3mm? I have noticed that some records required reaming just to be able to fit on the spindle.

Another question is how to adjust the record when part of the revolution is actually centered? At some points along one revolution, the record is perfectly centered. If that’s the case, then can you ever have it perfectly centered?

Any answer to my Q from post #26?

Alignment is easy and fast with the ES-001. It will take 1-2 seconds.

So, once the hole is cut out, you just re-use the device on future playback to solely "line up" the record once it's on the platter (no further cutting needed)? It's straightforward to find the "sweet spot"?

Correct, very easy to line it up. After a few times doing it, it’s easy. The hole has to be large enough though.

 

[spiritofmusic]

Hence the need to cut it larger...

Yes but according to Fremer most records do not need to be cut larger. This must depend on your turntable’s spindle diameter. Also, a tapered spindle as on TechDas will not work with the unit at all.

 

[spiritofmusic]

Interesting, most of my vinyl is a reasonably tight fit to the spindle.

That is because you are a large spindle guy Marc !

I thought you might be on that the moment I wrote those words. It's like the last 50 years political correctness never happened, lol.

I probably have to open about 50% of my 250 or so records slightly to center them. I ream them as little as possible, knowing that's a one way street.

I'm not sure on the second question. Clear or colored records typically don't get any signal to center at all for me. I've only had a very few black records do a wobble pattern (what I think you are describing). I'll keep an eye out for that and see if I could solve it (center the album correctly).
