Pro-Ject Clamp it

The sound quality of vinyl records improves significantly when unwanted resonances that occur during playback between the record and turntable are reduced. For this reason, the platter and platter should form a close connection.

Conventional plate pucks try to achieve this goal by their high dead weight, which can have 2 main disadvantages:
1) The higher weight causes an increase in rumbling, because the main bearings of inexpensive record players are not so high quality.
2) Instead of the desired closer contact between plate and plate, the opposite is often achieved: Due to the high weight in the middle of the plate, a bowl is formed whose edge has no contact with the platter.
Both of these factors can reduce playback precision audibly.

Clamp it avoids both errors and represents the ideal solution. The clamping mechanism is simply placed on the central axis of the platter, without weight increase and the associated rumbling. The contact pressure can be finely adjusted according to the degree of curvature of the plate. Can be assembled within seconds! Due to its high-quality design Clamp it is not only acoustically but also optically a jewel that enhances every turntable.
