This Pro-Ject upgrade kit is designed for Pro-Ject vinyl turntables with a suspended motor, and more specifically for the following models: DEBUT, 1, 2 and 3, P1, P2, X-pression, RPM3, 4, and 5, Anniversary, ART-1…
Pro-Ject upgrade kit: composition
It includes two black screws, two TPE vibration isolation bushings, a new perfectly adjusted aluminium pinion and a black silicone cylindrical belt.
It is quite simple to set up, the most difficult part is to remove the OEM pulley. A screwdriver is required for this. The one that comes with some cartridges will do the trick.
Pro-Ject upgrade kit: operating
You probably wonder how these simple parts can improve the sound of your vinyl turntable?! Actually, the OEM suspended motor generates a lot of vibrations and oscillations partly stemming from voltage fluctuations. Although they are mostly minimised with the use of a Speed Box, they can still be quite significant.
Our readings showed us that they primarily appear at 50 and 100 Hz. Many harmonies stem from these fundamental frequencies, actually placing these problems between 32 Hz and 64 Hz and 80 Hz and 120 Hz. They fall within the audible spectrum and are transmitted to the cartridge via the belt and platter.
Pro-Ject's solution is quite simple: the two bushings mechanically and acoustically isolate the turntable motor and the new pinion - adjusted to the new round belt - minimises noise and oscillations from the platter and hence the cartridge.
Pro-Ject upgrade kit: listening and review
The result on playback is in line with our readings: The sound is clearer and more textured.
The blur on the cellos has completely vanished and the tempo is a lot more vibrant.
An essential!

Great Upgrade Kit
The kit is excellent, my Pro-Ject RPM 5.1 with Ortofon 2M Black and Pro-Ject Gound It DeLuxe had already enjoyed the addition of the Pro-Ject Speed Box S that had greatly reduced the vibrations of the engine but with this Kit the engine body becomes mute, the vibrations transmitted are imperceptible to the touch of the engine while before they were even after the introduction of the Speed Box. The most difficult part was the change of the pulley which, if you do not take precautions, could break the locking screw. The video of maPlatine is very clear and easy to install the kit. The only suggestion I would like to give is not overtight the screws, otherwise the rubber insulation effect will be reduced. In the video, in my opinion, they were too tight, I narrow them slightly less. For the results, when the vinyl allows it, I detected much more transparency and detail, with better focusing of the scene. I can I say ....absolutely recommended.

Attention au démontage
Je n'ai pas pu le monter! En voulant dévisser la poulie d'origine, la tête de vis a cassée... fin de partie!
Sinon, Maplatine toujours performant sur les livraisons, commandez les yeux fermés
ce kit donne nue bien meilleur définition, le problème de "rumble" audible entre les morceaux à disparu, les silences sont plus silencieux !!!! trés content ! merci
Cette modification est simple à faire surtout avec l'aide de votre video, merci ! Le resultat sur ma Xpression est audible. la musique est plus dynamique et le grave me parait moins sale et flou. à conseiller.
