The Acryl-IT E upgrade platter for Pro-Ject Audio Systems' Elemental, Primary and Essential turntable models delivers an improved sound performance compared to regular wood, plastic or metal platters. Acrylic is acoustically inert, and offers no colouration inside the audible frequency band for a pure, true-to-life audio performance. Acrylic is also an ideal platform for vinyl records, so for optimal performance the Acryl-IT E is best used without a turntable mat.
