The Pro-Ject Align it DS3 is an effective cartridge alignment tool designed for easy and precise alignment of turntable cartridges. It features an innovative design that allows users to adjust their cartridges without repeatedly rotating the turntable platter, as it traces the entire path of the tonearm from the outer to the inner null points. This convenience is beneficial for both beginners and experienced users, making the alignment process straightforward. The tool provides three popular alignment geometries: Baerwald, Löfgren B, and Stevenson, each suited for different listening preferences and types of music. Baerwald is a well-rounded geometry, Löfgren B focuses on minimizing distortion in the middle area of a record, and Stevenson optimizes tracking for classical music and longer tracks. The Align it DS3 is compatible with all Pro-Ject turntables and many other manufacturers' turntables, depending on their pivot to spindle distance. Detailed instructions are included to guide users in selecting the appropriate geometry for their listening habits.
