The Industry Leader In Affordable Analog Products

Pro-Ject Audio Systems was founded by one of Austria’s leading high-end audio distributors, Heinz Lichtenegger, in early 1991. A genuine music lover and a dyed-in-the-wool audiophile, Heinz challenged the common “cost-no-object” approach to analog audio equipment by manufacturing turntables, tonearms, and accessories at a reasonable price without compromising build quality or sonic performance.
