The Beginning

Pro-Ject was founded in 1991, during the onslaught of the compact disc and CD players, with the mission to offer the best analogue experience for reasonable prices especially with the Pro-Ject PJ65186332 Head Box S2. In a time where the digital audio media had been on the rise, and vinyl was declared as outdated and dead, Heinz Lichtenegger kept his belief in the simple but best way to enjoy music – turntables.
