Pro-Ject: projecting sonic purpose and premium playback performance
Since its founding in 1991, Pro-Ject has pursued a singular mission: to provide premium analog listening experiences for music lovers. During a time in which the succession of CDs and digital audio over analog and vinyl seemed all but inevitable, company founder Heinz Lichtenegger doubled down. Heinz and his talented team were determined to introduce new listeners to the world of genuine, true-stereo, hi-fi audio, complete with a menu of value-laden products. Considering that the RIAA reported that vinyl outsold CDs in 2022 — the first time it had done so since 1987 — it’s clear that Pro-Ject’s long-term wager paid off. The company’s initial major success stemmed from the release of its debut turntable, the Pro-Ject 1. Since then, Pro-Ject has materialized as a worldwide window into the world of high-fidelity analog listening. The company collaborates with manufacturers, engineers, and designers around the world to produce parts from scratch, ensuring everything from the smallest screw to the most complex components maximizes quality. This all-encompassing commitment has manifested in an extensive line of turntables, speakers, cables, amplifiers, tonearms, cartridges, and more. Whether you’re a newcomer to the format or a veteran collector, Sweetwater invites you to chart your vinyl voyage with Pro-Ject — supreme style and sonic substance are only the beginning.
