Cheseaux-sur-Lausanne, Switzerland | 2020 – After many years of success and esteem, the Nagra VPS is replaced by the CLASSIC PHONO. The VPS, itself inspired by the legendary Nagra PL-P, is a very respected phono stage. The VPS was the base we used and the obvious product to benchmark the new design.
