Founded by Alex Peychev, APL Hi-Fi is a boutique manufacturer of high-end audio components, renowned for combining advanced digital design with refined analog engineering. Every product is handcrafted to deliver the most natural and emotionally engaging musical experience possible.

Product Range

APL Hi-Fi designs and builds digital-to-analog converters, music players, and analog components with a focus on native DSD signal processing, discrete analog stages, and time-domain precision. Each design operates in the pure DSD domain, altogether avoiding PCM conversion for ultimate signal integrity.

Design Philosophy

Every circuit, algorithm, and architecture is designed in-house to preserve musical truth. APL Hi-Fi products are known for their purity, balance, and unmistakably analog sound character.

The NSP-GR music server now runs the Linux version of Audirvāna Studio and can be easily controlled by the Audirvana Remote mobile app.
