Singxer

Overview

Singxer is a China-based audio manufacturer specializing in high-performance digital and analog audio products. The company initially built its reputation through OEM and ODM work for third-party manufacturers, during which it developed expertise in XMOS digital audio processing and proprietary technologies like their SHDPLL digital phase-locked loop system. In recent years, Singxer has expanded into branded consumer products, including USB digital interfaces, headphone amplifiers, and integrated amplifiers, positioning itself between larger Chinese audio brands and boutique manufacturers in the enthusiast audio market.

History

Singxer was founded in 2011 as an electronics team based in Guangzhou, China, initially focused on OEM and ODM projects for the audio industry. The company gained recognition for its technical expertise, particularly in XMOS audio processing, and was instrumental in developing and optimizing XMOS's second-generation xCORE-200 series processors. In recent years, Singxer transitioned from contract manufacturing to releasing branded consumer products, beginning with digital interfaces and expanding into analog amplification with the introduction of their SA-1 headphone amplifier.
