Metrum Acoustics appears to be a defunct or inactive audio brand that historically specialized in producing high-quality digital-to-analog converters (DACs) for audiophile and professional audio systems. The company focused on advanced DAC technology designed to provide superior digital-to-analog conversion with emphasis on musical accuracy and technical precision. Their products would have served discerning listeners who demanded exceptional digital audio reproduction capabilities. However, extensive research indicates that Metrum Acoustics no longer maintains active business operations, with their website showing expired security certificates and no current market presence discoverable. The brand appears to be defunct, with no current website accessibility, social media presence, or ongoing business activities. Without accessible current information or verifiable market presence, Metrum Acoustics' specific geographical location, operational timeline, and the circumstances surrounding their business closure remain unclear. The company is presumed to be no longer active in the contemporary audio DAC market.
