The History of AKM's D/A Converters Since 1989

AKM released a delta-sigma D/A converter (DAC) in 1989.  An advanced multi-bit DAC based on bi-directional DWA, (Data Weighted Average), technology was developed as the first generation premium audio DAC.  In 1998 the 2nd generation premium DAC, and the first 32-bit DAC was released in 2007.
A new generation architecture, the VELVET SOUND brand was launched in 2014.  The 3rd generation premium DAC, VERITA AK4490 was released which achieved an industry best voltage output performance of -112dB THD+N and 120dB S/N characteristic using enhanced low-distortion technology.  Four multi-channel products have now been added to the premium DAC AK445X series. In addition, with best sound quality and characteristics, the new flagship AK4497 was released in 2016.  Seven 32-bit products in total are available in the premium DAC lineup.
The AK4497 supports next generation high-resolution sources up to the 22.4MHz DSD format realizing 128dB SN and -116dB THD+N with AKM's original LSI manufacturing process for high quality sound.  
AKM products have been widely adopted by well-established companies from high-end to consumer uses around the world because of advanced solutions we provide with many years' experience.
