AK491x Premium Audio Op Amps – Asahi Kasei Microdevices (AKM), a subsidiary of Asahi Kasei, has unveiled the AK491x series of premium audio operational amplifiers (op amps). These new devices mark a significant expansion of AKM’s analog audio portfolio and will be on display at HIGH END Vienna 2026 from June 4th to 7th at Austria Center Vienna in Hall X2, Booth E07.
AKM extends its VELVET SOUND™ philosophy beyond the DAC (digital-to-analog converter) and into the analog output stage with the introduction of the AK4911 and AK4912, single- and dual-channel op amps.

“These are groundbreaking specifications, but the AK491x series was designed with a focus on the listening experience,” said Seiko Nakamoto, Lead Expert – Audio Product Development. “Sound quality cannot be fully defined by numerical values alone. AKM’s development process placed equal emphasis on volume balance, transparency, spatial expansion, and perceived weight. The next frontier for sound quality lies in op amps that achieve both outstanding measured performance and a qualitative musical experience ‘as if you were there.’”
The Asahi Kasei Microdevices booth at HIGH END Vienna 2026 will showcase the AK491x series along with a sound-field correction demonstration for home audio. Technical discussions and listening sessions conducted by AKM engineers and Audio Meisters will be available by appointment at booth E07.
Samples of the AK491x series op amps are currently available, mass production scheduled to start in early 2027. To learn more about the AK491x series, visit: https://www.akm.com/global/en/products/audio/.
