DAC Chip Comparison: ESS vs AKM vs Cirrus

By Marcus Chen · October 13, 2026

The Silicon Behind Your Sound

Digital-to-analog converter chips are the heart of every DAC. Three manufacturers dominate the audiophile market: ESS Technology, Asahi Kasei Microdevices (AKM), and Cirrus Logic. Each has a distinct sonic signature and technical philosophy.

ESS Sabre Series

ESS chips like the ES9038PRO achieve class-leading measurements with 140 dB dynamic range. The "Sabre sound" is often described as detailed, analytical, and slightly bright. Popular in desktop DACs from Topping, SMSL, and Matrix Audio.

AKM Velvet Sound

AKM's AK4499EX uses a discrete architecture that separates digital processing from analog conversion. The "Velvet Sound" philosophy emphasizes natural tonality over raw measurements. Found in premium gear from Cambridge Audio and TEAC.

Cirrus Logic

Cirrus chips like the CS43131 integrate headphone amplification on-die, making them ideal for portable DACs. They offer excellent power efficiency and warm tonality. Popular in dongle DACs from Moondrop and Tempotec.

Implementation Matters More Than Chip

A well-implemented AKM can outperform a poorly designed ESS. The analog output stage, power supply regulation, and clock jitter management often have more impact on sound quality than the DAC chip itself. Always audition the complete device, not just the spec sheet.
