Major Technical Differences
The battle between ESS and AKM is not just about brand legacy but also about the underlying technologies that power them. Let’s dive deep into what makes them distinct.
- Conversion Methods
- ESS: Predominantly uses Delta Sigma modulation. This method oversamples the digital signal, leading to precise and sharp sound output. It’s efficient but might sometimes come across as too clinical.
- AKM: Shows a clear preference towards the R2R ladder technique. It produces sound that’s closer to analog, preserving the warmth and musicality.
- Chip Architecture and Design
- ESS: The HyperStream architecture stands out, ensuring precision at every step of sound reproduction.
- AKM: VELVET SOUND architecture is AKM’s crown jewel. It promises—and delivers—a soundstage that’s deep, warm, and true-to-life.
- Signal-to-Noise Ratio and Distortion Levels
- ESS: Known for its towering SNR, ESS DACs ensure that the sound remains clear and free from any noise. The emphasis is on clarity and precision.
- AKM: While AKM also has a good SNR, its emphasis is more on delivering a natural sound, even if it means sacrificing a bit on the SNR front.
- Power Consumption and Efficiency
- ESS: ESS chips are crafted for efficiency. They manage to deliver high-quality sound without draining a device’s battery.
- AKM: AKM chips, while rich in audio output, can sometimes be a tad more power-consuming. It’s a trade-off for the richer audio experience they offer.
