What are the key differences between the ESS Sabre ES9038PRO and the AKM AK4499EQ?

The ESS Sabre ES9038PRO and AKM AK4499EQ are two of the most advanced DAC chips available, each with distinct characteristics and advantages. Here are the key differences between them:

Technical Specifications

• Resolution:
  • ESS Sabre ES9038PRO: Supports up to 32-bit resolution.
  • AKM AK4499EQ: Also supports 32-bit resolution.
• Dynamic Range:
  • ESS ES9038PRO: Offers a dynamic range of up to 140dB, which is exceptional for capturing subtle audio details.
  • AKM AK4499EQ: Provides a dynamic range of around 128dB, still high but slightly less than the ESS chip.
• Sampling Rate:
  • Both DACs support high sampling rates, with the ESS chip handling PCM up to 768kHz and DSD512, while the AKM chip also supports PCM up to 768kHz and DSD512.

Sound Signature

• ESS Sabre ES9038PRO:
  • Known for its clarity and detail, often described as having a "bright" sound signature. It tends to reveal more intricate details in music, making it suitable for genres where clarity is paramount.
  • Users report that it can sometimes sound harsher in the high frequencies, which may not be ideal for all listeners but can be exciting in dynamic tracks.
• AKM AK4499EQ:
  • Generally characterized by a warmer and more natural sound. It is often described as smoother, particularly in the midrange, which can make it more forgiving with less-than-perfect recordings.
  • This chip is noted for its ability to produce a more immersive experience with vocals and acoustic instruments, providing a sense of emotional depth.

Implementation and Design Considerations

• The performance of both DACs can be heavily influenced by the surrounding components in the audio system. The analog output stage and power supply design can significantly affect the final sound quality.
• Users have noted that while both chips are capable of excellent performance, the implementation details matter more than the chip itself. For example, if poorly implemented, even a high-end DAC chip may not perform well.

Price and Availability

• The ESS Sabre ES9038PRO is typically found in higher-end models due to its advanced features and performance capabilities, often commanding a higher price point.
• The AKM AK4499EQ has gained popularity especially after the AKM factory fire in 2020 led many manufacturers to switch to ESS chips; however, it remains a strong competitor in terms of price-to-performance ratio.

Conclusion

Choosing between the ESS Sabre ES9038PRO and AKM AK4499EQ largely depends on personal preference regarding sound signature and specific use cases. If you prefer detailed and bright sound reproduction, the ES9038PRO may be more appealing. Conversely, if you favor warmth and smoothness in your audio playback, the AK4499EQ could be the better choice. Ultimately, both chips offer exceptional performance suitable for high-end audio applications.
