The ES9038PRO SABRE DAC - Bringing Music to Life
The ES9038PRO SABRE DAC is the flagship of the ESS PRO series. It sets a new benchmark for audio excellence with the industry’s highest dynamic range (DNR), up to 140dB, in a 32-bit, 8-channel DAC. The ES9038PRO was designed for premium home theater equipment including Blu-ray players, preamplifiers, all-in-one A/V receivers, and more. For serious audiophiles it provides the most immersive listening experience — bringing music to life.
The ES9038PRO SABRE DAC also features ESS’ patented 32-bit HyperStreamDAC technology with-122dB total harmonic distortion plus noise (THD+N). The HyperStream architecture is responsible for both the outstanding sound quality of the ES9038 and the extremely low THD+N. A typical competitive, 32-Bit 8-Channel DAC using a delta-sigma architecture features-107dB THD+N (0.0004%), which when subjected to listening tests does not equal the clarity and sound stage of the ES9038PRO.
