ESS Technology Introduces the SABRE PRO Series of DACs Setting a New Performance Bar with Unprecedented 140 dB Dynamic Range
CES 2016 – Las Vegas, NV - ESS Technology today announced its new professional series of Digital-to-Analog Converters (DAC) targeted at premium audiophile and recording studio equipment. The flagship offering for this professional series is the ES9038PRO SABRE DAC. This first member of the ESS PRO SABRE series sets a new benchmark in high-end audio by offering the industry’s highest dynamic range (DNR) of 140dB. The ES9038PRO also offers impressively low total harmonic distortion plus noise (THD+N) at -122dB in a 32-bit, 8-channel DAC.
“The immersive nature and quality of the audio experience that listeners value is a direct result of how well the digital source material is converted to the analog sound that human ears understand,” said Dan Christman, ESS’s Chief Marketing Officer. “Our audiophile and professional customers are constantly driving us to push the technical envelope to deliver better performance and enhance the listening experience. We are very pleased to announce that our new PRO series, with the flagship SABRE ES9038PRO, takes that experience to a new level, both for the home and professional studio environments.”
Technical Specifications
The ES9038PRO SABRE DAC features ESS’s patented 32-bit HyperStreamDAC technology. The HyperStream architecture is responsible for both the outstanding sound quality of ESS PRO SABRE DACs and the extremely low THD+N. Other 32-Bit 8-Channel DACs, using typical delta-sigma architecture, feature –107 dB THD+N (0.0004%), which when subjected to individual listening tests do not equal the clarity and sound stage of the ES9038PRO. This new flagship SABRE DAC was created to integrate seamlessly with both the existing and future portfolio of ESS headphone amplifiers as well as other audio building block technology.
Designed to Recognize and Realize the Artistic Vision
The ES9038PRO SABRE DAC 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. Studio environments can also leverage the ES9038PRO SABRE DAC’s industry-leading performance for professional audio workstations and other equipment. The PRO series enables studio professionals to recreate popular signature sound styles, using external DSP and specialized software packages, while remaining true to the artists’ musical vision.
The Complete SABRE PRO Series of DACs
In addition to the SABRE ES9038PRO, ESS is also announcing other members of the PRO series - the ES9028PRO and ES9026PRO SABRE DACs. These 32-bit, 8-channel PRO series DACs are designed for the audiophile/enthusiast who demands the high quality and performance of a SABRE DAC at a more economical price point. The ES9028PRO and ES9026PRO are pin-compatible upgrades for previous generation ESS products—the ES9018S and ES9016S – and feature 129 dB and 124 dB dynamic range (DNR), and -120 dB and -110 dB total harmonic distortion plus noise (THD+N).

AK4497, A New Flagship Premium D/A Converter has been developed enabling the Highest Sound Quality and Performance available from AKM.
The AK4497 is a new generation premium 32-bit DAC based on AKM’s VELVET SOUND architecture that has been widely adopted by well-established high-end audio companies. High signal to noise performance is achieved by improving VELVET SOUND technology by supporting a larger current drive capability. The performance of an audio DAC using switched capacitor is expanded to the limit with the AK4497. In addition, AKM has developed an original process that has greatly improved low noise performance and electric margin for audio devices, increasing data amount and enhancing original acoustic sound that can be found in the sound strength.
● Dynamic Sound Playback with Large Amount of Playback Information: VELVET SOUND architecture is improved
Not only circuit designing but also the LSI manufacturing process was newly developed at AKM exclusively for AKM’s audio devices. The AK4497 is the first device to utilize this process in AKMs foundry. 32-bit processing is integrated for the IRD (Impulse Response Designed) Filter, reproducing a detailed and natural signal wave. A low-dispersion short delay filter was newly added to the other five filters found in our previous generation device. So, six different digital filter types are selectable according to the user audio and system preferences.
● AKM’s Best Performance D/A Converter
Low-distortion technology achieves industry’s best performance of -116dB THD+N DAC with 128dB S/N characteristic. The AK4497 has the best performance among AKM’s D/A converters. In addition, OSRD (Over Sampling Ratio Doubler) technology greatly reduces out of band noise.
● Supporting High Resolution Data
The first in the industry, a 22.4MHz DSD input is supported. The digital input supports up to 768 kHz PCM and 22.4 MHz DSD (Direct Stream Digital), recreating high-resolution sound that is as close as possible to the original acoustic source.
[Features]
● DR, S/N: 128dB (Mono mode: 131dB)
● THD+N: -116dB
● Sampling Rate: 8kHz ~ 768kHz
● DSD Input: 2.8MHz, 5.6MHz, 11.2MHz, 22.4MHz
● 32-bit Digital Filter (6 types)
● Low Distortion Full Differential Output
● Power Supply: Analog: 4.75 ~ 5.25V, Digital: 1.7 ~ 3.6V
● Operation Temperature Range: -40~85℃
● Package: 64-pin LQFP, 10 x 10 mm
