Reference 8-Channel Audio DAC

The Sabre Reference (ES9008) Highest Performance Audio DAC is the world’s first 8-channel audio DAC to bring true professional digital audio to the consumer home entertainment market.

Using ESS’ patented HyperStream® architecture and patent-pending Time Domain Jitter Eliminator, the Sabre Reference Audio DAC outperforms the best audiophile equipment with unprecedented 134dB DNR and –118dB THD+N, delivering true studio quality audio to digital audio applications such as Blu-ray, SACD, DVD-Audio, DVD, CD, home theatre, set top boxes and digital TV.

The Sabre Reference’s flexible input architecture accepts SPDIF or PCM data from 16-24 bits up to a 192 kHz sampling rate, and also accepts 1-bit DSD data supporting native SACD audio.

The Sabre Reference sets a new standard for high quality audio performance in a cost effective, compact, easy to use form factor for today’s most demanding digital audio applications.
