Designed and hand-made entirely in Canada

exaSound’s in–house design delivers world recognized, award winning sonic purity 

• World's highest performance Sabre ES9038PRO DAC chip increases 4 times the paralleled DAC channels to bring more presence in the mid-range
• Sophisticated reference voltage sources and master clock power circuits deliver more precise 3D imaging and more natural portrayal of transients
• Each channel has autonomous balanced and unbalanced analogue output stages that can be used simultaneously. Components with superb linearity and separate power lines offer lower noise and distortion levels, fine micro dynamics and natural base reproduction
• Dual-mono output stage topology offers reduced EM interference and reduced channel cross-talk, resulting in better detail and resolution
• Future-proof design allows for upgrades of the output stages, the streamer module CPU, RAM and SSD storage

• ZeroJitter™ — a unique true asynchronous USB interface with error correction assures accurate data reception
• ZeroResolutionLoss™ — an exclusive volume control with four–way volume synchronization brings convenience and dynamic range comparable to the best analogue volume controls
• GalvanicInfinity™ — affords complete galvanic isolation for ultimate external noise reduction
• FemtoMaster™ — our quad-clock architecture, with 82 femtosecond master clock and 3 auxiliary stream-control clocks, minimizes jitter for maximum timing accuracy, image development and bass extension
• Balanced internal design - yields the lowest analog noise and lowest distortion

s82 is a Roon Ready streamer and Roon Tested DAC. It has been profiled and tested by both Roon Labs and exaSound for maximum compatibility with Roon. Roon identifies exaSound devices and sends them audio optimized for their capabilities. Together, Roon and exaSound deliver the power, flexibility, and performance benefits of digital audio, with the easiest setup and highest reliability available.

MQA (Master Quality Authenticated) is a new technology which delivers studio master quality audio using no more bandwidth than a CD quality file – so it can be easily streamed or downloaded. MQA encoded content is available from major streaming services and download sites.

Streaming Options

                

Newly released Tidal Connect support allows the Tidal apps on iOS, Android, Mac OS and Windows to stream directly to the S82 DAC.
The s82 Streaming DAC also offers master-quality Tidal and Qobuz streaming with Roon. It delivers seamless, top-quality sound over wired or wireless connections, accessing high-resolution streaming services and local files. s82 can be used with the Roon Nucleus and with PC and Mac-based audio servers.
exaSound-made Gamma and Delta servers offer tight integration and improved ergonomics when used with the s82 Streaming DAC. The exaSound Delta server offers the highest CPU performance when DSP processing is required with Roon.

Power Supply Options

The s82 Streaming DAC supports two power supply configurations.

Single Power Supply Configuration
the exaSound s82 Streaming DACs is offered with a desktop style 12V switching power supply. The s82 uses 16 internal linear power conditioning stages in cascaded configuration. Every subsystem is powered by dedicated power source. This sophisticated power conditioning makes the s82 very insensitive to the quality of the external power supply.

Using Additional Linear Power Supply for the DAC Analogue Stages
To achieve the lowest possible noise level, a third-party 12V linear power supply can be used for the DAC analogue circuits and IV stages.
