What makes the exaSound s82 Mark II Roon Server, Streamer and D/A Converter exceptional and different?

Old school audiophiles understand that separate audio components have advantages over the all-in-one devices. The modern lifestyle demands smaller systems, simplicity and easiness of use. The s82 Mark II is built and operates like three standalone audio devices and offers the convenience and the ergonomic simplicity of having one stylish audio component.

Power Quality via Electrical Isolation

Minimizing noise is one of the three foundations of high-end sound reproduction.

Standalone DAC and server audio components would be powered by their own power supplies. To achieve reference grade sound purity, the s82 Mark II can use two external power supplies for the DAC module and the server module and 16 internal power conditioning stages. One of a kind in-house developed four-way Galvanic isolation decouples electrically the power lines and the ground plates of the DAC, the Roon server, the USB/Streamer and the SPIDIF/Optical inputs. The achieved vanishingly-low noise floor brings outstanding micro-dynamics and realism of the sound.

Compartmentalizing noise sources with the use of two external power supplies, Galvanic isolation and multiple cascaded power conditioning stages brings vanishingly-low noise floor that contributes to the micro-dynamics and realism of the sound.

Jitter-Free Streaming via "Timing Isolation"

Minimizing jitter is the second foundation of high-end digital sound reproduction.

Jitter is very small random clock error. For audio it means that a note is played just before or after its time. This makes the sound to be perceived as unnatural.

exaSound developed the s82 Mark II with "Timing isolation" between the embedded server, streamer and DAC that makes them to operate like three standalone audio devices that are not affecting each-other with the timing irregularities of their engines and the jitter caused by the digital audio connections between them.

The combined effect of using exaSound's proprietary, asynchronous packet streaming with data error correction, embedded master femto-clock with three auxiliary stream-control clocks and super fast FPGA engine makes the s82 Mark II virtually jitter-free. This affords sound realism , transparency and detail.

Reference-Grade Low Distortion via D/A Conversion and Proprietary Fully-Balanced Output Stages

Low distortion is the third foundation of high-end digital sound.

The refined D/A converter, the proprietary fully-balanced low-noise output stages and the high-resolution volume control put together deliver extremely low distortion levels. The exaSound s82 Mark II is transparent like crystal. You don't notice it being present in your system. It adds no spices or sweeteners to the sound. It wears no makeup. The sound is honest and dynamic, very life-like, as close as it gets to the sound of real human voices and acoustic instruments.

Multiple power sources isolated from each-other deliver clean low-noise power. Bit-perfect streaming delivers error-free audio data. Asynchronous operation eliminates all jitter cased by streaming, external USB and network connections.

In conclusion, we've built the s82 Mark II from the ground up with in-house developed hardware, firmware, software, true-asynchronous streaming protocol and state-of-the-art fully balanced output stages. Put together, they create the perfect operating environment for the ES9038PRO DAC chip. We don't use third-party OEM modules. The well integrated and refined hardware and software technologies developed in-house give us full control over the sound-streaming chain and deliver vanishingly low noise, distortion and jitter levels. This makes the exaSound difference and this is why the reference-grade s82 Mark II sounds distinctively more natural, dynamic and transparent than other DACs based on the same D/A monolithic converter.
