Inside technologies
The apparent simplicity of our streamers actually hides a complexity and a finesse far greater than it seems. From the choice of the internal components to the embedded software and circuit topologies, each step of the development process has been essential to enhance the listening experience.
Concept
Two different strategies have been used in our range of streamers.
The philosophy implemented in the Emerson is that of the straight wire: no sampling frequency conversion or data processing is applied, apart from volume control when used. The flow of data from the network interface is transmitted directly to the S/PDIF and AES/EBU modulators of the Emerson DIGITAL, or respectively to the digital-to-analog conversion chip in the case of the Emerson ANALOG. When properly implemented, this solution guarantees a transparent and coloration-free reproduciton.
The Madison features a more complex architecture as it incorporates a signal processing unit (DSP) that hosts our proprietary oversampling process for optimizing input signals. This new interpolation algorithm benefits from the heritage of the iconic modules developed by Anagram Technologies. It significantly improves the digital-to-analogue conversion process in the time domain, without modifying the samples of the incoming data stream.
Network interface
The Madison, as well as both Emerson models leverage Engineered's streaming engine, a proprietary solution based on a Sitara processor from Texas Instruments.
The embedded software, which handles the various network communication protocols and audio stream decoding, has been under continuous development for many years. Internal processes have been optimized to ensure audio data integrity, transmission reliability, support for Hi-Res file formats (PCM and DSD) without transcoding, and a smooth and responsive user experience at the same time.
Clocks
Two clock generators are used alternately, depending on whether the track being played back is sampled at a base frequency of 44.1kHz or 48kHz (as well as any multiples thereof). Our streamers do not include a variable oscillator or a synchronization loop. The stream of audio data is therefore directly cadenced by the active clock.
Additionally, the selected oscillators offer superlative performances, with extremely low phase noise in the audible bandwidth. The distribution of the clock signals has been carefully designed to minimize jitter throughout the digital audio signal path.
Output stages
The Emerson DIGITAL uses two separate modulators for the S/PDIF output and the AES/EBU output. This is the only way to meet the specifications of both standards without having to make compromises. High-speed output stages, synchronized by the main clock to avoid jitter, and two wide bande RF transformers ensure independent isolated outputs and a perfect rejection of common mode problems for superior performances.
For the Emerson ANALOG, a DAC from Cirrus Logic was chosen. This is a well-proven integrated circuit capable of impressive playback quality when optimally implemented. Its power supply, output stages topology and filter circuits required a lot of adjustments, measurements and listening before validating the final solution in accordance with the product philosophy.
