In 2014 EamLab presents the Musica D101, a dac capable of remarkable performance, always innovative and equipped with the first 32-bit conversion chip. Today, in 2021, we present the new MUSICA D201 completely revised and ready for the new high and very high resolution formats. The project revolves around the new ES 9038Pro chip capable of processing PCM signals up to 784 Khz and DSD 1024. the D201 inherits the exceptional technology of the previous model while opening a new chapter in signal processing. It features an MDSD type D / A converter that achieves direct DS signal conversion and supports sources up to 12.666Mhz.
In line with this development, the interface has also been updated to version 2 with significantly expanded sampling frequency and quantization support up to 12.686 Mhz (1 bit 2 DSD channels) and 786 Khz in PCM. D201 also offers convenience and functionality. Digital external sources can be connected via a total of 4 inputs: COAX, Optical, USB and AES / Ebu. It can accept data from a computer, a CD player and SACD, returning the information in musical signals with unprecedented quality and transparency. The front panel display shows not only the sampling frequency of the selected source but also the numerous filters and their slopes that can be selected and set by remote control. the 4 completely separate power supplies, each with a dedicated power transformer, are used to power the digital and analog sections, to avoid any possibility of RF noise or electrical interference that could degrade the sound purity. -The D201 is a digital processor that redefines the concept of "cutting edge" and has its sights set on the future, including streaming-based audio and high-resolution liquid music. Only parts of the highest quality are used in the circuit components and the carefully selected components return an immense wealth of information that results in a spectacular musical experience.

The D201 uses 16 (8 + 8) 32-bit Hyperstream ™ DAC circuits connected in parallel to achieve low noise and phenomenal linearity. Its Saber 9038PRO chipsets are manufactured by ESS. In addition to processing DSD signals directly, a new proprietary processing algorithm performs analog conversion of PCM data with 36-bit resolution for rich, smooth and delicately detailed sound quality. the performance improvement offered by this Eamlab proprietary principle results in output signal noise at very low levels, a feat that is very difficult to achieve with conventional delta-sigma converters. The dedicated Crystek quartz oscillator is used as a master clock to drive the D / A converter in asynchronous mode with the double advantage of also having a significantly reduced jitter .

The high-speed current transmission capability is the most important factor. It is the ability of an analog output circuit to transmit the wide dynamic range of a music signal without loss. the extensive resources invested in the D201 in the output buffer amplifier circuits greatly extend the limits of its performance as a line driver. Featuring a high current output capability, these high performance elements boast an exceptionally high signal rate of change with a slew rate close to 500V / µs as an indicator of its remarkable response speed. The top-level buffer circuit configuration of the D201 features four modules for the RCA outputs and two circuits each for the + and - terminals of the XLR outputs. Maximizing its ability to deliver instantaneous current output, the D201 reproduces the full dynamic range of music with breathtaking realism.

High resolution streaming services usually use PCM encoding as used on CDs. Another option is the DSD encoding used for SACDs. The USB input of the D2 is fully compatible with both PCM and DSDs that many users are interested in. This unit can draw the nuances of encoded music and demonstrate its full potential. The USB input has a maximum PCM resolution of 384kHz / 32bit and a maximum of 5.64MHz for DSD. The S / PDIF input can handle audio up to 192 kHz / 24 bit. Streaming services can deliver up to 192kHz / 24bit for PCM and 2.82MHz for DSD, but the playback specifications of the D2 exceed these. EAMLAB prepared for the further evolution of state-of-the-art sound sources.DSD sta per Direct Stream Digital, una moderna tecnica di codifica digitale che utilizza la quantizzazione per equiparare.
The enemy of data reproduction is jitter, which causes the deterioration of any digital audio signal. The D2 uses asynchronous DSP transmission via dedicated processing which cancels common mode noise from the USB terminal. The S / PDIF input circuit reduces jitter by using asynchronous processing and an integrated DAIR (Digital Audio Interface Receiver). In addition, the introduction of a low-noise clock module contributes to the accuracy of the entire signal transmission.

Only the highest quality parts are used in the circuit components and the carefully selected components return an immense wealth of information that results in a spectacular musical experience.

D2 incorporates the ES9018 32-bit Saber Reference DAC chipset, still widely regarded as the best available. This is surrounded by exceptionally well specified circuitry that puts other similarly priced DACs to shame, including a proprietary discrete master clock to minimize jitter, along with extensive time domain isolation. The HDCATM output stages ensure that the audio signal, after conversion from digital to analog domain, is of the highest quality. D2 processes audio data up to 32bit / 384kHz via USB; this is a far superior specification to that required by current high-resolution music formats, ensuring this new high-quality addition is fully prepared for future advances in ultra-high-definition digital sound. The finely tuned analog section is another example of the awardwinning Balanced Design via proprietary HDCATM design philosophy, according to which the selection of electronic components is not dictated only by specifications, but extensive listening tests are conducted under controlled conditions to determine the best way in which to proceed. At this stage the entire circuit is carefully tuned to obtain sonic accurate signal reproduction .
