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.

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.
the Numerous filters and their slopes can be selected and set by remote control. 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 D2 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 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 .
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 large resources invested in the D2s in the output buffer amplifier circuits greatly extend the limits of its performance as a line driver. Characterized by 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 D2's top-level buffer circuit configuration features four modules for the RCA outputs and two circuits each for the + and - terminals of the XLR outputs. Maximizing its ability to deliver instant current output, the D2 reproduces the full dynamic range of music with breathtaking realism
