DAC AK4499 I2S XMOS Bluetooth aptX-HD LDAC UAT Balanced 32bit 768kHz DSD512 MQA
The SMSL VMV D2 is a high-end DAC, embedding high-end components within a neat architecture, for exceptional performances. At the heart of the DAC, the digital to analog conversion stage is based on a AKM AK4499 chip. Furthermore, the D2 is also very versatile, with a full range of connectors and practical functions.
The SMSL VMV D2 embeds an AKM AK4499EQ conversion chip to provide excellent performance and a precise, lively and rich sound reproduction. The Velvet Sound architecture of these DACs allows to reach a very low distortion level and a THD+N measured at -123ddB.
The chip is produced using Premium Audio LSI and non-magnetic encapsulation technology. These improve the performance in terms of noise, especially in the low frequencies.
The D2 benefits from a total support of MQA (Master Quality Authenticated), allowing the device to decode these files in order to reach a sound quality as close as possible to the original recordings. Moreover, the digital output (Optical or Coaxial) of a CD player can be transmitted to the SMSL VMV D2 MQA decoder. The latter will be able to restore the original high resolution signal and confirm it using the MQA signature authentication system.
Integrating a Bluetooth 5.0 Qualcomm CSR8675 receiver, the D2 allows you to broadcast your music wirelessly, directly from a connected smartphone. With the support of the codecs of transmission Bluetooth aptX, aptX-HD, LDAC and UAT, it is moreover possible to benefit from a quality of restitution equal or superior to that of the CD.
The USB-B input of the SMSL VMV D2 is associated to a second generation 16 cores XMOS interface: the XU216. This one ensures the reception and the decoding of audio streams via USB while supporting high resolution files up to PCM 32bit 768kHz and DSD512.
All the circuits of the SMSL VMV D2 benefit from a careful and optimized design, using only high quality components dedicated to audio. In addition to the AK4499EQ DAC or the XMOS XU216 USB interface, the DAC is equipped with two Accusilicon ultra-low phase noise clocks or an ultra-low noise power supply stage with an output noise floor of only 1.8µVrms embedding two Noratel toroidal transformers, to independently power the digital and analog circuits.
A rare but very useful feature, the SMSL VMV D2 allows you to invert the phase of the balanced XLR output. Thus, the pinout of this output adapts to your system for an optimal compatibility.
