About DMS-800 PV

When we created the DMS-700, we began thinking about a no holds barred version of the DMS capable of competing with the best of the best in Network Audio Players/Streamers/DACs. First, it would have to exceed the performance of the DMS-700 which is no small feat. After considerable research and design, the DMS-800 Professional Version (PV) was born.

The DMS-800 Professional Version (PV) is a limited-edition marvel. Simply put, the DMS-800PV is our ultimate expression of our famous DMS platform. If the DMS-700 is analog-like, the DMS-800PV IS analog. Bigger, deeper, wider, and smoother in sound, the DMS-800PV is capable of revealing the actual instruments within the recordings and not just the sound of the instruments. This allows for a more dimensional insight into the music, illuminating a more true-to-life sound. Inside, the DMS-800PV is a dual mono design, doubling most everything inside the renown DMS-700. While the DMS-700 utilizes a single digital/analog stage board with a single current output switched resistor 4 channel AK4499EQ DAC (equivalent to 4 DACs), the DMS-800PV uses separate right and left channel digital/analog stage boards. Each stage board has their own 4 channel current output switched resistor AK4499EQ DAC for a total of 8 individual DAC channels for a true fully balanced dual differential circuit. In addition, the DMS-800PV includes a Crystek Oscillator Clock, two separate DSP driver stages, 14 groups of independent regulated power supplies and two independent groups of analog stage regulation power supplies as well as other enhancements. The DMS-800PV has a larger 5” high resolution display and a slightly taller stance than previous DMS models. Inside the DMS-800PV is a marvel of circuitry design regarding power regulation and both digital and analog circuitry.

The DMS-800PV is also Roon Ready and MQA Certified. Like other DMS products, the DMS-800PV allows streaming from on-board TIDAL, Qobuz, Spotify, Spotify Connect, vTuner, or from files stored on a network computer or NAS Drive. If that wasn’t enough, it includes three (3) USB-A ports for listening from connected USB hard drives, flash drives, and even from a SD card. As an extra measure for convenience, the DMS-800PV also includes aptX™ HD input and output (output for Bluetooth speakers or headphones) as well as Airplay.

Additional features include Ethernet or Wi-Fi connectivity, TruBit™ 7-step Selectable PCM upsampling to 768kHz, and selectable PCM to DSD conversion with selectable 3-step DSD upsampling. Digital inputs include Coaxial (x2), Optical (x1), and AES/EBU (x1) as well as Coaxial and Optical digital outputs, RCA and XLR fully balanced outputs, OSO™ Re-clocking, MU-MIMO Wi-Fi, and a full 3-volt output and variable volume control for direct-to-amplifier connection.

MQA (Master Quality Authenticated)
The DMS-800PV includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The DMS-800PV LED glows green or blue to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.
