The DMS-650 is the latest product in our DMS platform. While it replaces the DMS-550, it surpasses the renown DMS-600 in performance. The DMS-650 packs a BIG punch! Much more so than just calling it a “replacement.” Built around the AK4497EQ VERITA DAC (same as our previous flagship DMS-600), the DMS-650 is a no-compromise killer. It delivers gorgeous clarity and richness with a sense of ease that Cary Audio is famous for. It combines wonderful amounts of detail and fantastic bass articulation yet retains a texture of naturalness that makes you forget you’re listing to a digital source, allowing you to fall back into your music. DMS customers are routinely taken aback at the foundation, dimensionality, openness, and transparent sound the DMS delivers. The DMS-650 is capable of native 32-bit / 768kHz PCM and DSD 512. It’s also Roon Ready and MQA Certified. Like other DMS products, the DMS-650 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-650 also includes aptX™ HD input and output (output for Bluetooth speakers or headphones) as well as Airplay.
The DMS-650 has a slight cosmetic redesign that features a black-out appearance (for black units), which includes a black display frame and black power button. For both black and silver units, the right-side groove now includes a “swoosh” design as well as a faceplate devoid of silkscreened logos for an ultra-clean sleek look.
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.

The DMS-650 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The DMS-650 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.
