Cary Audio DMS-650 Streamer

ABOUT THE DMS-650 NETWORK AUDIO PLAYER

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.
