Purchasing, listening and delivery
Ordering and system matching
Ask about the selected version and matching with your amplifier, sources and room. Supply arrangements will be confirmed in the quotation. An enquiry does not confirm a sale.
Listening sessions and demonstrations
You can request a listening session by appointment at our Barcelona office (Carrer de Modolell, 57). When we arrange the appointment we confirm which equipment is available to hear, along with the date and time.
Home demonstrations are not offered for this product.
Delivery and setup
Delivery, its cost and the estimated timing are confirmed in writing in your quotation, for your delivery address and before you accept it.
Installation and setup can be requested as an additional service. We assess feasibility and quote it separately.
Editorial Reference
Model context
Position within the Cary range
The sole integrated unit of the DMS platform: combines a network player, AKM converter, and Class A/B solid-state amplification within a single chassis.
Why choose this model?
For those requiring comprehensive streaming from the DMS platform and integrated amplification in a single unit, without the need to assemble a separate source, DAC, and power stage.
For which system does it make sense?
- Compact single-box system with streaming, analogue inputs, and directly connected speakers.
- Rooms where DMS connectivity (Spotify/TIDAL/Qobuz Connect, AirPlay, Roon) is desired without separate preamplifier or power amplifier.
- Listen with a subwoofer via the dedicated preamplifier output.
Differences compared to similar models
Compared to the SI-300.2d, it offers full network playback via the DMS platform; compared to the pure DMS models, it adds 75 W/ch (8 Ω) integrated. Wi-Fi b/g/n (not ac) and without the high-resolution codec present in the DMS-650/700/800, according to the official documentation.
Architecture and Design Decisions
Integrates the DMS streaming platform, AKM converter with 8× oversampling, and a Class A/B MOSFET power stage within a single chassis. Cary Audio specifies 75 W RMS per channel at 8 Ω and 125 W at 4 Ω, featuring preamplifier/subwoofer output and coaxial and optical digital outputs.
Compatibility and Use
Speakers of 4 or 8 Ω; subwoofer output; analogue inputs in addition to network connectivity. A compact alternative to the DMS-650 paired with an external amplifier.
Official specification limits
Cary Audio does not document the high-resolution codec present in the DMS-650/700/800 on the web page. Wi-Fi b/g/n, not ac. The exact model of the AKM chip is not published on the web page.

FAQ
Frequently asked questions
- Does the DMS-300A include an amplifier?
- Yes. It integrates a 75 W per channel (8 Ω) amplifier alongside the network and DAC sections, in a single unit.
- Which DAC does it use?
- Cary does not publish the DAC chip model for the DMS-300A, so we do not state it.
- When does it make sense versus a DMS-650 with a separate amplifier?
- The DMS-300A combines network playback and amplification in one box; a DMS-650 with a separate integrated amplifier offers more flexibility in choosing the amplification.
