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.

We will open the LineaSonora enquiry form with this product and your chosen version. No order or appointment is confirmed.

Planning your system

The DMS-650 supports network playback over Ethernet or Wi-Fi. The official quick-start guide specifies using one network connection rather than both at once. Consider router location and whether your music comes from a NAS, a computer or an online service. Match the chosen analogue output to your amplifier input, and confirm firmware and current support for the service you plan to use.

Editorial Reference

Model context

Position within the Cary range

Gateway to the DMS platform following the DMS-550: dual AK4497EQ, integrated NAS, and TruBit upsampling with PCM to DSD conversion.

Why choose this model?

The DMS-650 is the official entry point to the DMS platform, featuring MQA, Wi-Fi ac, integrated NAS, and the TruBit upsampling algorithm, without the investment required for the conversion capabilities of the DMS-700 or DMS-800 PV.

For which system does it make sense?

  • First Cary network player with access to the DMS family, Roon Ready, and MQA.
  • Network-shared storage on USB/SD drives (NAS function).
  • Compact systems that do not require the conversion density of the DMS-700 or DMS-800 PV.

Differences compared to similar models

Entry-level model of the DMS platform featuring Wi-Fi ac and MQA; positioned below the DMS-700 in terms of DAC chip and the DMS-800 PV in dual mono architecture. Replaces the DMS-550 in the official lineup.

Architecture and Design Decisions

Two AK4497EQ chips form the conversion core. Cary documents the TruBit algorithm for seven-step oversampling and three levels of PCM to DSD conversion, in addition to the NAS function that exposes USB/SD drives on the network. Compatible with MQA with 16× rendering.

Compatibility and Use

It functions as a digital source for any Cary amplifier or third-party units; the DMS user guide shared with DMS-700 and DMS-800 PV documents connections and services.

Official specification limits

It does not employ the AK4499EQ from the DMS-700 nor the dual mono architecture of the DMS-800 PV. The exact chip model is documented as AK4497EQ in the official specification sheet.

FAQ

Frequently asked questions

How does the DMS-650 compare with the DMS-700 and DMS-800 PV?
It is the first tier of the DMS platform by conversion architecture (two AK4497EQ); the DMS-700 and DMS-800 PV use higher architectures. The control app is shared across all three.
Which services and formats does it support?
It plays network services via direct connection (Connect), Roon Ready, AirPlay and vTuner, and supports PCM up to 768 kHz, DSD512 and MQA (16× rendering).
What are OSO and TruBit?
OSO is Cary’s clocking and jitter-reduction stage; TruBit is the selectable PCM upsampling, with optional PCM-to-DSD conversion.
