Portable CD player with a resistor-ladder DAC, headphone/line outputs and USB DAC mode.

Evidence checked: 2026-10-11. Manufacturer/distributor documentation; no independent SoundPath Lab test.

What the documentation establishes

• Proprietary R2R DAC and QCC3095; separate hardware from DM15.
• USB-C data input and separate power/charging; 3.5mm/4.4mm headphone and line outputs.
• Shared 3.5mm optical/coaxial output; USB DAC up to PCM384kHz/32-bit and native DSD256.
• Bluetooth is transmitter mode; the R2R table does not list aptX Lossless.

Best for

Physical CDs and a USB source feeding existing headphones or an external DAC.

Avoid if

You need a Bluetooth receiver or proven sonic/reliability advantages from DAC topology.

Limits and unresolved details

Power and battery depend on output, mode and load; those figures are not transferable between the two hardware models.

Support and purchase checks

Confirm the complete regional model, required cables and external components, current manual/firmware, local warranty and actual dispatch with the official channel. App and streaming-service support depends on current versions; paid services may require subscriptions. A planned release or an order button does not prove local stock.

Keep an existing system that already meets these connection and use requirements. No measured sound-quality upgrade, reliability score or automatic purchase recommendation is assigned.
