Overview
A CD transport in 2025? The question is worth asking. Yet Primare provides a coherent answer with the DD15, a unit that claims to do only one thing: extract the digital signal from a compact disc with the greatest possible precision. Lacking a converter, it leaves this task to an external DAC or to the digital inputs of an amplifier, which avoids paying twice for the same function when the rest of the system already provides it.
A mechanism derived from the automotive industry
The choice of the reading mechanism is anything but trivial for a CD transport. Primare has opted for the Philips CDM-M10, a slot-load mechanism originally designed for car audio equipment. This origin explains its intrinsic qualities: proven reliability in harsh conditions and effective isolation from vibrations, whether they come from outside or from the device itself. Discs are inserted without a tray, in a single motion, with a mechanism that gently pulls the CD in. The DD15 accepts standard audio CDs as well as CD-R and CD-RW burned in PCM, but is limited to 12 cm discs – 8 cm mini-CDs are not supported, nor are SACD and DVD Audio formats.
Power supply and digital signal
The power supply combines two distinct topologies depending on operating mode. In standby, a switching circuit keeps the device at a minimum power consumption level of 0.5 W. As soon as playback starts, this section switches off and a dedicated linear power supply takes over to provide stable current to the critical circuits. This hybrid architecture aims to reconcile energy efficiency with signal purity during listening.
The digital outputs offer the two usual standards: a coaxial output on RCA connector and an optical Toslink output. Both transmit a 16-bit / 44.1 kHz PCM stream, in line with the CD Audio format. The signal must then reach a digital-to-analog converter to become audible – that of an integrated amplifier from the Primare range such as the I15 Prisma or SC15 Prisma, or any other quality external DAC.
Compact format and system integration
Primare’s 15 series adopts a so-called “three-quarter” form factor, noticeably more compact than traditional hi-fi components. At 430 mm wide, 385 mm deep, and 106 mm high, the DD15 fits easily into spaces where standard-size electronics would be problematic. Its 6.6 kg weight nonetheless reflects serious construction.
The control connections make integration into a more elaborate setup easier. The RS-232 port allows connection to a home automation system such as Crestron. The 12 V trigger inputs and outputs synchronize power on and off with other compatible devices: connect a trigger cable to the amplifier and the entire system wakes or shuts down with a single command. IR in/out sockets allow remote infrared reception via an optional repeater, convenient when the device is hidden in a cabinet.
Interface and everyday use
On the front panel, an OLED display shows elapsed or remaining time, per track or for the entire disc. Navigation is handled via the front-panel buttons or the supplied C25 remote control, which offers standard playback commands along with search and programming functions. The display does not support CD-Text, a limitation to note if your discs contain this metadata.
Available in black or titanium finish, the DD15 follows Primare’s Scandinavian design tradition: clean lines, uncluttered front panel, no frills. This visual simplicity reflects a design philosophy that the Swedish brand sums up with the term “lagom” – neither too much nor too little, just enough.

Frequently Asked Questions
Can the DD15 be used without a Primare amplifier?
Absolutely. The DD15 works with any DAC or amplifier that has a coaxial or optical digital input. Compatibility with the Primare range is just one option among others, chosen for aesthetic harmony and system coherence.
Does the DD15 play MP3 files burned onto CD?
No. The DD15 is limited to discs that conform to the Red Book standard (CD Audio) and to CD-R/CD-RW containing PCM files at 44.1 kHz. Data discs with compressed files are not recognized.
Which digital output should I prefer: coaxial or optical?
Both carry an identical signal. The coaxial output is often preferred for its more robust physical connection and the absence of optical-electrical conversion, but any audible difference largely depends on the receiving DAC. Optical has the advantage of providing galvanic isolation between the two devices.
Does the 12 V trigger work with devices from other brands?
Yes, provided those devices have a standard 12 V trigger input or output on a 3.5 mm jack. It is a widely used protocol in the hi-fi and home cinema world.
Why doesn’t the DD15 play SACDs?
The Philips CDM-M10 mechanism is designed exclusively for standard audio CDs. SACD playback requires a different optical system and a specific license. With this model, Primare chose to focus on traditional CD playback.
Is there a mobile app to control the DD15?
No, the DD15 is a CD transport without network functions. Control is via the supplied infrared remote control, the front-panel buttons, or a home automation system connected to the RS-232 port.
