Primare CD31 CD Player – Silver

Faulty. Unit works as a transport only. Internal DAC does not work. Analogue out not working. Signal not coming out of DAC / Processor section. Unit has been to the UK importer and is unrepairable to be sold as transport only.
Some scratches on left side
Some slight rough dark patches on top

******************************************************

Here is your chance to pick up a bargain item from Scandinavian brand Primare. It is a CD31 CD player that has a bit of a problem. Basically the digital to analogue conversion portion of the unit is no longer working and our information leads us to believe that repair is not really an option. However the good news is that the transport mechanism is working fine and connection to a standalone DAC means that you will get a high quality sound at a much reduced price. There are a couple of minor cosmetic marks but nothing of any great significance. It also comes in original packaging with remote control and mains cable.
Primare say….
Every component of the CD31, from the CD transport to the audio output stage, has been designed to achieve the highest possible audio performance.
Careful design for mechanical stability – The Primare CD31 Compact Disc Player uses an advanced DVS mechanism. As with all Primare units, the CD31 Compact Disc Player is housed in an alloy heavy gauge steel chassis, which provides strength, rigidity, and screening, while being effective at damping vibrations from external sources.
Display and audio circuits are isolated – The front panel design isolates the display circuitry from the audio circuitry to avoid interference
The purest digital stream – From the CD-transport we extract the SPDIF signal, which is fed to a DIR1703 digital receiver. DIR 1703 has excellent jitter suppression abilities ensuring that the DACs receive as clean a digital signal as possible – giving the most natural sound. We have chosen not to incorporate any other signal treatment such as up-sampling, which can colour the sound.
Balanced design all the way to the outputs – For precise digital to analogue conversion, the CD31 uses four 24 bit/96 kHz Burr-Brown
PCM1704 K-graded DACs – one of the best analogue to digital converters available today. The DACs are configured in a truly balanced configuration: two DACs per channel. Each DAC carries the same signal with opposite phase. On the receiver side (before the DACs) the
signals are mixed, and since any interference that has arisen during the transmission will be present in both lines with identical phase, such noise and distortion products are cancelled out leaving only the pure original signal. Interpolation filtering is carried out by the excellent
DF1704. Each DAC uses its own current to voltage converter stage, Burr-Brown’s OPA2134, a sonically excellent operational amplifier. The signal path is finished in a single-ended output stage with a discrete Mosfet transistor driven by an active current source instead of the use
of passive resistors.
Shortest signal paths – SMD technology is used whenever possibly to keep the signal path as short as possible.
No compromise power supply for the best possible performance – Each part of an electronic design has specific power requirements. Primare’s forensic approach to ensuring that clean power is supplied throughout the design is a key part of its design philosophy and has significant sonic benefits.
An internal mains filter ensures that any high frequency disturbance is removed before it reaches the power transformer, which is placed as far away as possible from the delicate analogue circuits. The player incorporates a fantastic R-core transformer with separate windings for all of the player’s different power requirements (mechanical, analogue, digital, etc) – eight in all! Each is individually regulated in thirteen steps to ensure that enough power is constantly available. For the critical analogue audio stage, the player incorporates ultra-fast discrete power regulation, ensuring that enough regulated power is available for even the deepest sonic transient that can be recorded on a compact disc.
This power supply configuration together with different ground planes for all kinds of signal layers gives the player the usually extremely high signal to noise ratio allowing you to take full advantage of the dynamic range possible with CD.
Power in standby mode: analogue audio sections are supplied with mains power in standby mode. This means that no run-in time is necessary for the player when activated from standby mode. Its performance will be the same as if it were left in operating mode continuously.
The analogue output provides for both the recommended balanced XLR outputs and the conventional unbalanced RCA for connection with an appropriate stereo amplifier.
The CD31 Compact Disc Player provides one RCA co-axial 75 ohm S/PDIF, one optical TOSlink and one professional XLR 110 ohm AES/EBU digital output for connection to a digital preamplifier or digital surround processor.
Intuitive user interface – In keeping with the philosophy of the Primare range of systems, the CD31 can be controlled through a very simple and intuitive interface, designed so that it will not distract you from the pleasure of listening to music on your system. In fact, most of the features of the CD31 can be accessed through just six front panel push buttons. The full set of functions, including scan and programming, is available using the remote control supplied with the CD31.
