Pioneer Hi-Res XDP-300R portable audio player


Pioneer has released the XDP-300R Hi-Res portable audio player capable of playback up to 11.2MHz DSD, 384kHz/24bit FLAC/WAV, and the newest High Res technology MQA, with full balanced circuitry for the dual DACs to output.

It uses Android and has full access to Google Play to expand functionality to include streaming video/music, games, and other apps on its 4.7”, 1280 x 720 display. The unit is 128.9 x 75.9 x 12.7mm x 200g. It uses micro-USB charging.

The player has Wi-Fi, Bluetooth 4.2 aptX, is powered by a Qualcomm Snapdragon 800, and has 32GB storage and dual microSD card slots giving total available storage up 432GBs. ESS technology ES9018K2M x 2 and SABRE 9601K DAC x 2 produces the highest quality audio for High Res audio and existing compressed audio library and streaming sources.

To avoid interference, the unit has two separate motherboards – one for the Android engine and one for the sound engine. It has isolated 2.5mm and 3.5mm audio sockets.

The unit features include (US website)

  • Parts selection and circuit board design were are claimed to be calculated to provide the best signal and bring out the best performance of music with support for playback up to 11.2MHz DSD and 384kHz/24bit WAV and FLAC, and MQA.
  • Incorporates dual ESS Technology’s SABRE DAC “ES9018K2M” paired to SABRE “9601K” amps to create dynamic yet clear sound with good S/N.
  • Balanced output with two forms of balanced drive available. Along with standard BTL balance output, Active Control GND allows the two DAC outputs to work in tandem for L-GND/R-GND “0V” lock to eliminate distortion.
  • Separated DAC/AMP circuit board and Android CPU circuit board, to limit digital noise from affecting the audio circuitry.
  • Consideration against noise by positioning the switching circuitry and analogue circuits as far away as possible within, and placing the analogue circuits as close to the headphone jacks.
  • Fast Qualcomm Snapdragon 800 CPU.
  • Club Sound Boost using balanced output in the EQ settings (audio sources will get mixed to 48kHz).
  • Balanced output, digital output through Micro USB/OTG support allows for output via the headphone jack and peripheral connections.

  • High-quality audio via wireless inc  aptX support for Bluetooth and  Wi-Fi, Wi-Fi Direct.
  • Access to Google Play opens up the XDP-300R’s capabilities beyond what’s built in, by adding apps for streaming music, video, and games.
  • Playback support for “MQA”, the end-to-end technology that captures and delivers master quality audio in a file that is small enough to stream or download, fully authenticated.
  • Support for up to 432GB (32GB internal + dual microSD).
  • Direct download of music from OnkyoMusic service without the need of a PC.
  • Six built-in sound adjustment (Lock range adjust, digital filter, upsampling, Realtime DSD conversion, High Precision EQ, Club Sound Boost).

WEBINAR event: IT Alerting Best Practices 27 MAY 2PM AEST

LogicMonitor, the cloud-based IT infrastructure monitoring and intelligence platform, is hosting an online event at 2PM on May 27th aimed at educating IT administrators, managers and leaders about IT and network alerts.

This free webinar will share best practices for setting network alerts, negating alert fatigue, optimising an alerting strategy and proactive monitoring.

The event will start at 2pm AEST. Topics will include:

- Setting alert routing and thresholds

- Avoiding alert and email overload

- Learning from missed alerts

- Managing downtime effectively

The webinar will run for approximately one hour. Recordings will be made available to anyone who registers but cannot make the live event.



Security requirements such as confidentiality, integrity and authentication have become mandatory in most industries.

Data encryption methods previously used only by military and intelligence services have become common practice in all data transfer networks across all platforms, in all industries where information is sensitive and vital (financial and government institutions, critical infrastructure, data centres, and service providers).

Get the full details on Layer-1 encryption solutions straight from PacketLight’s optical networks experts.

This white paper titled, “When 1% of the Light Equals 100% of the Information” is a must read for anyone within the fiber optics, cybersecurity or related industry sectors.
