The high Resolution Portable Player Onkyo with Android

The portable player Onkyo DP-X 1 is now ready to land on the European market. The equipment is of a high standard: the heart of the device is made by the operating system Android 5.1.1, run by a quad-core processor 2.2 GHz Qualcomm Snapdragon 800 operating at and flanked by 2 GB of RAM. The display has a resolution of 1280 x 720 4.7 “with pixels and touchscreen.

Inside is a double ES9018K2M ESS Sabre DAC, while the management is delegated to a headphone amplifierESS9601K. Supported files include substantially all of the main types, from MP3 to Direct Stream Digital (DSD) up to 11.2 MHz, besides WAV and FLAC with sample rates up to 384 kHz/24-bit. It is therefore ensure full compatibility with the high resolution audio.

Playable formats are as follows:

  • Audio: DSD, DSF, DSD-IFF, FLAC, ALAC, WAV, AIFF, Ogg-Vorbis, MP3, AAC, MQA
  • Video: h. 263, h. 264 AVC, MPEG-4 SP, h. HEVC 265, VP8, VP9
  • Images: JPEG, GIF, PNG, BMP, WebP

DP-X 1 is compatible with MQA , a technology developed by Meridian. MQA, which stands for Master Quality Authenticated, is nothing but a new way to deliver high resolution audio sources without burdening on the weight of the files. The result was achieved through the use of the frequencies inaudible to the human ear. Instead of “wasting” this space, with no data relevant to the listening, Meridian chose to include the data that normally would be lost during the making of compressed audio files.

The benefits are numerous: you can create audio files in high resolution 24-bit/96 kHz, with quality, occupying a bandwidth of 1Mbps, clearly inferior to 4-5Mbps normally required. The second point is the compatibility to 360°: files so made do not necessarily require compatible hardware. Who does not have a chip able to decode additional data (those included in the space occupied by the inaudible frequencies) can hear a version of songs in CD quality. If instead you use compatible devices, you also get the decoding of information in addition, with a quality equal to that of the masters made in recording studios. MQA can be used with all types of lossless files in high resolution.

Storage space is 32 GB, with the option of using two microSD slot (each of which supports cards up to 200 GB), to expand capacity up to 432GB. Connectivity includes WiFi and Bluetooth, a Micro USB port, a headphone output and a 2.5 mm jack, on line. The autonomy can reach 16 hours on a single charge. We conclude with dimensions: XDP-100R 75.9 mm x 12.7 mm x 129.0 mm measurement, weighing 203 grams.

DP-X 1 will be available in May with a price tentatively set at 899 Euro.
