Onkyo DP-X1 “the world’s best digital audio player”

DP-X1 front angleThe DP-X1 press release makes no bones about it – “Onkyo has launched the world’s best Hi-Res Digital Audio Player, the DP-X1”

That’s a lofty claim to say the least but Onkyo must be pretty sure of themselves.

As you would expect, it handles all the existing Hi-Res formats you can think of, including MQA.

With the rapid rise in consumers wanting “higher than CD quality” High Resolution Audio (High Res Audio) formats, the availability of multiple streaming audio and video services, and High Res-capable headphones, many users have been looking for ways to enjoy their High Res Audio content everywhere they go.

The DP-X1 is powered by the Android OS, and supports the vast majority of High Res Audio formats, up to DSD 11.2MHz, 384kHz/24bit FLAC/WAV audio files.

The new player embodies Onkyo’s dedication to ‘Pure Sound’ as seen on the headphones I recently reviewed.

DP-X1 LifestyleTo isolate sources of internal noise the Audio and CPU circuits are built on separate boards. The Audio circuit design employs ESS Technology’s SABRE ES9018K2M DAC and SABRE 9601K amp in a dual mono setup (ie: a separate DAC and amp per channel) with a 2.5mm 4 pole jack for fully balanced output with support for normal BTL (balanced transformerless) output as well as Active control GND drive, a first in this product category.

DP-X1 outputsThe DP-X1 has been built for expansion beyond its built in functionality. It includes Wi-Fi and Bluetooth for wireless connectivity to peripherals, two microSD card slots for storage (up to a monstrous 432GB!), and access to Google Play to expand upon the builtin apps. There is, of course, the OnkyoMusic app preloaded so you can grab your High Res Audio files without the need of a PC.

It all reads pretty impressively, I’m sure you’ll agree. But, until I get ears on, I shall await to be amazed.
