Features

High-Quality Components: The Onkyo DP-X1 hi-res portable digital audio player delivers exceptional sound quality thanks to its dual ESS Sabre DACs & amps, symmetrical twin DAC & circuit design, noise isolating circuitry, and closed loop configuration. Your digital music library will sound the way the artist intended.

• Dual ESS Sabre DACs & Amps: Two ESS Technology Sabre ES9018K2M 32-bit/192kHz DACs and two Sabre 9601K amps allow for extraordinary power and control from a portable device. The double ESS Sabre ES9018K2M DACs and double ESS Sabre 9601K amps make balanced output possible via a 2.5mm output.
• Symmetrical Twin DAC & Circuit Design: Optimal component placement of the twin DACs and amps for symmetric circuit design (short, equal distance) yields greater control over balanced signals.
• Noise Isolating Circuit Design: Similar to the build used in audio receivers, the DAC & amp board is separated from the CPU board to minimize noise and maximize performance. Within the DAC & amp board, the audio circuitry and switching power are also separated to reduce noise.
• Closed Loop Design: The DACs & amps have their own capacitors to provide a clean audio signal with closed loop design that improves audio signal quality for all audio formats.

Two Types Of Balanced Drives (BTL & ACG): Balanced output via the 2.5mm 4-pole jack supports the more standard balanced (BTL) drive as well as the more esoteric Active Control Ground (ACG) drive. ACG drive is a different form of balanced drive where the amp's cold side actively drives to create an ideally stable GND. Power gains and increased sound separation increase stability for a clean signal and greater sound clarity, especially compared to unbalanced drive.

• BTL (Balanced): The BTL drive supplies increased power. Power gains and increased sound separation associated with balanced output are repurposed to create increased stability for a clean signal and greater sound clarity, especially compared to unbalanced drive.
• ACG (Active Control Ground): The ACG drive gives greater stability with increased S/N ratio, greater spatial dimensionality, and clean sound; plus greater delineation for lower frequencies in hi-res audio; and overall robust sound. 

Android OS & Google Play: The Onkyo DP-X1 utilizes a super flexible and intuitive Android (5.1.1) operating system & user interface, plus a fast quad-core 2.2GHz CPU and 2GB RAM with support for powerful digital signal processing (DSP) and the latest Android compatible applications. And because the DP-X1 is based on the Android platform, it also supports the Google Play Store. From The Google Play Store you have access to many apps like Tidal, Spotify, & Pandora for almost endless music streaming and downloading resources.

Touchscreen & Physical Buttons: The Onkyo DP-X1 features a 4.7" (1280 x 720) capacitive touchscreen display for control, song/artist info, and album art. The capacitive touchscreen display allows for intuitive use of flicks, taps and scrolling gestures that smartphone users are already accustomed to. All touchscreen icons, physical buttons and knobs are positioned with one handed operation in mind. Playback control in the music player supports flick gestures for track advancing, and tapping the progress circle allows for direct control of track positioning. Physical buttons offer quick music control with no need to turn on the touchscreen display.

Built-In & External Storage: With 32GB of internal storage and dual microSD card slots, storage can be expanded to 432GB. Each microSD card slot will support SD, SDHC, and SDXC memory cards up to 200GB. No microSD/SDHC/SDXC memory card is included (all sold separately).

Hi-Res Audio: The Onkyo DP-X1 was designed to support many audio formats, including compressed, lossless, and hi-res audio. Maxing out at 11.2MHz DSD support, the DP-X1 also supports up to 384kHz/24-bit audio, with support for WAV, FLAC, ALAC, & AIFF.

• Supported Audio Formats: DSD (DSF/DSDIFF), FLAC, ALAC, WAV, AIFF, Ogg-Vorbis, MP3, AAC, & MQA (via free update)
• Sampling Frequencies & Bit-Rates: 44.1/48/88.2/96/176.4/192/352.8/384 kHz (16 bit/24/32-bit), 2.8/5.6/11.2 MHz (1-bit)

MQA Compatible: MQA is not typical hi-res, a high bit-rate or high sample rate audio. It is a completely new and different way of capturing, delivering and reproducing audio performances, and it preserves the magic of the original studio recording in a format that is still small enough to stream

Upsampling & Conversion: The Onkyo DP-X1 has the ability to upsample & upconvert your digital music library to make it sound even better through its microUSB-B/OTG digital output (not analog output).

• Hi-Res Upsampling: The DP-X1 upsamples 44.1k, 48k, 88.2k, 96k, 176.4k, and 192k music files up to 352.8/384kHz through its microUSB-B/OTG digital output (not analog output). Enjoy all your digital music content upsampled to Hi-Res audio quality.
• DSD Conversion: Turn on "Real-Time DSD Conversion" and the DP-X1 converts music files such as MP3, WAV, and FLAC into DSD-quality audio through its microUSB-B/OTG digital output (not analog output). Use of oversampling and pushing bit quantization outside the audible spectrum allows for very clear audio signals. 44.1k, 48k, 88.2k, 96k, 176.4k, 192k, 352.8k, and 384k music files can be converted to DSD 2.8/5.6Mhz.

X-DAP Link: Manage and transfer your non-DRM protected music on your Windows or Mac computer to the Onkyo DP-X1's built-in memory or insert microSD card (not included) using X-DAP Link. The DP-X1 will connect to your computer via the included microUSB-to-USB cable. X-DAP Link searches your music libraries, including music purchased from other services, and transfers the song and related metadata to the selected storage location on the DP-X1.

Onkyo Music: The OnkyoMusic download service offers the latest music releases and remastered albums in hi-res for beyond-CD quality audio. Install the OnkyoMusic app and there is no need to sync with a home computer. Music can be purchased and downloaded directly from the app within the DP-X1 portable digital audio player.

Fine Tuning Controls: The Onkyo DP-X1 provides a variety of audio controls to fine tune your music for the ultimate listening experience.

• High Precision EQ: With up to 16,384 discrete bands to select from and the ability to save up to 1,000 EQ profiles, the linear-phase finite impulse response (FIR) equalizer offers high definition equalization with zero loss in audio quality.
• Sound Presets: Experience sound presets created by professional musicians.
• Digital Filters: By modifying the filter characteristics of the built-in digital converter you can modify the audio sound quality for output to headphones. Sharp, Slow, & Short digital filters adjust sound characteristics on the fly. The Sharp mode improves linear startup of sound, bringing the sound forward. The Slow mode improves response, particularly for stringed instruments, allowing for softer resonance and natural sound. The Short mode keeps the sound characteristic neutral.
• Lock Range: You can improve sound quality by adjusting the lock range of the audio input signal's jitter (modulation). Adjust the 7-position lock range to limit jitter noise, improving S/N ratio. Narrowing the lock range will dampen jitter noise's effect on sound.
• Stand Alone Mode: In Stand Alone Mode, Wi-Fi, Bluetooth and the touchscreen display, which are sources that can create digital noise, are turned off. During Stand Alone Mode, use the physical volume knob and playback buttons to control your music.

Wired & Wireless Connectivity: With its 2.5mm/4-pole balanced output, 3.5mm/3-pole headphone jack, micro USB-B/OTG digital output, and wireless playback options, the DP-X1 offers plenty of ways to enjoy music.

• Balanced & Unbalanced Analog Outputs: The Onkyo DP-X1 is fitted with a 2.5mm/4-pole balanced output (32-600Ω) and 3.5mm/3-pole headphone jack (16-300Ω) for connecting a set of headphones or external audio equipment.
• microUSB-B/OTG Digital Port: The DP-X1's microUSB port lets you connect a headphone amplifier or D/A converter, that has a USB connector. You will need a USB OTG cable (sold separately) to connect to this unit. Make sure you have the correct type of USB cable for the USB port of the device you are connecting to the OTG cable. If it is a microUSB port, you can use the USB cable included with this unit.
