Music Like You’ve Never Heard It Before

The DP-S1 condenses blue-chip DAP performance into a palm-sized package with a form factor to fit daily life and performance to transport you from train carriage to another world. Twin SABRE® DACs and amps, dual clocks, balanced and unbalanced outputs, Wi-Fi®, Bluetooth®, and monster storage capability coalesce behind a touch interface you can navigate with one hand. Treating Hi-Res Audio signals with finesse, the player gives detailed insight on songs you thought you knew backwards, inspiring a new appreciation for old favorites. Even compressed files stretch out and breathe on a 3D soundstage, each instrument clearly defined, every note guided with precision. Push up the volume as far as you like without clipping. Built for the audiophile inside us all, the DP-S1 is an investment that rewards with sonic satisfaction. Just press play.

Built for Love of Music Image

Built for Love of Music

The compact, lightweight DP-S1 delivers the best balance of immersive high-fidelity reproduction and everyday practicality, with line outputs, Wi-Fi®, and Bluetooth® extending the scope of application beyond that of headphones and into that of a premium standalone audio player and DAC for car and home stereos. This player brings joy to daily life with an adaptable, future-focused feature set that makes routine activities events to look forward to.

Twin DACs and Amps for Balanced Audio Image

Twin DACs and Amps for Balanced Audio

Twin ESS SABRE® DACs (ES9018C2M) and amplifiers (ES9601K) are laid out symmetrically and served by separate capacitors. Connect your headphones via 2.5 mm 4-pole output to enable Balanced Audio Output with both DACs and amps employed simultaneously. Two modes are available: BTL, to increase driving power, and ACG mode for enhanced stability. Both modes offer a tangible increase in headroom and spatial dimensionality. Transparent reproduction gives insight and dynamic response you just can’t experience with a smartphone.

Universal Format Support Image

Universal Format Support

The DP-S1 supports MQA*, DSD 5.6 MHz/2.8 MHz, FLAC, WAV, ALAC, and AIFF up to 192 kHz/32-bit*, and plays all popular compressed audio formats. For lower quality files, upsample audio to 192 kHz/24-bit for a smooth, fluent, and detail-rich experience. Use dual-band Wi-Fi® to get glitch-free lossless streaming from TIDAL wherever you are, enjoy TuneIn internet radio, and look forward to more leading services to follow via firmware update.

* Enabled with future firmware update. Native 32-bit audio downsampled to 24-bit on playback.

Connect, Stream, and Cast Image

Connect, Stream, and Cast

Dual-band 5 GHz/2.4 GHz Wi-Fi® supports streaming from on-demand music services. Bluetooth® wireless technology lets you mirror content from DAP to a wireless speaker or car stereo system. Analog and digital audio outputs connect you up to integrated amps and home stereos, meaning you can access half a terabyte of music, network streaming, and more on virtually any audio system.

Control Playback with Your Smartphone Image

Control Playback with Your Smartphone

Onkyo DapController app for iPhone, iPod touch, and Android™ devices employs Bluetooth Low Energy to connect smartphone to DAP, so you don’t have to reach for your player on crowded public transport. Keep the player in your pocket or bag and use your phone to play/pause, skip, and adjust volume.

Note: Mobile devices require Bluetooth Low Energy (LE) support. Please check App Store or Google Play for device and iOS requirements.

Supports MQA*, Tomorrows Hi-Res Format Image

Supports MQA*, Tomorrow’s Hi-Res Format

MQA is not typical Hi-Res Audio with a higher bit rate or higher sampling rate. 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.

* Enabled with future firmware update.

Dual Precision Clocks Image

Dual Precision Clocks

Between source and headphone driver, every detail counts when it comes to reproducing music as it was captured, mixed, and mastered. That’s why we include independent clocks for native 44.1 kHz and 48 kHz signals. High-precision clocking significantly reduces jitter (glitches, pops, and noise artifacts) that can arise if data transmission is not timed to perfection. Further, dual clocks allow Hi-bit Upsampling to adapt for best results.

A Touch Interface That Works Image

A Touch Interface That Works

A music player interface should do things quickly and clearly: find music when you know what you want; present your collection to browse when you don’t; and offer easy access to controls. It should look beautiful. This original touch interface ticks all boxes, looking crisp and bright and responding quickly to gestures.

Massive Storage Capacity

Shipping with 16 GB of onboard memory, the DP-S1 has two microSD Card slots that expand storage to a whopping 512 GB with two 256 GB cards (purchased separately). You’re essentially carrying a portable HDD in your pocket. Better still, you can simply drag-and-drop your album folders onto the cards from PC, and pop the cards back to the DAP when you’re done.

EQ Your Way to Sonic Satisfaction

What do you love most about your favorite album? An instrument’s tonal quality, the player’s unique expression? Whatever aspect gets you going can be enhanced even more by selecting from three filters (Short/Sharp/Slow) or by using the 10-band EQ. Bump the bass, tone down the cymbals, tune overall levels to suit a style of music, then name and save for later recall.
