Built for Love of Music
High quality mobile audio should not be outrageously expensive or difficult to use. While there are now many DAPs around to choose from, the DP-S1 delivers the best balance of immersive high-fidelity reproduction and everyday practicality. Lightweight, compact, and ruggedly made, the DP-S1 brings joy to your life with an adaptable and future-focused feature set that makes routine daily activities something to look forward to.

Twin DACs and Amps for Balanced Audio
Twin SABRE DACs (ES9018C2M) and amplifiers (ES9601K) are laid out symmetrically and served by separate capacitors. Connect your headphones via 2.5 mm (3/32˝) 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. Whether used in balanced or unbalanced mode, transparent audio reproduction gives insight and dynamic response you just can’t experience with a smartphone.

Universal Music 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, it can upsample audio to give a smooth, expressive, and detail-rich experience. Use dual-band Wi-Fi® and/or a hotspot to enjoy glitch-free streaming on the move from TIDAL Masters, the world’s first Hi-Res audio streaming service, Deezer and  TuneIn Internet Radio. 

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 home audio system, wireless speaker, or car stereo. Both headphone jacks serve as line outputs, meaning you can access almost half a terabyte of music on virtually any hi-fi.

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. MQA support will be added to the DP-S1 via a future firmware update.

Dual Precision Clocking Mechanisms
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.

Get the Sound You Need
What do you love most about your favorite album? Is it an instrument’s tonal quality, or the player’s unique expression? Whatever aspect gets you going can be enhanced even further by selecting from three filters (Short/Sharp/Slow) or the included 10-band EQ. Osbourne or Oistrakh, you can fine-tune a sound that satisfies.

Designed to Do What You Want
A music player interface should do simple things quickly and clearly: find music when you know what you want; present your collection when you don’t; and offer access to skip, stop, and volume controls instantly. It should look also beautiful, and make online and offline transitioning seamless. This original interface ticks all boxes, looking crisp and bright and responding quickly to commands. Due to the device’s small size, comfortable form, and external controls, you don’t get frustrated on the go.

Control Playback with Your Smartphone
The free Onkyo DapController smartphone app uses Bluetooth low energy to connect smartphone to DAP, so you don’t have to reach for your player on crowded public transport. Keep the DAP in your pocket or bag and use your phone to play/pause, skip, scan, shuffle, and repeat songs. Volume control is also included. The app simplifies entry of Wi-Fi passwords, and supports playlist creation using a keyboard.
Note: Mobile devices require Bluetooth low energy (LE) support. Please check App Store or Google Play™ for device and OS requirements.

* Enabled with future firmware update.
