iBasso DC07PRO Portable Hi-Res USB DAC and Amp (Silver)

The iBasso DC07PRO is a portable, high-resolution USB DAC and amplifier designed to elevate your mobile audio experience. This compact device utilizes four Cirrus Logic CS43131 DAC chips, enabling it to process high-fidelity audio up to 32-bit / 768 kHz PCM and native DSD512. It features both 3.5mm single-ended and Pentacomm 4.4mm balanced headphone outputs, providing versatile connectivity for a wide range of headphones. The DC07PRO boasts amplification up to 430+430mW at 32 Ohms, ensuring it can drive demanding headphones with ease.

An integrated 0.96" OLED display and multifunction knob offer intuitive control over volume, settings, and playback. The device is engineered for an ultralow noise floor, delivering a clean and immersive listening experience. Its portable design makes it an ideal companion for audiophiles on the go.

The DCO7PRO leverages iBasso's proprietary FPGA technology, a core component that integrates audio algorithms and manages the system. This FPGA serves a critical role in signal regeneration and precise clock synchronization. Furthermore, it generates ultralow-jitter clocks for both the DAC and USB receiver, effectively minimizing clock jitter introduced by the USB bus.

At the heart of the DCO7PRO's audio performance lies a powerful array of four Cirrus Logic CS43131 flagship DAC chips. Combined with iBasso's unique FPGA implementation and meticulously designed circuitry, this configuration achieves exceptional audio specs.

Notably, the measured THD+N reaches an impressive -120.2 dB. The FPGA enables the DCO7PRO to support high-resolution audio formats, including native DSD512 and PCM up to 32-bit / 768 kHz, representing a significant advancement in quad-DAC technology.

Optimized Power Efficiency

The DCO7PRO prioritizes power efficiency without compromising power output. A synchronous DC-DC converter, boasting a 94% power conversion efficiency, ensures minimal power consumption. At only 80mA, the DCO7PRO consumes 40% less power than the DCO4PRO, while delivering an 82% increase in output power.

The DAC's power supply utilizes ultralow-noise LDOs designed for analog circuits, achieving a power-supply rejection ratio (PSRR) of up to 100 dB, guaranteeing a clean and stable power source for pristine audio reproduction.

The DCO7PRO features a user-friendly interface centered around a 0.96" OLED screen and an ALPS encoder knob. This combination allows for seamless navigation and adjustment of all settings.

Users can effortlessly control volume, digital filter settings, and other parameters by simply rotating and pressing the multifunction knob. Additionally, the DCO7PRO supports the iBasso UAC Android APK, providing convenient control via Android devices.

Premium Design and Construction

The DCO7PRO's design reflects its high-end audio aspirations. The device boasts a CNC-machined aluminum shell, an OLED screen integrated into the top surface, and a tempered-glass back cover.

A strategically placed side knob enhances both functionality and aesthetics. The overall design exudes a luxurious and sophisticated feel, reminiscent of premium digital audio players.

Addressing the power limitations of iPhone devices, the DCO7PRO's low 80mA power consumption ensures compatibility without triggering power protection shutdowns. The multifunction knob and OLED screen enable quick and easy adjustments of gain and filters, eliminating the need for an APK on iOS. Users can fully utilize the DCO7PRO's features with their iPhones.

Versatile S/PDIF Output

Expanding its versatility, the DCO7PRO supports S/PDIF output up to 32-bit / 768 kHz, transforming a smartphone into a high-resolution S/PDIF source.
