TOPPING DX3 Pro+ Bluetooth Desktop DAC & Headphone Amplifier

Introducing the TOPPING DX3 Pro+ DAC/Amp, an evolution of the classic DX3 Pro, now with upgraded features and an even more affordable price point.

Enhanced Performance: The DX3 Pro+ boasts substantial improvements over its predecessor. With a new Bluetooth chip and DAC chip, it achieves remarkable results: 60% lower THD+N (DAC), 85% lower THD+N (HPA), over 100% more power, and 90% lower output impedance compared to the DX3 Pro (LDAC version).

Bluetooth 5.0 LDAC: Featuring Bluetooth 5.0 LDAC support powered by a Qualcomm QCC5152 chip, the DX3 Pro+ delivers Hi-Res Audio Wireless. Notably, it deploys the ESS ES9038Q2M chip for Bluetooth codec decoding, ensuring exceptional performance.

Plug-and-Play Convenience: Enjoy the benefits of a high-end DAC by simply connecting the DX3 Pro+ via USB to your PC or Mac, with no need for drivers. Only higher-end ASIO applications on Windows 10 require a driver.

Low-Noise NFCA Circuit: The DX3 Pro+ is equipped with an optimized NFCA circuit that provides robust, distortion-free performance, delivering 1800mWx2 @32Ω and an impressive 0.00015% THD+N.

Versatile Gain Settings: Tailor your audio experience with ease using the DX3 Pro+'s two gain settings (+6dB/+19dB), accommodating a wide range of headphone impedances, from IEMs to full-sized headphones.

Four Output Modes: Adapt to every listening scenario with the DX3 Pro+'s versatile output modes: headphone amp, headphone amp + DAC, DAC, and preamplifier.

Bluetooth Amplification and Receiver: Connect your phone, iPad, or laptop to the DX3 Pro+ via Bluetooth to enjoy high-quality music through headphones or use it as a premium Bluetooth receiver by connecting its RCA output.

Universal Compatibility: The DX3 Pro+'s USB input is compatible with both Android and iOS devices, elevating your audio experience whether you're using a phone or tablet. Android devices require OTG USB sound card support, while iOS devices need a special DAC cable or camera kit connection.

DAC and Preamplifier Functionality: When you require the DX3 Pro+ to work alongside an amplifier or active speakers, set its output mode to preamplifier. This allows you to decode audio and adjust volume conveniently, with the added convenience of a remote control.

Simplified DAC Mode: In situations where you only need a straightforward DAC, the DX3 Pro+'s output mode can be set to DAC. The screen displays the current sampling rate, and it consistently outputs 2Vrms for optimum performance.

The TOPPING DX3 Pro+ DAC/Amp represents the evolution of a classic, offering a significant performance boost at a more accessible price point compared to its predecessor. With enhanced features like Bluetooth 5.0 LDAC support, low-noise NFCA circuitry, versatile gain settings, and four output modes, it caters to audiophiles seeking a superior audio experience. Whether you're connecting via USB, enjoying wireless Hi-Res Audio, or transforming it into a preamplifier, the DX3 Pro+ delivers exceptional sound quality and adaptability. Upgrade your audio setup today and discover the next level of sonic excellence with the DX3 Pro+.
