Portable Bluetooth DAC Amp

The Topping DX3 Pro+ is a portable audio device that combines a Bluetooth 5.0 receiver, a high-performance DAC and a dedicated headphone amplifier in a silver chassis. It uses an ES9038Q2M converter and a QCC5125 Bluetooth chip to decode LDAC and other codecs wirelessly. The unit also functions as a pre-amplifier for external systems. It is built for listeners who want wireless and wired high-resolution playback from a single compact box.

Decoding Specifications

The ES9038Q2M DAC delivers a THD+N of 0.00015 % and handles PCM up to 32-bit/768 kHz plus native DSD512 via the XMOS XU208 USB interface. Bluetooth 5.0 with LDAC support enables high-quality wireless streaming. The integrated NFCA headphone amplifier provides 1800 mW per channel into 32 ohms and 250 mW per channel into 300 ohms with an output impedance suited to a wide range of headphones.

Ideal For And Not For

This device suits desktop users who need a single unit for USB and Bluetooth decoding with ample headphone power for both low and high-impedance models. It is not for buyers who require balanced headphone outputs or multi-channel surround decoding. It also does not fit users looking for a battery-powered portable player or a unit with integrated streaming services.
