Specifications and Performance
Equipped with dual 32-bit 2-channel ES9039Q2M DAC chips, the DX5 II delivers impressive performance for balanced headphones, achieving a signal-to-noise ratio (SNR) of 133 dB and a dynamic range of 133 dB. The total harmonic distortion plus noise (THD+N) at 1 kHz (A-weighted) is less than 0.00006%. The X-Hybrid amplifier is capable of driving low-impedance headphones at 7600 mW for 16 Ω and can also handle high-impedance headphones up to 490 mW at 600 Ω, all while maintaining THD+N below 1%. For added convenience, you can connect external active speakers directly to the DX5 II in preamp mode.
Wireless and Connectivity Features
The DX5 II also shines when it comes to wireless capabilities, featuring a Qualcomm QCC5125 Bluetooth 5.1 System on Chip (SoC). It supports a variety of codecs for Bluetooth audio, including standard SBC and AAC, as well as higher-quality aptX Adaptive, aptX HD (24-bit, 48 kHz at 576 kbps), and High-Res Audio LDAC (24-bit, 96 kHz at 990 kbps).
For direct connectivity, the DAC can be linked to PCs via USB, allowing playback from streaming platforms and local music files, supporting formats like 32-bit 768 kHz PCM and DSD512. It can also operate in ASIO mode using the Thesycon driver, which is great for low-latency professional audio tasks. The 12-volt input/output trigger allows for automation when paired with other audio devices.
Customization and User Interface
Users can fine-tune their audio experience with the 10-band parametric EQ software for PCs, enabling the saving and recalling of multiple custom profiles. The 2.0-inch LCD display provides easy access to all settings and status information, which can be navigated using the input knob and three control buttons.
