The LOXJIE D30 is a newly updated DAC and headphone amplifier for 2024, tailored for audiophiles who prioritize superior sound quality and cutting-edge technology. It utilizes the ESS ES9039Q2M 32-bit stereo audio DAC chip, which enables complete MQA decoding and achieves an impressively low total harmonic distortion plus noise (THD+N) of just 0.00008% (-121 dB). With this advanced chip and sophisticated digital filtering techniques, the LOXJIE D30 excels in converting digital signals to analog with remarkable precision, catering to the expectations of even the most discerning listeners.
The device features wireless connectivity through Bluetooth 5.1, utilizing the Qualcomm aptX HD codec. This enables audio transmission at a resolution of up to 24 bits / 48 kHz and a data rate of up to 576 kbps, delivering sound quality that exceeds that of standard CD formats. Additionally, it offers a maximum signal transmission range of up to 20 meters, enhancing its versatility for various usage scenarios.
The LOXJIE D30 incorporates a third-generation XMOS-based audio processing solution, supporting PCM up to 32 bits / 768 kHz and DSD512. This capability ensures the playback of high-resolution audio files without compromising quality. Furthermore, the device is fitted with a Texas Instruments OPA1612 operational amplifier, known for its low noise and distortion levels, as well as its rapid conversion speed, which aids in producing precise and detailed sound.
Constructed from lightweight yet robust aluminum, the LOXJIE D30’s chassis minimizes vibrations and enhances electromagnetic shielding. This design choice helps preserve sound purity and accuracy, even in environments with external interference. The unit is also equipped with an independent low-noise power supply system, ensuring a stable power source for all components, which contributes to improved clarity of vocals and instruments.
The LOXJIE D30 offers a comprehensive range of inputs and outputs for connecting audio sources, including USB, optical, and coaxial inputs, along with 6.35 mm headphone and RCA outputs for line-level connections. Users can easily switch between output modes using the remote control, ensuring a user-friendly experience.
One of the standout features of this device is its seven selectable PCM filters, which enable users to tailor the sound to their preferences. These filters effectively reduce noise and artifacts during playback, resulting in a clearer and more natural audio experience. Additionally, MQA support allows for the full expansion of encoded files, delivering studio-quality sound with a maximum sampling rate of 352.8 kHz.
The LOXJIE D30 serves as an excellent desktop audio solution for those seeking a versatile DAC that includes a high-quality headphone amplifier, compatibility with modern audio formats, and extensive connectivity options.
