The XDUOO XD05 Bal2 is an amplifying auricle of superlative quality. Its individually crafted designs showcase the puissant strengths and distinct persona of the XD05 product series. Furnished with dual power modalities and abundant energy, the XD05 Bal2 is indisputably a formidable Headphone Amplifier. Employing a dual DAC chip configuration, the XD05 Bal2 processes digital audio signals simultaneously, irrespective of device type or format, from smartphones and tablets to computers, and from MP3 to DSD. This capability unveils an exceptional wealth of musical intricacies. With a THD+N diminished to a mere 0.00065%, the integration of two original low-phase noise crystal oscillators and a novel CPLD drastically mitigates clock jitter. Its output power reaches 1500mW, which makes the diaphragm of the earphone vibrate fully and improves the loudness of the harmonics. Even high-impedance, 300-ohm headphones reveal an extraordinary degree of musical detail, clarity, dynamism, and elasticity, allowing listeners to bask in the delight engendered by music. The AES balanced input and 4.4mm balanced output create a seamless circuit from digital input to the headphone output, affording balanced headphones heightened crosstalk and an expansive soundstage for a novel auditory experience. If the bass of your headphone is weak, you can get an excellent bass feeling by turning on the bass and increasing the low frequency of the headphone. XDUOO has ingeniously engineered the device for effortless op-amp chip installation, enabling users to swap various op-amp chip models at will and discern the distinct audio quality each chip imparts. Moreover, the XD05 Bal2 incorporates Bluetooth 5.1 technology, supporting high-definition formats such as aptX_HD and LDAC. A built-in 5000mAh lithium-ion polymer battery ensures continuous playback for over 12 hours. When indoors, the device can harness external power (EXTE gear) to conserve battery life, ensuring a fully charged internal battery when portability is required. The XD05 Bal2 features a sleek, compact screen design; the OLED display clearly shows the audio sampling rate, input interface, power ,and DAC filter status.
