The titanium X3 (2nd Gen) from Fiio is a portable high resolution audio player and USB-DAC for audio enthusiasts. The unit features an audiophile grade architecture and premium components capable of playing files up to 24-bit/192 kHz in a variety of formats including native DSD, WAV, WMA, ALAC, FLAC, APE, AIFF, and more. The X3-II utilizes a Cirrus Logic CS4398 DAC coupled to a finely tuned low-pass filter offering extremely low noise and phase distortion. Additionally, the tantalum capacitors in the analog circuit provide minimal internal resistance for the best uncolored sound. Dual crystal oscillators ensure the lowest jitter and highest precision playback of music at any sample rate, eliminating conversion artifacts.
The player offers a standard 1/8" / 3.5mm headphone output and a separate line out/digital (coaxial) out via 1/8" / 3.5 mm. The X3II has no on-board memory, but uses a microSD card slot supporting up to 128 GB. The 2600 mAh Li-polymer battery provides up to 11 hours of playback under normal conditions. The user interface (UI) offers six unique themes, while the classic scroll wheel and 2.0" TFT display offer easy navigation, which supports browsing and playback via folders, songs, albums, artists, genres, favorites, and playlists. The 10-band graphic EQ and the 120-step digital volume control allow for custom tailored sound and levels.
The chassis is made of aluminum alloy and features a high reflectance fine-grain faceplate. The X3-II ships with a 3' / 1m high-current micro-USB data/charging cable, an 1/8" / 3.5mm coaxial S/PDIF adapter, a hard-shell case, two screen protectors (1 applied in-factory), and a set of three Bodywork stickers (USA flag, wood grain, and carbon fiber).
