About: FiiO X3II (2nd Gen) Portable High Resolution Audio Player - Black

After years of research and development, FiiO has developed a hi-definition portable player that supports all major lossless audio codecs at up to 192k/24b master tape quality, allowing those who love music and love it in high fidelity to find the sound they have been missing at long last. Further, there is added support for HE-AAC, MP3 CUE and 32bit/64bit/floating point music tracks. This makes its format compatibility the most complete among hi-end portable music players. With the X3 2nd gen, music lovers worldwide need not worry about music format compatibility or format conversions anymore. Even Apple's proprietary ALAC lossless codec is decoded flawlessly on the X3 2nd gen.

Dual Crystal Oscillators:

Dual crystal oscillators to multiples of 44.1 and 48kHz respectively, ensuring that the X3 2nd gen has the lowest jitter and highest precision for playback of music at all sample rates and eliminating all conversion artifacts.

Audiophile-Grade Architecture and Components:

Utilizing Cirrus Logic's top-flight CS4398 DAC coupled with FiiO's low-pass filter, the X3 2nd gen realizes extremely low noise and phase distortion. Further the X3 2nd gen utilizes premium tantalum capacitors in the analog circuit for minimum internal resistance for the best undistorted sound.
