Bundle Includes FiiO X5-II High Resolution Lossless Music Player - Black Ultimate Ears UE 900S Universal Fit Earphones Good sound comes from a quality power supply Seamless voltage switching design between different gain levels. High gain reaches 14V (+/-7V), 40% higher than the 1st gen X5, putting the op amps in their best working range, greatly increasing dynamics. Low gain voltage adjusted to +/-5V, reducing power consumption for increased runtime. Native DSD128 Decoding All new digital audio architecture: JZ4760B + SA2000 + PCM1792A + PGA2311A. Native DSD64/128 support and SACD ISOs. Other lossless formats such as WAV, FLAC, APE, WMA, ALAC, AIFF are also supported at up to 192kHz/24bit. Usage of Texas Instruments best analog volume controller ensures most faithful reproduction while avoiding issues such as channel imbalance. Only the Best Parts Top shelf PCM1792A from Texas Instrument coupled with new OPA1652 gives great dynamic performance and FET inputs for I/V conversion, realizing extra-low distortion (0.00005%) and noise. Two OPA1612 are used for low pass filtering and voltage amplification. Finally, two BUF643U current buffers supply up to 250mA output to headphones, achieving wide sound stage and highly dynamic musical performance with good bass power. Dual Crystal Oscillators The X5-II makes use of two crystal oscillators, one each for the 44.1kHz and 48kHz frequency multiples. This no-compromise design ensures the lowest jitter and highest precision for playback...
