Fiio X5 Gen2

簡介 / Description

Good sound comes from a quality power sipply
To improve sind quality, the all-new x5 employs seamless voltage switching between different gain levels. At high gain, the working voltage reaches 14V (+-7V), 40%higher than the 1st gen x5, pitting the opamps in their best working voltage, greatly increasing dynamics. At low gain, the working voltage is adjusted to +-5V, reducing power consumption, increasing runtime.

特性 / Feature

• Native DSD128 decoding
  The all-new X5 utilizes on all-new digital audio architecture Praesto Personal AudioJZ4760B+SA2000+PCM1792A+Pga2311A, and is able to decode native DSD64/128, and directly play SACD ISOs. Other lossless formats such as (WAV, FLAC, APE, WMA, ALAC, AIFF, etc). are also supported at up to 192 kHz/24 bit. To avoid interpolating the DSD aignal for volume control, we added Texas Instrments’Beat analog volume controller PGA2311A, ensuring the most faithful reproduction of DSD while avoiding issues with knob potentiometers such as channel imbalance and poor durability.
• Only the best parts
  Synetgistic combination of flagship components
  The all-new X5 preserves the top-flight PCM1792A from Texas Instruments, coupled with the new OPA1652 with great dynamic performance and FET inputs for I/V conversion, realizing extra-low distortion (0.00005%) and noise. Also utilizing two top-flight OPA1612 for lowpass filtering and voltage amplification for extra-low distortion (0.000015%) and noise (1.1nV/XXX). Finally to attain sufficient driving current for wide sound stage, highly-dynamic musical performance, and good bass power, the headphone output stage emplous two BUF634U for current buffering, supplying up to 250mA current output(67% improvement over X5 1st gen).
• Dual crystal oscillators supplying the most precise timing
  Timing – the basis of digital audio
  The all-new X5 employs two silicon crystal oscillators, handing multiples of 44.1kHz (44.1/88.2/176.4kHz, DSD64/128) and 48kHz (48/96/192kHz) respectively. Moreover, it employs the SiTime MEMS Oscillator made in USA; compared to traditional qurtz oscillators, it has a wider working temperature range and jitter within 1ps, improving accuracy by 25 times..
• From “off” to on in 0 seconds flat
  Deep-sleep standby for instant-on music in everyday use
  On the basis of the X5, we applies the newest technology from the likes of smartphone onto the all-new X5. Through the engineers efforts, the all-new X5 Successfully reduced standby power consumption to <5mA, so that it may remain in standby for about 4 weeks from a full battery.
• Dual micro SD card slots
  Supporting up to 256GB (128GBx2)
