FiiO  X5 2nd gen High Resolution Lossless Native DSD Decoding 192kHz/24bit HiFi Music Player


  • One small step in your eyes , one giant leap in your ears.
  • All new X5 2nd gen-native DSD decoding, more musical, more portable.

Good sound comes from a quality power supply

  • To improve sound 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, putting 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.

Native DSD128 decoding

  • Discrete analog volume control, SACD ISO direct decoding.The all-new X5 utilizes an all-new digital audio architecture JZ4760B+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 192KHZ/24BIT.To avoid interpolating the DSD signal for volune control, we added Texas Instruments’best 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

  • Synergistic combination of flagship components
  • The all-new X5 preserves the top-flight PCM1792A from Texas Instruments, coupled with new OPA1652, with great dynamic performance and FET inputs for I/V conversion, realizing extra-low distortion 0.00005%) and noise.
  • Also utilize two top-flight OPA1612 for low pass filtering and amplification for extra-low distortion (0.000015%) and noise.
  • Finally, to attain sufficient driving current for wide sound stage, highly-dynamic musical performance, and good bass power, the headphone output stage employs 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, handling 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 quartz oscillators, it has a wider working temperature range and jitter within 1ps, improving accuracy by 25 times.

From “off” to on in 0Seconds flat

  • Deep-sleep standby for instant-on music in everyday use
  • On the basis of the X5, we applied the newest technology from the likes of smartphones 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.

Lighter, smaller, more ergonomic

  • As a portable product, “portability” is always an important criterion to strive for. Through our engineers ' efforts, we packed the above-mentioned more advanced and complex circuitry into a 15% lighter, 12% smaller than the X5 lst gen.
  • To further benefit portable usage, the all-new X5 also supports headsets with CTIA-standard in-line remotes, allowing operations such as play/pause, skip, fast forward and rewind to be controlled remotely.
  • The all-new X5 also inherits various helpful design touches that we learned from Previous models, such as the 3 closely spaced but unique side control buttons- recessed Power button, raised volume + button with tactile dot , and raised volume -button without tactile dot together allow speedy unsighted control without risk of mis-press. The status LED has been moved to the side to avoid glare in usage. Various control Schemes allow flexible control of the player even while the screen is off.
  • The all-new X5 also supports 10-EQ and user-defined playlist (.m3u/m3u8), and can switch between 5 different display themes on the same firmware.
