Manufacturer's Description

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 192 kHz/ 24 bit. To avoid interpolating the DSD signal for volume control, FiiO added Texas Instruments' best analog volume controller PGA2311A, ensuring the most faithful reproduction of DSD while avoiding issues with know 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 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 (1.1 nV/√Hz). 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 44.1 kHz (44.1 / 88.2 / 176.4 kHz, DSD64/128) and 48 kHz (48 / 96 / 192 kHz) respectively. Moreover, it employs the SiTime MEMS oscillator made in the USA; compared to traditional quartz oscillators, it has a wider working temperature range and jitter within 1ps, imporving 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, FiiO 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. FiiO's engineers packed the above-mentioned more advanced and complex circuitry into a 15% lighter, 12% smaller package than the X5 1st 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.
