Pairing the FiiO X3ii digital audio player with the FiiO Q1 headphone amplifier/digital analogue converter is an elegant way to cover all of your high resolution audio needs. The X5ii takes all the successes associated with FiiO (quality, sound presentation, value for money) and turns it up to 11, creating a sonically beautiful DAP for an incredibly reasonable price. The Q1 is a new addition to the FiiO family that builds on the technical successes of the E07K DAC/Amplifier and refines them into a powerfully versatile unit. Together they provide both the power and the audio presentation needed to make your high resolution, lossless music files sing! 

The FiiO X5ii (Second Generation) breaks new ground in affordable, portable, digital music players. FiiO has completely re-worked the audio architecture utilising a JZ4760B + SA2000 + PCM1792A + PGA 2311A sequence of audio chips. This allows native decoding of DSD64/128 files alongside other lossless formats at 192kHz/24 bit (WAV, FLAC, APE, WMA, ALAC, AIFF etc.). These files are then realised using top of the range Texas Instruments OPA1652, OPA1612 and BUF634U chips to maintain ultra-low distortion levels (0.000015%) and supplying up to a 250mA current output (which is a 67% improvement on the previous model). This new model also includes dual crystal oscillators – one dedicated to multiples of 44.1 kHz, the other to multiples of 48 kHz – to improve the accuracy of audio replication by 25 times whilst diminishing jitter. 

The FiiO Q1 is an elegantly designed unit can function both as a portable amplifier for your audio player as well as a USB DAC for your computer, easily slipping into whichever role it needs to fulfil. A premium Texas Instruments PCM5102 DAC chip gives the Q1 a high S/N ratio and low distortion, excellent dynamic performance and enhanced jitter rejection. The plug and play nature of the Q1 makes it ideal as an effective USB upgrade of your computer’s on-board sound card and supports sample rates if up to 96kHz/24bit. Portable audio units can connect by using a simple 3.5mm jack line-in connection (which doubles as a line out should a USB audio source be in use).
