![]() This result in improved sound quality and better overall performance of the device, and also gives 90 more minutes of battery life compared to running under Android 4.4 To circumvent the rpoblem of third-party Android apps automatically converting the sample rate of music, FiiO's software team wrote an entire new audio software architecture for its deeply customized and optimized version of the Android 5.1 OS. This allows the new X5 to cater to fans of either headphones output type.ĭeeply customized Android 5.1 OS for efficient music playback The X5 3rd gen has two headphones outputs - one single-ended and the other balanced. The outstanding sound quality of the final audio architecture employed in the X5 3rd generation is the result of closed beta users working tirelessly together with the team at FiiO in a quest to make this new X5 sound the best that it can. ![]() The X5 3rd gen utilizes two dual-channel OPA1642 chips for its low-pass filtering stage and a custom-made audiophile-grado OPA426 chip for amplification, providing greater power output (up to 300mW under a 32 Ohm load) and greater ability to deal with capacitive loads. This ensures that under all sampling rates, there is significantly reduced jitter, improved clock accuracy, more stable operation, and virtually no sampling rate conversion artifacts.įour-way LPF for first-rate amplification The X5 3rd gen utilizes two separate crystal oscillators, one for the DSD/44.1/88.2/176.4/352.8kHz sampling rates and the other for 48/96/192/384kHz. By using a dual-channel implementations of AKM's unique VELVET SOUND low-distortion architecture that includes digital filtering with 32-bit processing, the DAC chips in the C5 3rd generation have the ability to finely and exactly reproduce your music.ĭual crystal oscillators for faithfully reproduced music The AK4490EN is a part of a new generation of high-quality 32-bit DACs that supports all PCM and DSD formats. The X5 3rd gen is equipped with two top-of-the-line AKM AK4490EN DACs, one for each channel. ![]() The new generation X5 was just released to the public at Fiio 2016 Winter Launch Event. ![]()
