Rohde&Schwarz UPV – the world's most advanced audio analyser – and used in all tests here.

 

 

MEASURED PERFORMANCE

Frequency response of the FiiO X1 2nd Gen measured flat to 52kHz (-1dB) with a 192kHz sample rate digital signal, so it has plenty of analogue bandwidth, and it is flat across the audio band as our analysis below shows.

   Output measured 1.5V, more than enough to drive even insensitive headphones loud. Line output was identical to Headphone; the volume control is bypassed. 

Distortion was very low at 0.05% (24bit, -60dB) and our analysis shows a lack of noise and distortion components – an unusually good result for any portable player, let alone a budget one. As a direct result the all-important dynamic range value measured 112dB, little less than Texas Instruments quote for their DAC (114dB) so the little X1 exploits this chip well.

The X1 2nd Gen measured very well in all areas and was surprisingly strong in critical ones such as distortion and dynamic range, suggesting very good sound quality. NK
