Xnyocn X1. How this unit went almost unnoticed to the portable Audio Enthusiasts radar baffles me a lot. After extensive A/B with my personal favorite dongle, the Ovidius B1 – I am staggered by how similar the two of them performed! It is no secret Ovidius B1 is my firm personal No.1 among over 20 dongles that I have tested. So, the manner for me to describe the pros and cons of this X1 are similar in many ways. So how do they actually compare? For starter I would say slightly meatier dynamics on Ovidius B1 otherwise similar timbre and tonality. Very slightly richer bass Bass/Mids/Treble decay textures on Ovidius B1 while X1 exhibited a leaner version – however with equal length and cut-off. X1 also seems to be very slightly less airy compared to Ovidius B1. On the perspective of transparency and resolution, Ovidius B1 remained superior among all of the dongles I tested – and this X1 just a step behind it. Which also mean X1 is not as punishing in revealing the artifacts of bad recordings or sources. But still best not to use Ovidius B1 and X1 on lossy MP3, you will hear all sort of imperfections. Lastly, X1 is just a tiny bit drier sounding compared to Ovidius B1.
It is mind boggling how a seemingly nondescript item can exhibit such finesse. This X1, Stellar!. And yes, DON’T use this X1 on low impedance or highly sensitive IEMs, you will likely get floor noises. To mitigate this, use Impedance adapter with at least 47Ω of resistance.
Best Pairing: High Impedance IEMs/Headphones between 36-250Ω
