Please, do not take me wrong, I appreciate all the Chinese manufacturers efforts, I use and like older FiiO players (not new ones), I like shanling M0 very much or xDuoo digital transport, even half baked Hidizs AP200. However, DACs and head phones (mostly) are not up to the European or US products (in the same price range) - DACs like Chord, CEntrance or iFi, phones from Beyerdynamic, Sennheiser or Grado, even cheapest like Beyerdynamic Soul Byrd sound much better than almost any ChiFi, as exception is Dunu (like DN2000j). After getting bunch of Chinese IEMs DACs I finally gave up trying and gave away most of that stuff. Yes, I tried Topping also but they lifeless and flat, lack excitement, went away to someone. Simplest CEntrance DACport HD beats them all. On the positive side - Chinese tube amps could be pretty good but I guess these are very mature technology:).
