Since I purchase topping E50 awhile back, I did not have time to connect on laptop till today to see what’s the hype on MQA. On tidal app, I turn on exclusive mode as well mqa pass through bypass so the the dac will do all the unfolding. My observation, using apps do the first unfolding then dac do the rendering against dac doing all the unfolding. There was distinct that I could hear clearly. Tidal app doing the first unfold the sound was not clear and a bit of haze. It’s like window with streak on it that you can’t quite see what’s outside. On dac doing all the unfolding it was clear that as if there was no window looking directly outside. Now, since I have both amazon hd and tidal hifi plus, they present music in my ear different ways. Again, this is my ear and your ear may hear different thing that I describe. Amazon present music like musician singing infront of you, some user call this in your face. Tidal is like amazon but with added reverb and decay that can be joyful. Everyone has its own preference and taste so in conclusion I am keeping them both.
