Ok, I got it now.
Ok let the firmware beside, this player gives bang for buck. And what I also think is that the firmware will be updated properly. What makes me think this? I looked at the Teclast forum. They collect every bug and problem they get from their first customers, so I think the new coming firmware will kill lots of bugs
However, I only coment the SQ. I used Mp3s and FLAC files.
My first impression is that it sounds very good, and in my opinion it beats my D2+. It sounds very smooth, it is kind of balanced, that means nothing is overemphazised. Very warm sound.
Very tight, leans towards detailed, but just enough. It sounds very good with house and Hip-Hop.
How can I describe it best... It is like you move your hands slowly over silk. very good
Here I would say they are a little shy, but still good. With my headphones, which lean towards dark, I would say I need further time for listen.
I would say best genre for this player is classic music. Franz Schubert Symphony No.1 in D major D82 - Andante, was amazing with this player.
I used ESW9 for listening. For me it was definitely worth the money.
