I'm really waiting for your review @DJScope as this will be the deciding factor if I should wait for the X7.
 
I'm looking for incremental upgrade with my Xduoo X2 which I really enjoyed the sound coming from it. How does it stand compared to the sound quality of Fiio X5?

@moracajay Funny enough, the xDuoo X2 is superior to the X5 in detail retrieval, authority, power and battery life, but the X5 has got it beat everywhere else. Considering the excellent sound capabilities, power and price, I would pick the X2 every single time.
