20 hours in. Final E5000, high gain. I never heard such a level of details so far. The E5000 is not a detail monster by itself, but combined with the DTR1 and the FiiO A5 for extra black background, it has been transformed. I am more than impressed now, I am puzzled. How can a player with no EQ, AK4490 single DAC chip and 3.5mm sounds so good? I listened to the AK SP1000M 2 months ago and I was amazed as well. The DTR1 just outclasses it. Only the midrange of the SP1000M remains something special, otherwise no chance against the DTR1. I am wondering about what is achievable in the near future, if the real good and competent guys or girls from Dethonray are going to manufacture their next DAPs and keep that quality. We are talking about basic UI, unfancy design and basic features. Honestly, I could leave the hobby now (see signature). But no. Dethonray will most likely releases new stuff and I want to be there when it comes out. Buy that DAP.
