I'm a total newbie when it comes to hi-fi. I recently bought Denon AH-D5000 which is my first high-end cans. I really enjoyed it but still feel something is missing. After tons of research I realized I need a DAC, but not sure about whether a headphone amplifier is necessary. My budget is a bit tight at this moment. I'm looking at Fiio E10 or/and E11 or E17. Can anyone give me some opinion? On a side note, I can get little dot I+ for just under $100.
Thank you all for helping me out.
