So I searched the forums but found no clear answer.
I just bought the Hifiman HE-500 and I am using them on my E17. The sound seems fine for me as I have no experience with great headphones, but I wonder if the E17 is giving them enough power. If not, I'd like some recommendations on a good amp and DAC setup. I read about O2+ODAC combo (apparently not great), Lyr + Bifrost (too expensive for me), or Hifiman EF5 (again too expensive).
I'm searching for both an amp and DAC (using USB) for around $400-$500 total that would give my headphones a good increase in sound quality. Thanks!
