I got a iBasso D-Zero last year and i feel like it's time for an upgrade.
Headphones I ow as of right now
1964 Triple CIEM
Sennheiser HD 650
BrainWavz HM5
Ultrasone PRO 900

Will get UE 9000 or Parrot Zik next week.
Budget is $50-200$ at the most.

Needs to be a Portable Headphone AMP/ with a DAC feature

Your D-zero is $109 and a slight upgrade to a $50 - $200 amp range is kinda injustice to your headsets....a higher price range would be a better upgrade though. Check out Fiio, Headamp, or the bigger iBasso amplifiers.
