Amp for my Audeze

Hello!
I have recently managed to buy an Audeze LCD 2 Classic for 700$.
Now i’m looking for an Amp for them, i’m between Project Ember 2, Xduoo TA-20 or Massdrop 789.

789 will work fine with most headphones.

  1. 789
  2. closer budget option is atom

i have the 2C too, and i use atom

Thanks guys, i have decided and ordered for the 789!
