I am looking for a headphone amp for the HD650.
 
Primary focus is quality DAC, AMP.
Input output wise is only need USB input and headphone output, rest is optional.
It's not an issue if it needs external power supply (does not have to be usb powered).
I would prefer a device that can work without needing to install a driver.
 
Max EUR 350. Ordering from Austria.
 
Any recommendations?

HRT MSII + Schiit Asgard is a good setup

for that budget ODAC + O2 are probably without real competitors. 
 
and buy from:

or

I've just ordered mine for my HD650

To me the HD650 never sounded as bad as with the O2 :\ Personal preference

Schiit Magni and Modi might work for the price?

Magni or Vali/Modi stack might work.
