Looking for budget DAP.

I was browsing all the budget daps in Ali express:

• Shanling M0 : $115

• Hidizs AP80 : $142

• Fiio M6 : $185

• Hiby R3 : $205

(all including shipping)

Considering the major differences against the four, lack of wifi plus music apps on the M0 and AP80, Whitelisted only android apps on the M6, and HibyOS being different android fork, hence can't install apps on R3 and AP80? R3 also having a 2.5mm jack which I guess won't be using.

Very important point : I'll be getting the HD 650/660 soon, so need to drive them too.

Based on raw DAC/Amp performance and UI, which would be the best?

TIDAL is not supported in my country, so should I even consider these DAPs with my CD quality files? I'll be using the DAP with my HD598 and Tin audio T2.

P. S : The LG V30+ is on sale at $360, only if that's better than all of the above.
