Hello guys and thanks for checking this thread, I am going to purchase the first Hifi products at the end of this month, It is near, What I need is to know what amp/dac I need to drive let's say a headphones with 120 Ohm impedance and 101Db sensitivity (like k601) I am settled on few options, The max thing is xduoo xd-05 and cayin c5, Can you guys tell me if both can drive them correctly?? any pro here please?  I checked NwAVguy's tutorial and I got nothing

 Would like to hear an accurate answer with details
