iBasso dc01 or anything else for 40ohm headphone

[goldenrock00]

Hey there. I have Sony MDR XB-950 and it is a 40ohm headphone. I can not get the maximum volume. I want to buy a dac/amp for it. I can prefer iBasso dc01, tempotec sonata hd pro, jade audio ja11 or neoteck ntk106. Im gonna use it for my pc and phone. Which one would you recommend for driving my xb950?
