is zen can worth it with 'easy to drive headphones'?

hello hello. i have a zen dac v2 and this... this is quality. the end game device of your life.

since this one is so good, the curiosity of the 'zen can' goes up. i have MEZE 105AER , and 99 classic. easy to drive, sensitive headphones. and the v2 doesn't sound insufficient at all. do you guys think the zen can is worth it for the 'extra' honey sound? or ... it is not needed unless you have a 'very hard to drive' headphone? is the 'sound' of zen can worth the extra purchase? how do you guys think?
