ifi ZEN Air Blue vs ZEN Air DAC

[gasolin]

I thought i would improve on one of the last thing for my sound system, which is the main source, my pc

My M audio M-Track SOLO does a good job despite having things i don't need but wanted to upgrade, just because i can

ifi ZEN Air Blue i didn't find (on a differenet page) but i found the ZEN Air DAC it requires me to connect it for power to my pc where the ifi ZEN Air Blue i could have use my amp for power.

How big is the difference, the price is the same but i ordered it so late i couldn't change to the ifi ZEN Air Blue
