Are there any significant differences between v.1.0 and 1.2?

Is Schiit Modi + Magni one of the best combinations for 200$ ?

Sorry to say, in my country Audioquest Dragonfly costs 300$. It's comparable with prices of devices listed in first message. And in fact I don't need portable device such as Dragonfly, I will use it only at home.

I plug M50 into built-in internal sound card of my PC. That's why I want to buy separate USB DAC.
