FYI the latest drops of this unit only come with a 1 year warranty, according to Massdrop support. Despite some of the comments indicating there is a 2 year warranty, that was only for some of the drops from 2015. My unit still powers up, but no sound comes out the RCA connectors. I was told by Massdrop support I am not under warranty, despite basically being still within the 2 year period.

Will the medium gain amp be powerful enough to drive the HD6xxs?

I'm stuck between this or a JDS Labs Atom, anyone have either or both and can recommend? New to this Amp thing, have been using a focusrite scarlett solo that I bought for a completely different purpose, should I even get an amp? Just got the Drop Meze 99 Noir.

For me the decision is between JDS Labs Atom and Magni Heresy. I'm leaning toward the Hersey but not by much. The O2 sold here on massdrop isn't the greatest quality based on what I read below. Isn't the meze easy to drive? A quality amp helps but you'll have diminishing returns. If anything it's a new toy which will automatically for that reason make things sound better.

Will this drive a pair of Beyerdynamic T90's? I bought a set from a friend but ultimately too cheap to buy a 300 dollar amp he suggested. I'm not really an audiofile, just a musician that likes to listen to music. I also would like to drive some bookshelf speakers and a powered sub.
