Just my two cents:
I am also the proud owner of a cinnamon altoids from JMT which I have been blissfully using for a month or two now. I agree with most of what has been said--it drives my 580s wonderfully, I like it alot with my etys (amp/ety review coming some day), and it is overall much cleaner, precise, and less dark than the TA (which I like alot too with certain phones). It also makes my ks35s sound really good.
The amp is sweet. I love it. And the mints were yummy I suspect(my wife ate them all).
