Yes.. Standard amp is 1x AD8397. Balanced amp is 4x opa627 + 4x buf634 (and I'm assuming if used in SE mode, 2x of each). The minibox amp is using 3x 627/634.
I've said earlier it's entirely a marketing flop to call these two cards Standard board vs Balanced board giving the impression the latter is just a balanced version of the first.... I would have named them sth along the lines of "Super Energy Efficient Go Green 12hrs non-stop music board", and "Hi-End Premium Uber Head Blown Board with Balanced".
So standart board will provide 12 hours of music with c/iems?
When Dr. Fang will notice some Europeans are actually following his products but it is pain to get them in here especially with official European prices.
There is one German online shop, I think that website takes preorders but nobody mentions the availability of different amp boards and their prices of course.
Dr. Fang, in my view, you are one of the crazy scientist (in a good way, not insult) but I really wish you could pay attention to rest of the world too not just Asia.
