Judging from posts from AudioAsylum, the question remains what makes the AckDack sound as good as it is described. Is it the digital filterless design or the battery?
Either way, Chris Own has described all current production of his Ack! stuff are a departure from Nixon's boards. He also credits himself, post found in AudioCircle, for "properly" designing his new boards which presumes the Nixon DACs are not designed up to snuff.
However, does the difference in design of the board in the Ack! result in a different or better sound than the Nixon? That's the $400 question.
