What is your deal Komi, what is it that you want to know about the Diverter that hasn't already been said? Pretty much the only thing he's not posting is the picture of the board, which would hardly entertain you much - Josh has already said that unless you were him you'd have no way of interpreting it. Do you want the heavens to open up and for God himself to announce that this is the #1 USB to BNC converter?
This seems like the whole 'nice guys finish last' phenomenon - like when an awesome guy comes along and he's just too nice for the girl, to where she distrusts his kindness or mistakes it for him having something to hide. Whereas everyone wants the "bad boy," say the old Zero DACs that had loads of reports of problems but that people would always take a chance on to save money. There's so many horrible products out there that people eagerly buy up...$300 Dr. Dre headphones - you realize how much profit they make on those, relative to Josh's project of doing this Diverter from start to finish himself, using his own machines to make everything? Nobody ever wonders much about this.
If you can afford it, try it - you can always return it. Otherwise, you have no business judging it. I don't think anyone on headfi has seen me get this crazy and argumentative about something, I would only say all this unless I was really impressed with the product and then people came and told me that the product is not worthwhile. It made my HD800s go from sort of enjoyable, to exactly how I pictured them to sound before I got them.
