Transparent's Network Boxes

I know this has been a topic before but I was wondering if anyone really knew what Transparent puts in those cool looking black boxes. God knows they charge enough for their cables and one would think they would put a picture of the network box contents on their website but no such luck. I've heard everything from a single cheap resistor hot glued in place to exactly three parts in each model no more or less. I've researched this on audio asylum and the opinions vary as well. If anyone knows for sure and better yet can direct us to a photo url, that would be wonderful.
