I have a question about Streams, purely out of academic curiosity. Looking at the eagle files, the mode/metering LEDs are on a small separate PCB which sits above the main one. All the components on the main PCB are on the front of the board. It looks to me as though if some of the components and routing were moved to the back of the board, the second board could have been avoided completely.
I would have assumed that, especially with the additional parts involved, getting an entire extra PCB manufactured, including adding an additional step to the final assembly process, would be significantly more expensive than having a few SMD components on the other side of the board. Is that true? Or was the decision more to do with wanting to avoid components on the back of the PCB at all costs?
