I have placed the order but it will take some time for the items to arrive.?Until then, I'll think about a possible Sound Sleuth bamboo housing design.?Perhaps a bamboo SASS design would be an interesting housing to test (BASS - Bamboo Ambient Sampling System :-)?.I'll take a closer look at the possible SASS dimensions. However, the surfaces would be round instead of flat. Which will certainly make a difference in terms of audio reflection surfaces. Instead of foam I would like to use needle felt. I'll get back to the group once I've created a kind of prototype. I'm really curious about the sound quality of the PUI AOM5024 capsules already. Many thanks so far to everyone who pointed me in the right direction!
