For those that aren't aware, I'm back, and am gearing up for more testing. Figured I'd add a link to the new thread here, for the people that haven't been around in a while, or those who find this via google. There is a go fund me for the next test rig, which will be night and day better than the one used in this thread, and it will be a permanent addition to my garage, enabling testing for the foreseeable future. It will be able to run tests at multiple temps between 50-110F, record audio during the tests for people to hear and analyze in audacity, and have a significantly lower noise floor than last time.
