Kinglet was originally a nameless audio subsystem which consisted of used audio devices and was used for background music in my study room. Recently, it has been improved so much to be a high-quality audio system that can be used for music appreciation. It is also used for checking power amplifiers and some audio experiments. It lives up to my expectation. So, I gave it the name ‘Kinglet’.
