Here is a test of a Lewitt DGT 650 mobile studio I could do by the courtesy of Lewitt Co. They provided me with a whole test kit, and this is my first
testing.
DGT 650 is a USB mobile studio consisting of a high quality stereo microphone (X/Y cardioids 90°) and a high quality USB interface in one housing
connected with a break-out box. It connects easily wit all iOs devices (thunderbolt) like iPhones and iPads. It alsa works with Mac OS and Windows
computers.
It provides high quality recordings with a no hassle connectivity, so if you often work with recording yourself, this might be an option for you worth
considering.
Here is my own test sample done with a Sebastian Stenzel 7 course oud:
