This is a great case. I'm not giving 5 stars because of the lack of spacers. Khadas original spacers are too long for this case and none is provided with the case. Even though spacers are not needed (the rings subjecting RCA connectors are more than enough), it is a pitty Audiophonics does not offer appropiate spacers as an option. Just spacers M2*5 mm female-female and 2 screws M2*5 mm (see review by Rainer E.) is all that is needed and would gladly pay 1€ for them. Please Audiophonics, provide the spacers or remove the holes in the case intended for them.
