+1 for @cey comments. I have both the zhili audio clone as well as the real mccoy EAR unit. They sound identical. The only thing I would be suspect of on the Zhili clone is the step up transformer option. Not sure who supplies them.
Either unit will also make an excellent tape head preamp unit. The EQ has to be changed and the feedback reduced a bit to get a bit more gain, but it works quite well.
