Nathan Amp Train

My Nathan baby like and love so much “huo che” – the Chinese name of Train,  one day we playing his new Train, then I realized that, the power amplifier extended board could be connected like the way the train attached, and so (to cut the story short),  I name the 3rd series amplifier as Nathan Amp Train.

Here is the idea :

I, myself don’t need the Nathan Amp Train and I don’t have any prototype to show.  I will present the idea to DIYers, Hobbyist, Audiophile and High Power Mobile User see if they like the idea, and will make it into real hardware.
