Apart from the nicer case with internal PSU I can't see the justification for the much higher price over the Mercury Popu amp (which is 299rmb on Taobao, around $44 plus external PSU)

Absolutely different amplifiers, different power and boards.
Yes there are rows of pins to fit a daughter board to handle the input options.
Mainly my mods were to power supplies and output inductors, you can get an idea of the kind of mods from pics on my blog which are of the previous generation Popu amp. That one had a fairly major design flaw which has been corrected on the Mercury.
