Thank you so much Argentum and Philski! Much appreciated.
I'll probably order from Tube Amp Doctor, since I could go without the VAT and there should be no import tax in Hong Kong I'll need to pay.
By the way, I wonder if anyone have used the EMP / AE / SE with some heavier music?
Because although I mostly listen to classical and avant-garde, there's quite an amount of progressive rock & metal, and some doom metal in my collection as well. I know those will probably sounds better with solid state amps, but from what I read the Earmax amps are very likely The One I'm looking for! It'd be nice if they won't go completely wrong with the category.
