I bought this because after getting the AM2 last time I realized I’d been screwed over. Because right after I bought it, FiiO said: “Every X7 owner gets one chance to buy a module at half price.” So I said: “Well what about me, I already paid full price?” FiiO was very polite about it: “No problem, we’ll have other modules down the road, you can save it for next time.” ……………… So I finally used that chance.
