I needed to run the review through Google Translate but the reviewer seems to be looking at the unit from a technical point of view rather than a user perspective. Anyway I agree the review does seem a little unfair.This japanese reviewer takes the cake, gave 1 star without actually listening:

The iBasso DX320 the reviewer mentions may be worth a look as a comparison to the WM1AM2 though, I expect it will be around the same price point.
