Buying DACs online in Japan is not noticeably cheaper than buying DACs online elsewhere, except possibly for products like the CEC line (and I say possibly because I do not know what street price for these components is outside of Japan).
FWIW, to my knowledge, there are not that many Japanese stand-alone DACs in that price range. There are a seemingly well-made DACs made by hobbyists which are for sale on the Yahoo Auctions but I have never tried any of them and can only comment on apparent build quality based on pictures.
