Accuphase pricing Japan vs. USA

and if you buy grey market goods no parts or service

And often the same if you don't .

Regarding pricing in different countries, it also depends on the image branding the manufacturer has adopted for a particular country. In the US, Mercedes cars are marketed as high-end, exclusive autos. Meanwhile in Europe, while you still see the fancy models, you'll also see the brand used as taxi cabs. 

It is not unusual for a manufacturer to adopt different approaches for different countries with a more common mass market line in one region (often their home market) and a more upscale only approach in other markets where they may not want to scuffle with the hoi polloi competitors.

Its not always about Greed, The Taxes, Imports Fees, Marketing, Handling Stocking Gear, Supporting Parts and Warranties, time and effort to run the business. all this requires funds. I'm sure The Dealer can come to some form of a deal if you push it at. 

If you buy direct from Japans something goes wrong can you speak Japanese and get it all sorted out with parts being shipped? Whos gona install it if boards burn out?
