The main factory is located in Saiwai-ku, Kawasaki (Japan). You can buy directly from the factory if you are in Japan on the main web website under the tab Direct Shop. www.final-audio-design.com. Please note that we are currently making changes to the Japan only store but they should be done in the next few days. If you need help once in Japan and cannot get through to the factory shop let me know and I will have someone from Japan contact you directly.
The main company website above also lists under the Dealers tab the stores who carry Final product in each country along with their contact information. Many of them do have demonstration product available to test in-store, but you would need to confirm with the actual store as to what they have. This is also having some changes made to it to update the Global list, should be completed soon as well.
I'll check it out....
