So I went and searched and yes, there are few items, but nothing really to destroy a dealer. No high value items at all and prices and not that much lower.
B&H Photo used to sell both white and grey items. You see, there is no really white and grey Denafrips since local US support is very limited. It is not like you buy Canon lens US model with quick local repair. Gray or white most probably you will have to ship unit to Singapore.
Grey market is good. The only way to fight greedy monopolists like US importer of Accuphase.
