@drmuso when I looked Friday it said 20%.
Anyway, I just went through a review because my Topping D90 AKM4499 needs replaced. The tariff has many people confused, including manufacturers. I will list some brands that are good IMO.
Border Patrol, Denafrips, Gustard, Holo to name a few. You can find the model that suits your budget the lowest cost R2R i would buy is a Denafrips Ares. Used $750.
I can never make up my mind. I just purchased a Denafrips Pontus 12 used. Used hold their value. They have sold lots of them. I would have purchased a new one but the current situation made me want to steer away from getting one here from China. People are selling any new ones at or above list.
