FiiO's wheels never seem to stop spinning, as if they're racing down the highway at high speed. They seem to be in constant new device launch mode as soon as you watch them introduce a new product.
In the past six months, they have released BTA30 PRO, FH9, FD7, FA7s, KA3, and so on. Do you understand what I'm talking about? Oh, I'm not complaining at all, and don't get me wrong.
