One of the reasons I was attracted to and purchased the q5 was the ability to update amp modules without having to purchase an entire new product.
Fiio's inability to address this issue leaves me to conclude that fiio only wants consumers to purchase the q5s and not have the ability to upgrade the q5.
This is not what their previous marketing of the q5 indicated.
Does anyone forbid you to by AM3B or AM3D amp module for your Q5?
