Who is more Knowledgeable?

As I was reading Book X, the part about the three arts caught my attention. The text says that there are three arts for each thing: one that will use, one that will make, and one that will imitate. It goes on to say "the man who uses each thing will be most experienced and he will report to the maker what are the good or bad points in actual use of the instrument he uses . . . doesn't the man who knows report about good and bad flutes, and won't the other, trusting him, make them?" (601d and 601e) I was a little bothered by this reasoning because I don't feel like it rings true in every situation. When you think about it, it could go either way, but I would argue that the maker knows more than the user. A person who builds computers undoubtedly knows way more about how they work and what constitutes a good computer versus a bad one, while an end user can simply know how to turn it on and access limited functions. In this scenario, how would the user be more knowledgeable?

I agree with Socrates that the imitator has to trust one of the other two when he paints (or whatever his form of imitation is), but I feel that it's more of a give and take between the maker and the user, a mutually beneficial relationship that leads to the best possible outcome. The maker receives feedback from the user and turns it into knowledge of why something doesn't work properly and then can therefore craft it differently to solve the problem. Without the user's feedback, the maker couldn't fix the problem, but without the maker knowing HOW to fix the problem, then the user's critique is of no use.

What I have brought up may seem like a small aspect of the chapter, but I think it is a valid point to consider when going on to discuss who has the knowledge of fair and right, and who else is just following orders.
