Why is there no gain control on the Adcom GFA-535?

I've used it in between my computer (iMac) and my speakers, and controlling
the gain from the computer works, but there's always a noticeable hiss.
Wouldn't it be better to have the output of my computer much higher and
attenuate the output of the Adcom?

Similarly, I've seen many reviews of powered speakers where the reviewers
complain that there's a noticeable hiss that can't be attenuated. Why are
they designed like that?
