My experience has always been to keep the ic's short as possible and of good quality. Longer speaker runs will generally result in a loss of gain but the frequency response will remain intact, again using good quality runs.
As Argyro said, the ic's are carrying a more sensitive signal.
How far apart are your speakers going to be that you need 25ft speaker runs? You must keep the speaker runs the same length, I'm sure you know.
