source for long component and IC

For 25 ft I hope you mean Balanced IC's because they should be fine. Rca's wont cut it (too much signal loss with a low output)

No it would not be balanced...

What is the longest RCA IC (my friend) can run?

20 ft may be long enough

I have Bluejeans LC-1 IC's in my home theater. The shortest are 28ft, longest 33'(rears) and I've been very happy with them. My home theater is a dual purpose (ie 2 channel) systems, and as a baseline I used shorter ICs (Audience Maestro) with my 2 channel before routing the longer set up. It wasn't a scientific comparison, but it was a/b and I didn't notice any adverse impact. It's very quiet, and no loss of signal (that my ears notice)
