I think five amps is about the limit due to added noise and cross-mod.


In practice, without serious and constant TLC, the length of cascades of
amplifiers is usually limited by the frequency response flatness (or lack
of it), and the ability to maintain it. I think that the maximum I've been
involved with was a cascade of about 20 normal trunk amplifiers plus three
or four distribution amps / line extenders on the end. Thank heavens these
days for optical.

20! Wow! That would have to be some high-grade stuff. Thanks.
