James,
I assume you are talking about speaker connections.
The TX-SR805 does accept banana plugs. BUT!!!
This depends on how much depth you have to work with in your installation.
I have the TX-SR805 that is deep tall and heavy.
From front to back including the speaker binding posts the 805 is about 17 ¾ inches deep. I wanted to use banana plugs to simplify installation, but the AVR would have protruded over 1 inch from my audio rack. With all connections hooked up, audio, video and speakers the AVR just barely fits flush without banana plugs.
