Everything seems to running just fine although the TX-SR607 is running a little hotter than I first stated. It keeps the whole cabinet warm. The PS3 also runs warm so when I introduce it into the cabinet as well, I would expect to find a way to keep things well ventilated just to avoid any other issues. If your equipment isn't in an enclosed cabinet, it won't be a problem.
The manual says the 607 has a setting for 4ohms and 6 ohms.
4ohms: Select if the impedence of any speaker is 4ohms or more but less than 6.
6ohms: Select if the impedence of all speakers are between 6 and 16ohms
Note: North American/Taiwan models do not support speakers with an impedence of less than 6ohms.
The "Note" probably explains why I can't find that settings in the setup screens.
