I was thinking about the Adcom this morning. If you assume that your source components have two-position power switches (as was the case with older two-channel gear), the Adcom's arrangement makes perfect sense. Even if your equipment came with remotes, the two-position power switches still required you to walk up to the equipment to turn it on. Having a single switch to flip that would power up those devices is very useful.

When you move to modern home theater hardware (which for something like a surround processor or a Blu-ray player really means a purpose-built computer), the two-position switch is gone. Having remote on/off required that change, and the front panel power buttons today are all momentary contact. That is why I have a hard time with the idea of switching power to a surround processor. It's meant to live in standby mode unless you know you're not going to use it for an extended period and want to unplug it so it's 100% safe from power anomalies.
Sounds like a good purchase. Unless you see a lot less "turbulence" on your AC power than we do here (which is possible since you're north of tornado alley and the fun storms that come along with that), the MOV's in 15-year-old surge protectors have probably done all they can do to protect against surges and are no longer offering much security.
