For what it’s worth, I installed an Eaton whole house unit in the main panel and have ‘gasp’, 2 ea ZeroSurge 8 outlet units for my HT/stereo equipment stuff.Exactly. Install a surge protector at the breaker box or main panel to protect the entire house and be done with it. They will provide better protection from minor and major spikes/surges. You can for redundancy sake add inexpensive surge protectors on crucial equipment if you care to.
With easily in excess of 30k in equipment it just seems prudent to try to protect the power supply (we have lots of thunder storms in TX and unplugging stuff to try to prevent it is inconvenient if not impossible.
