@westom shows up again and talks bs about numbers and circuits he doesn’t understand. I think this time he’s switching current and volts.
MOV’s / Shunt type surge protectors are most cost effective at the panels. Noise dampening can also do a lot at the panel itself. I would not rely on this alone for precious audio equipment due to ability of a strike to induce voltage in the lines. A series mode whole-house protector at the service would be huge and expensive.
Series mode protection is best near the devices themselves, and it does not degrade and there is no current flow by design.
When I had access to my service panel I used this kind of dual approach myself. Given a choice of only one, I'd go with the series mode approach.
Best,
