I have a Furman on my main system and a whole house on the main panel. However, if you have lots of wires (cat5, telephone, power, cable, usb, etc.) remember that lightening is agnostic, it will travel whatever is available.
Several years ago, i had a strike on a tree 50' from house. The charge came down the "dog fence" wire, to that fence's transformer (which exploded thru the space my head had been 5 min before) and then on to my PC and my Bryston integrated via house wiring. Took out my mother board but not my drives.
Bryston service repaired the integrated since it was under warranty. However, they said the "don't usually warrant lightening strikes." Pretty much only buy Bryston these days.
