I had my entire service panel replaced about two years ago. Per his company's standard practice, the electrician put in two ground rods, located about five or six feet apart. He also installed a Sycom SYC-120/240TC whole house surge protector, which appears to be generally similar to this model except that its label indicates that it is rated for a surge current of 150,000 amps. It is mounted on the side of the breaker panel.
For the audio system itself, like a number of other members here I use this Brick Wall "series mode" non-sacrificial surge suppressor/line filter. Its eight outlets are not quite sufficient for my purposes, so I use a Hammond power strip to multiply one of its outlets, plugging the less critical components into that. In addition to surge protection the Brick Wall also provides some degree of noise filtering (specs shown at the link), both on the incoming AC and between its four duplex outlet pairs.
Best regards,
