Surge protector

This morning we had a power surge.  First one I ever experienced.  It knocked out the sub woofer components of my GoldenEar Triton one speakers. In my ignorance I had them plugged into the wall rather than a surge protector. Soooo it blew the amplifiers in the sub woofers. It’s going to be a costly proposition: $500 for the amplifiers plus God knows how much the dealer is going to charge for coming to my house. (He’s very reluctant to do it, wants me to lug the 80 lbs speakers to the store.   
Meanwhile, I’m having to listen to bass-less  speakers for the foreseeable future.
So, the moral of the story is plug everything into a surge protector.

@ozzy I've had similar experiences with a whole house unit.   The one piece of gear I lost was a laptop (Macbook Air with amazing battery life, so sad) which was the only piece of kit in my home that was not further protected by plug in strips.

@jea48 -

Class D amps may have a linear or a switch-mode supply in front of them. If linear, it’s just like any other amp and inrush current depends on whether the designer put an turn-on limiter on it or not. Larger amps really should have this feature.

If it’s an SMP supply though there’s almost always a smooth, low current ramp on until it stabilizes and turns on the amp portion.

PS - you can tell the difference by weight.  A linear supply is going to have a large transformer associated with it.

Dammit, I did the Vrms to Vpk conversion wrong..... my bad!

A 120Vrms has a Vpk of ~170V. 

Doh! It's been too long.

I use the Siemens BoltShield, and the reviews are much better. The complaints seem to be from defective units that are DOA or people misunderstanding how the indicators work. Seems a lot of people received pre-owned/defective units from Amazon.

The reviews from Home Depot and Lowe's are also much better.
