Power amps into surge protector/Conditioner or DIRECT to wall? Final verdict?

@aberyclark, I believe that blanket advice was good, absent context or other additional factors being mentioned.  Without some knowledge of the equipment, an amplifier could literally ruin and fry a low-end surge protector (picture smoke, I've seen it), even electronically controlled, due to high current draw.   Looking on the back of your equipment might reveal 1300 watts (or 1300 VA rating via inductive, capactive measure) or higher.  That's nearly a hairdryer.  Any other equipment would be fine to plug-in, e.g. the pre-amp, DAC and even TV since those are now minimal draw.  This equipment still might not protect against a lightning strike, but an intermittant surge would be okay.  Direct lightning strikes are very difficult to guard against.  When unsure, just unplug EVERYTHING.  Even in the off state, a lightning strike will fry everything along a path if plugged in.  BTW, the fuses are simply to protect equipment from its own internal failure or as a wide swag protection against external inputs out of specification (e.g. speakers).  Lightning will not care about fuses as they either will not react, or not quickly enough, or it will just arc over.  Grounding is also meant to either protect a user or protect equipment but never 100% guaranteed.  GFCI is also only 99% effective.  All of this is why, when weirder things happen, you can still have electrical fires which is why arc-fault interrupters are now code in addition to GFCI requirements in various locations in a residence.

Whole house surge protectors that are installed in the panel and made by the panel’s manufacturer are a great idea.


However, since the EMP from lightning can be induced directly into wiring, it’s a good idea to put a series mode protector near the devices you most care about. Also, home surge protectors still have activation time. Series mode protection does not.


Last time I had control over it, I had both. A D-Square whole house protector in the panel, and Furman Elite at my stereo.  I have repeatedly found that my system sounds better with the Elite than without it.

So just did some reading. Apparently not all "whole house surge protectors" are UL 1449 compliant. Some are listed as "secondary surge protectors." Meaning the manufacturer expects you to have other devices for your electronics, but at least your big electrical devices won't fry. Might be worth checking which you have.


In any event, I suggest using a surge protector near your gear if you are in lightning prone areas.

 I had my utility put a whole house surge arrester on the meter before it enters the house. Everything in my house is protected after the meter. We have some great lightning storms here in Georgia and my neighbors have experienced issues with their appliances during storms while I haven’t. My ps audio bhk amp sounds the best when plugged directly into the wall but I run everything else thru a ps audio conditioner. During lightning storms, I don’t unplug anything and sometimes I still listen to music without worrying.

When i was using my PS Audio P10 the amp sounded better at the wall
