A Surge Suppressor Story

I was recently redoing my audio system and, when putting everthing back together, temporarily plugged my Bryston B60R Integrated Amp directly into the wall outlet instead of the Zero Surge suppressor. I checked everything out and let the system settle in over the next two days.

I then noticed that non-musical sounds would pop out of the speakers from time to time. In particular, a loud thump occurred when the ceiling fan in the room was turned off. It suddenly dawned on me that the Bryston was not plugged into the suppressor. Motors are known for generating back EMF and I was surprised that the internal power supply in the Bryston was not rejecting it. With the Zero Surge unit in place, the internal reactor took care of the problem very nicely. Cheap surge suppressors using "sacrificial" metal-oxide varistors (MOVs), however, would not have done the job.

Reportedly, 80% of all surges/transients in a home's electrical system are generated by appliances in the home. Anything with a motor is suspect. I believe that continuous "hits" with surges and transients will shorten the life of the equipment. If you value your equipment, consider the protection offered by a good series-mode suppressor. Reasonably-priced units are available from Zero Surge, SurgeX and Brickwall with audiophile versions (Audioquest Niagra, etc.) costing considerably more.

Those with large, power-hungry amps have complained that dynamics are affected by suppressors compared to plugging directly into a wall outlet. That may well be the case in some installations but protecting expensive equipment may be a worthwhile trade-off.

It's excellent posts like these, where people like oldhvyec and gdnrbob chime in with the OP on important to all of us issues.

It was posts like this one that brought to my attention issues I'd never really considered, and make perfect sense.
When I was looking for a good conditioner, and I did like one, which reviewed very well, it was surge protection I also sought, because of threads like this. I didn't respond much in those threads, just read about things I didn't know, or hadn't considered.

I still was very interested in one product, until another Agoner posted and responded to my PM, he introduced me to a product not even on my radar. What I purchased implemented the same technology as the one I had been looking at, and it also offered surge protection and removing DC from the AC. This was the one for me, because of Agoners who posted threads like this one, I believe I was able to make a more educated purchase choice.

Thank you turnbowm

I have a regenerator.
It's docs recommend unplugging it during a storm.
There's that.

In the mountains of Colorado our house has surge protection. This summer a rogue lightening storm, (few clouds, no rain) hit our house...this was the western side of our house. Most storms will give some warning but not this one. We lost two computers, two televisions, a microwave, an iron, two clocks and a couple of light fixtures. I run into my stereo room cursing and found my Magnepan 1.7i, Parasound Halo 21+amp and PrimaLuna Evo 300 pre amp (all recent purchases) all unscathed. I believe I need to thank my Shunyata Venom package. Yes the stereo room is on the eastern side but I believe my high quality surge protector and line conditioner saved my electronics.
