Surge protection


My apartment recently had a serious power surge. To my horror, a few pieces of equipment were killed! Aurender was great for repairing my N100. Still waiting on the status of my Walker precision motor drive and Meridian Headphone amp. 

It’s been my understanding that surge protectors degrade the sound of a high-end system. But going forward I feel I would be foolish not to put surge protectors in front of my expensive equipment.

I would appreciate any advice about what works without sound degradation,

I totally agree with erik_squires and dpop .

I had my system connected to a Tripp-Lite when the neutral wire to my building broke sending 240 volts into my building , burning out 2 refrigerators , exploding light bulbs and taking out the Tripp-Lite which saved my system from any damage .

I now have almost everything in my house connected to a Tripp-Lite Ultra ,  but I still have the amp connected directly into the wall due to the current rating of the TLU.

   

I know battery back up is not a replacement for surge protection, but does anyone use UPS for their low power equipment, such as dac and streamer, or CD/DVD player? I use one for my router and modem in a different room have had improved reliability, likely to to less brownouts which are more common where I am at. The unit says surge suppression, but not sure if it works well for that. I don’t think I have many surges.

This is what I use for surge suppression (not UPS). No issues, but like I said, not a lot of surges that I know if in my area.

I do, and it’s a double-conversion 1500 VA UPS (always on battery power, with zero transfer time).

Even though this UPS incorporates surge protection in its design, I have placed a Tripp Lite Isobar Ultra before it, along with a Furman PM-8 Series II Voltage/Current monitor (with Series Mode Protection - SMP) after that (to protect the electronics in the UPS). Those two devices in series then feed the UPS. I’m all about protecting my gear as much as possible. Post UPS; two balanced AC transformers then take that UPS power, and convert it to balanced AC.

If you’re referring to AC THD; when I owned a Fluke 43b Power Quality Analyzer, with nothing plugged into the UPS, the THD was 0.0%, with a perfect 60 Hz waveform. It just doesn’t get any better than that (as far as I know). As gear was plugged into the UPS, the THD did rise, but never exceeded 2%. If you were referring to physical audible UPS noise, well then yes, there is some of that, so in my case, it is located out of my listening area.

I recommend the Furman PST-8 line. Tested by Wirecutter and the let through voltage is low.

 

I had a different Furman unit a while ago (an M-8, I believe) and it seemed to have protected my equipment while I was away on vacation. Came back to find the 'Extreme Voltage' LED was lit and the unit was off. Once I reset it, all the connected equipment powered on as normal.
