Surge protectors--how many $ make sense?

OP:

Be careful as some are marketed as "offers surge protection" which is different from having a UL or ETL certification as a surge protection device. Actual surge protectors will be certified to UL 1449.  It's the difference between throwing an MOV into the box and actually undergoing high voltage testing.

I have had great luck with using computer type Battery Backup/Surge protectors. My approach has been to use relatively high power units that will support a load of 1000 VA or more and use those in sufficient numbers to handle the current draw of the equipment. The good news is companies like APC will warranty the equipment connected for replacement cost up to a fairly high value...as yet I have never had to collect on that warranty and hope I never do. It is a source of peace of mind to know that the warranty is in place.

My power surges 2x a wk and I have furman 20 i that have never failed me.there are some on ebay open box about 2k.a whole house would be good as well.sorry it took a fire to stimulate.

Some used furman 20 i on the music room now 1.5k but I would go open box

I have run krell fpb 6k watts into 1 ohm mcintosh 1.25k bryston 28 b3 and many hive 10 k watt class d into the 20 i and have never had an issue.yes I would prefer plugging them directly into the wall but don't want to lose a high dollar amp.the furman may Rob 1%of sound quality but that's the trade off.the 20 I has capacitors with>60 amp transients power so does audioquest 7000 but it's 11 k. Many furman 20 i in recording studios. Enjoy the hunt.read alot of reviews.the shunyata is a good one they cryo thier stuff to align the atoms to make electrons flow better.
