Surge protection for amps?

If a surge (ie 20,000 amps) connects harmlessly low impedance to earth, well, an IEEE Standard defines that as 99.5% to 99.9% protection. Only then can a plug-in (ie series mode) protector do something useful - add maybe 0.2% additional protection.

Surges are defined by the independent variable: current; not by a dependent variable: volts. One must know that before making even subjective recommendations.

Series mode protection is for one type of surge. And literally connects a surge directly into attach appliance once it has absorbed it maximum energy - typically 600 joules. Series mode protectors are hyped without numbers (ie a near zero 600 joules). Also ignored: another wire connects a surge directly into electronics - bypassing a series mode protector that cannot do anything about it.

Electronics already have protection superior to tiny protection provided by a series mode protector. Even simple numbers (that are ignored to promote a tens or hundred times more expensive solution) make it obvious. Proven protection is defined by an answer to a simple question: where do hundreds of thousands of joules harmlessly dissipate.

How does its 600 joules absorb a surge that is hundreds of thousands of joules? Series mode protector promoted again by one who constantly ignores and never provides relevant numbers.  Including current, joules and an IEEE number: 99.5% of the protection.

Series mode filters are for a completely different anomaly - noise.

I just bought the Shunyata Research's Venom package; 20,000 amp protection +power conditioning.  It's a 4 piece package retailimg for $995.00

Google Shunyata!

Even though minimal and effective protect is 50,000 amps and costs about $1 per protected appliance.  Even though Shunyata Resarch spec numbers do not even claim to protect from potentially destructive surges.

I use the PS Audio P600 which provides protection and regenerates the power to my components. I have a friend who has the PS Audio P10 which is a later reincarnation and has many more bells and whistles if you want a more sophisticated power regenerator. If you have not tried a power regenerator I highly recommend you compare it to your power conditioner. Yes, the power regenerators are more costly but the sound impact is worthwhile.
