Basic surge protection with some noise filtering without strangling the amplifier?

Thank you all.

Although we don’t get much in the way of lightening here in the Pacific Northwest, I do worry a bit about power surges from other sources. I’m going to take Furman at their word about their “revolutionary Power Factor Technology, providing a surplus current reserve of over 45 amps (peak) that enables your amplifiers to operate at maximum efficiency.” That is a lot more than the 20amps coming out of the wall after all.  And as @fastfreight surmised, I will have 30 days to return them if they do strangle the amps.

For sure you are right for protection aspect.

If i was leaving in a location prone to sudden tempest any hours of any day i will do the same, nevermind a bit less satisfying sound, but i am lucky where i live is relatively calm and thunderstorms are previsible in some way.. Then i disconnected my amplifier ...

Any surge protector with series mode protection has excellent noise filtering built in, due to the nature of the protection.  Furman with LiFT adds linear noise filtering.

Regardless if what others say the "rule of thumb" is, I surge protect everything due to living in an area with continuous affronts to the electric grid.  Damage warranties are almost never enforceable and I don’t want to go through the hassle of repair or replacing anything. 

I live in the Pacific Northwest as well.and have had my amps plugged into the wall for 25 years with no ill effects. 

I would highly recommend to you one of the Audioquest conditioners/surge protectors that are within your price range (new/used), like the PowerQuest 707.  And if you could somehow find a way to move up to the Niagara 3000, that would definitely put you over the top for ultimate power and surge protection for the foreseeable future.  I believe that the PowerQuest 707 would fit your needs just perfectly, and it doesn't cost an arm and a leg either.  I have my very high powered integrated amp plugged into an Audioquest Niagara 3000 with incredible results.  I found that the Audioquest line of conditioners/surge protectors are excellent at  getting out of the way and not restricting the power and dynamics of high powered amplifiers.  Even the lower priced Audioquest conditioners do an excellent job!!!  Happy listening.            

@mahgister - There's no better surge protection than unplugging a device from the wall.  I also know that here, 90% of the time a power event happens I have no warning at all.
