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

The engineer that designed the furman left and went to audioquest. The furman it 20i  has large capicitors to handle the transients on my big monoblock amps. I think 80 amps in reserve. The big audioquests have the same capicitor like magic box with amps for transients as well. My power browns out at least once a wk. I can't risk plugging the amp into the wall. I don't think I have lost any sound quality through that brand of power conditioner, however I have not had a dead amp yet.enjoy the science and the music.

BTW, while I do think protection from brownouts is important (EVS in Furman lingo) it's particularly bad for switching power supplies.  A brownout can cause a transistor intended to be high efficiency/binary to turn linear and low efficiency, burning it out.  

I installed a whole house surge protector that clamps down fast and can take whatever happens to be flowing when the shut down happens, even a lightning strike.

Try the Richard Gray stuff.  Works great

Some really great advice on this thread.  I would add to it by saying: 

1. nearly everything you try unless you get into big bucks will, and does strangle the amplifier.  Going into a wall is best.   For digital sources, a power conditioner is your friend and can pay big dividends in sound quality. 

2.  For me I have occasional DC line noise, which would show up sometimes and sometimes it was fine.  My neighbor got solar panels and the issue got worse.  So, I am now using the PS audio whatever they call it and it's been superb.  It also has DC filtering up to 2v.   I have used power amps into that, but occasionally think I hear a difference.  Using class D power amps (red dragon) and Rogue tube preamp now and tubes and class D *seem* to be less power sensitive, but that could be now I've resolved all the power problems.  

hope this helps.
