Audiophile Surge Suppressor (and nothing else)

Furman Elite 15 PFi - plug your amp(s) into the amp outlet and the rest into the same bank or one of the others.  Build quality is great and for me no impact on sound.  I've tried Furutech strips, AQ filters, and Isotek through the years.  The " current reservoir" for amps on the Furman is legit.

Only thing it is not a strip and is the size of a component.

Some good recommendations here that I was not aware of, thanks. 
 

What brought me here? I have an aging Furman PFi 20 that hums, and I am trying out a Puritan PSM156, but that is not going too well. This made me think I should abandon it all and strip down to bare necessities. 

I like my Torus TOT. Yes, it is also a isolation device to reduce noise...

I have a few friends with very good systems that are using the Clarus Duet.  Not sure if there is any power conditioning.

@total111 The Torus products look like a pretty sound product.

@rick_n I had not heard of the Clarus, it seems decent as well, though maybe a little out of my price range when going beyond the Duet.
