Power Conditioner/Surge Protector Options

You've already proclaimed snake oil and dismissed responses that rely on experience, so it looks like your mind is made up. Buy what you like and good luck to you.

the EE I work with said the Triplite sucked the life out of his system...but I don’t think he measured anything...I use the Triplite in my basement system, but also have not measured it...

Surge protection limits current and the last thing you want are sacrificial components to protect against surges. Surge protection will also limit sound quality.

You can't beat a large, big and heavy torroidial  transformer. This acts like a reservoir providing conditioned power while adsorbing excess voltage.

I have found Plixir AC and DC power supplies and conditioners to be excellent products, which are balanced in operation.

Plug your power amps directly into the wall, their coils are big enough to protect them.

There is only so much you can do unless you want to spend 10s of 1000s.

The Furman and Niagra are relatively easy sells. Buy all three, you be the judge. Quality of materials, design not just a few plugs in a box with a “surge suppressor” make a difference. 

they are not only easy sells, they can be purchased with 30 day returns...but then listening tests would be required...
