boostedis,
I’m not sure of your budget so here is my opinion. I somewhat agree with what has been posted. But I gotta say the AudioQuest Niagara 7000 exceeds every type of conditioner that I have tried. In sound quality that is. And isn’t that what it all about with this hobby?
Look up what it consists of. Heck look at pictures of the internals, it is more than just a surge protector or a bias negotiator with plugs.
Up until this conditioner I also thought that the power amps sound better straight into the wall. But with the 7000, my mono block amps, subwoofers, even my 85" Samsung is better plugged into the big Niagara.7000.
No scientific backing just experience, exactly the opposite of what you requested, sorry. Since you are a relatively new poster, don’t start off with a closed mind, try it.
