Allow me to third the recommendation of Equi=Tech *balanced* power conditioners. https://www.equitech.com/ They are the original, and still the best. Equi=Tech is mostly focused on the professional/studio market and does not promote itself or cater to the consumer market, so their products can be a bit challenging, and pricey, to obtain. Other *balanced* conditioners are fine, I use a Furman IT Reference 20i power conditioner very successfully with my "living room system," but I have Equi=Tech for my studio. I can’t point to any real differences.
The KEY aspect of any high-end power conditioning for any audio system is that the output AC voltage should be *balanced* between the two conductor legs, using a huge and heavy toroidal transformer. This will be naturally noise cancelling as well as surge protecting, and will result in a very noticeable improvement in your system's sound. Your wall outlet power is unbalanced, with a "hot" (black) and a "neutral" (white) leg. Fine, and easier and safer, for most purposes, but not for audio/video. I find it odd that most high-end power conditioners don’t well explain this and are coy about whether or not their output is balanced. One often has to read between the lines in their promotional literature. So happy hunting. Beyond balancing the power with plenty of reserve, the differences between the various high-end conditioners are minimal.
