Hello,
It all matters, but what is the priority? Power, Power, and Power! It starts from the fuse box. Besides removing things off of the line to your system you have to control the ground. I know MC has done this years ago. OCD Hifi on YouTube has done this. If it didn’t matter in a huge way they would not have done it. It’s not cheep done right if you have to go a large distance or through a lot of complicated walls and floors. The last is if you cannot control the power coming to the room the you need devices. Puritan is the best I have tried. Also it lets you install a separate ground to handle those issues. Puritan PSM156 will filter out the DC garbage on your line and also filter the over the air garbage from cell phones, WIFI, and Bluetooth getting into the power. Most will “condition” and protect the power to the components. Where they lack is what and how they filter. Despite running four 8’ silver coated copper ground rods into the ground for a dedicated ground system the Puritan still helped bring the noise to ZERO. This is how you get the biggest start to a black noise floor. I bought my Puritan PSM156 at

If you are in the Chicagoland area you can try before you buy. No risk plus it will be broken in so you will know how good it is immediately.
