Power

Good point. If you will be in the home a while, and especially if you can DIY, then running one line direct is the best thing you can do within your budget. That was the first thing I did, even before getting a conditioner, and was totally worth it. If you DIY, and depending on how long a run you have, you might even be able to budget a good Synergistic or Furutech AC outlet in there as well.

Without getting into my power management situation, I will give some judicious recommendations:
1. Agree if budget allows to put in a dedicated 20amp line direct from the breaker box to your listening room. 2. Agree with premium outlet but with non magnetic outlet covers. Makers of such have been mentioned. I will add Shunyata Research outlets which I have. 3. Power conditioners: IMO optimal one of the PS Audio PowerPlants. They make at least 3 models at different price points. Otherwise, an Audioquest Niagara. Again they have different models at different price points. All of them good. 4. Power cables. There are so many on the market. I personally like and use Shunyata Delta NRs though I have one Delta V2 XC. I am sure Synergistic makes good ones too. I have one or two of them. For more of a budget cable check out the upper end Pangea amp cable. I forget the model number. I bought one to try as it was relatively inexpensive. The attractive feature to it is that is has the thickest gauge conductors of any cable I have seen and gauge is important. So far I like this cable very much and I am trying it on my Raven Blackhawk Mk3. Good luck!

Neither of those things will affect audio quality. Save your $$
