You mentioned Pine Tree Audio - what do you think of their Iso-Power 15A Power Filter?
Sorry, forgot to answer this. I’d wait until you can buy a better conditioner like the Core Power I linked above that will likely make a more significant difference. Another option, and what I did, was to wait til a used Audience AR1p conditioner becomes available that you should be able to get for about $200 and then plug this power strip that’s very highly regarded into it that will give you nine outlets. So for around $335 you’ll have a very good conditioner on the cheap for all your components.

But I would still give Pine Tree Audio a call because they’re apparently very helpful if you tell them what you’re looking for, and you may be able to try some PCs on the cheap just to get started replacing those awful stock cords and see if they make a meaningful difference.
