Just received them and am blown away. The quality is INSANE. The finish is also beautiful :) Question though, I plugged them into a power strip, no issue (I only had the speakers plugged in and audio was coming from my phone). Then I moved them, the strip, and plugged in my pc, monitor, wifi router, and speakers all into the same strip. Now when I play audio through the pc, I get a high pitched, quiet buzzing. What is this and how would I fix it? Thanks!

WapeyLooks to me like that's either 1. Electromagnetic Interference (EMI) from your computer's noisy DAC or 2. a ground loop caused by your LSR30Xs being plugged into the same strip as a device using a different grounding potential.
Try experimenting with different outlets and power strips. What happens if you plug your speakers into a different power strip on the opposite outlet of your main power strip? If that doesn't change anything, then what happens if you plug your speakers into an entirely different outlet on the wall? If the noise goes away, it means you have a ground loop. To solve that while keeping your current power strip setup, you would need to buy a "ground loop isolator" that has the connectors you need.
If the noise doesn't go away regardless of different outlet/power strip setups, then that means your computer has a noisy DAC and you need to buy an external one.

WapeySounds like you are generating a ground loop/electrical interference, likely do to your pc's poor power supply. If you have a laptop trying unplugging the power to see if it goes away. There are a few things you can do. 1. Get a better source that doesn't have a grounding problem 2.Get a device like this to remove the interference https://www.amazon.com/gp/product/B0002M5OJI/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 3. Get a device like this (you can get them for 1/4 inch too this is just an example https://www.amazon.com/MagiDeal-Suppressor-Electrical-Headphone-Eliminator/dp/B01HCDSN8S/ref=sr_1_5?s=electronics&ie=UTF8&qid=1515873008&sr=1-5&keywords=headphone+jack+ground+filter
