+1 MC. Dedicated outlets is often a very cost effective improvement. Obviously depending on your routing situation. It could get into the thousands if it’s a really hard run. Could be as low as a couple hundred bucks or do it yourself if you know what your doing. I had to do a little drywall ceiling work to get 2 dedicated lines into my basement but no big deal. I think I spent $500 total to pay my buddy labor and materials. Well worth it.
Other factors affecting sound
I'm building a dedicated room in my basement and was wondering if I should care about in wall electrical wiring and Receptacles. Do these generally make a big difference. I assume anything should be better than builders quality material. Are there any specific recommendations? What about whole house surge protection? Also, I have an option to install a second electrical box, is this helpful? I have a 5000sq ft house in suburban area with very few houses near me. I have clean and stable power. Recommendations appreciated.
