I have had two installed in my house (20 years apart). You just want to find a licensed electrician… not that you can’t do it yourself. Expect them to look at you like you are crazy. Just tell them to do it. You will be very happy. You want two, one for your main components and a separate for your amp. Go for 10 gauge Romex unless you want to get really fancy with special wire. Use hospital grade duplex receptacle unless you buy audiophile ones.
But running 2 10 Gauge Romex direct lines will significantly improve the performance of your system. Well worth it.
