Dedicated 20 amp lines/should i use a sub panel

Happy New Year to all!!

I am about to install 3 - 20 amp dedicated lines for my stereo. I still have space in my 200 amp main panel but was wondering if their is any benefit to installing a 60 amp sub panel for the 3 audio circuits , also as i am using 10 gauge wire and its not the easiest to manipulate should i hook up the bare wire to the receptacles looped around the screws or inserted in the holes or should i use spade connection's. any advice would be appreciated.

Thanks in advance

Besides having built-in noise cancelling features, and surge protection, another advantage to the sub-panel is that you end up with a star grounding scheme that is short, and therefore much less likely to cause differences in ground potential.

The biggest source of noise in my mind is usually other household appliances, and dimmer switches. If you get separate runs, without any noise cancelling, you are literally just making it easier to pick up noise from anywhere in the house. Having a 30 to 60 Amp subpannel that has its own noise and surge protection is the key.

Best,

I don't think there's a big benefit, besides wiring alone, but there are some interesting options in terms of noise suppression and balanced power at the power panel.

Check with your electrician.
