Single dedicated line query

Still humming a hawing regarding utilization of a main-connected subpanel with multiple dedicated lines extending to outlets vs a single line from the main with 'pigtailed' outlets. Seem to be a pretty even split with some heavyweight opinions from both camps.

If I decided on a single line, for a 70 ft run from the main, I suspect at least 8 ga (6 ga?)wire should be used. If that is the case, is it practical (or possible) to direct that 8 ga on to the outlets? If not, what is the best method of stepping down to a smaller (say, 10 ga) size line?

A qualified electrician will be doing the work, and in fact once he began hearing of the idea of dedicated lines, asked me about this very issue. I just want to have a better grasp on what is best for my situation.

thanks

At first I went with two dedicated lines from the panel.
One was connected to a 20 amp fuse(source components)the second was from a 30 amp breaker for the amps.

I have since gone to one dedictaed line from the 30 amp breaker using 4 wire Romex 10 guage into a Shunyata dual receptacle which feeds power to a Hydra 2 for the power amps and to a Guardian 2 for the source.

There is absolute silence , except when the music is playing.
There is no power line buzz, hash or hiss,or hum, just a noiseless background.

It wasn't this way with two lines.
