Should I redo the AC power in my house?

Probably blown a fuse just having to read "Fremmer" over and over again. The list of things I've done to my AC is long, and trust me, greater than anything you will get installed for $5k. The list of things I would spend $5k on before paying for anything more than one direct line is even longer. If that makes any sense. 

Unlike the other guys mentioned I actually have first hand experience with the relative value of not just AC wiring but a whole long list of other things like fuses, Pods, etc. It is not that AC wiring isn't worth doing. It is. Just don't kid yourself. What I said above. There's a whole long list of things with way more payoff, easier to do- and way easier to take with you if you ever move.

Some of us however have money to burn. Not me. Consider and evaluate accordingly.

The fact that MF said that his system hummed, sort of makes me wonder at how I would trust what is written.

It sounded like his house wiring was "all jacked up" to begin with.
and secondly he got that gear and work done largely for free I imagine.

So yeah, it made a huge difference (from a hosed up starting point)

if you have no problem, then applying a solution will not yield benefit.

What problems do you have? Or is it just searching for some bump up, without and evidence that it can be bumped up?

I do not trust the fellow at all after his glowing review of the state of this house for the decades he was writing.

Mr. Fremer’s wiring was fine until he had some recent generator work done. He went public on the problems he experienced, and rectified the issue. All good.

Fremer Installed a new electrical service replacing the old, in bad shape, outdated one. That in itself would make a big difference. Just look at the old meter socket in the video. The old aluminum wiring connections were corroded. More than likely the aluminum wire connections were not tight either. Poor corroded connections equals excessive harmonic distortion. Excessive harmonic distortion equals noise on the AC mains wiring.

Add to that all the old utility power wiring to new service wiring terminations at the overhead weatherhead were replaced. That can make a big difference...

I did take note of the earth grounding connections methods used in the video. That’s probably the first time I have ever seen Cadweld (Exothermic Welding) terminations used for the connections of the grounding electrode conductor to the earth driven grounding electrode, ground rod(s). That ain’t cheap!

FWIW the main purpose of the electrical service to earth connection is for lightning protection. It does nothing for the sound of an audio system.
