It was fortunate to not have healed the scars before Thomas saw them.
That could have been a bit of a problem.
Power Cables and Wall Sockets
Without knowing for certain, it seems to me that power cables can only be as good as the in-home wiring coming to the wall socket. Is it possible that those who use expensive cables have improved the wiring to the socket? Or is the power from most wall sockets normally excellent, but is limited by conventional power cables?

If the OP’s power amplifier’s power supply was not heavily over regulated, and maybe even then, the circuit that feeds the amp is staving the amp of power when playing high dynamic music material. The dimming lights is proof of that. The AC mains VD may be, (probably is), lowering the amps rated power output. An an oversized high capacity shielded toroid power transformer is meaningless if the AC mains voltage can’t feed the transformer the power it needs to operate properly.

The lights dimming is caused by voltage sagging. Voltage sagging is caused by one of two things:
The voltage drop (or loss) is an easy calculation: V = A * R That is, the voltage lost is equal to the current times the resistance on the line. Since A is a function of the amplifier we can’t really reduce that except by new amps or more efficient speakers. 😁 What you can control:
It may very well be worthwhile to you to get a cheap voltage meter you can sit and watch while playing music, like this one, which not only shows you the AC voltage but the Neutral to ground voltage, in other words, tests if you have a bad neutral:
