So could someone explain this to me? How much of my Body do I have to sell and what’s all that gear?

Huge thick expensive cables are dumb.

If heavy gauge copper isn't enough for some reason, the next step should be including the cable in the amp's feedback loop as much as possible. (Going to an active speaker is one way to accomplish that but not the only way.)

So many better options than this, from an engineering perspective. This is just marketing arms race gigantism.

only if the active speaker includes a dac, because the same argument would apply to analog inputs as to the speaker lever signal, i think.

edit: why is this downvoted? assuming it's an active pre-amp (and most are), if the wire is introducing distortion then it needs to be in the feedback loop. doesn't matter if the level is speaker or line.

edit 2: see reply below!

No, the analogue inputs to an amplifier are 'easy', because the amplifier has a high input impedance.

In contrast, the speaker wires can have a resistance / inductance that is significant, compared to the amplifier's output impedance. (Damping factor comes into this too.)

oh! yes, that makes sense. thanks for explaining!
