Sorry guys – our algorithm designers are only human, and want to make the very best sounds that they can. As a result, they tend to use all the power that is available.

We could say, do half the best you can, and only use half the power, so we could run two algorithms. And, they'd probably quit. So we don't.

Or, we could install twice the power it currently has, and have to increase the price a whole lot. And nobody would buy it. So we don't.

So, alas, there are reasons why things are what they are.
