Have you tried the most simple but most time-consuming test: unplug all cables?

First set: Have only power amp and speakers working? Is the whine still there?

If not, plug in one more cable. Continue and: When does it start? And then it still might not be that certain cable. It might be a combination of cables that only starts to induce said whine when the last one is connected.

If yes: The source of the whine is something that affects either amp, or speaker cables, or the speaker itself. Maybe it is only a bad connector.
