The same about thermal effects: application of voltage increases their energy similarly to application of heat, and vice verse. Heated carriers jump over potential barriers causing electric current.

All of the Parasound designs are made with automatic assembly. Yet, we don't have the problem.

Good choice: both examine similar, but different enough topologies in details.

So global feedback while lowering thd increases propagation delay ...?

I recommend that you, tvrgeek, buy both authors books, along with 'The Art of Electronics'. Go through them, and then you will know what they know. Then we can proceed from there to solve these specific problems, well known to several experienced design engineers on this website.

I would say, it causes modulation of propagation delay.

No, not really. Handwaving doesn't work, either.
