Interesting but not exactly news…
Benchmark also discuss damping factor towards the end of this very long thread:

Not meant as news. :face_with_raised_eyebrow:

Yeah. Though I think the takeaway is that you should use Class-D.

The Benchmark ABH2 is a Class-AB amp with an impressively low 21.6 mΩ output impedance. But Hypex NCORE amp modules (say) have an output impedance an order of magnitude smaller — which is to say, a damping factor an order of magnitude larger.

The result: ruler-flat frequency response into even the most difficult of speaker loads.

But, again, not news.
