In any case, Hegel is just like most other audio manufacturers - they'll brag about some specific parametric or other and claim *that* is what makes their amp special. And many will believe it.
Damping factor is generally a non-issue with solid state a/b amps. They're all high enough that it doesn't matter. Certainly so with a speaker like the Sierra that doesn't have ridiculously low dips in its impedance. Damping factor can be an issue with tube amps and class d amps, where the output impedance is often much higher.
Keep in mind that when you're testing amps sighted and non-level matched, you're not really just testing amps - you yourself are now an uncontrolled variable in the test. You're testing yourself and your brain as much as you're testing the amps.
