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.
Just curious, given that you believe that all class ab amps should sound the same - what amp do you use and how did you make your choice? was it simply based on topology/class preference and then determining how many watts would be sufficient for your listening levels/space?
