When you came to this forum and espouse unsubstantiated myths and folklores, be prepared to be challenged.
Here is part of what I quoted in Dr. Toole's post in AVS Forum in post #172.
WOW ... that is REALLY impressive. It is, amazing insight and understanding ...
So here's the scenario...
Our Typical Audiophile is out looking for a new pair of speakers.
He's in the showroom listening to the latest Acme Mark7ProPlus Deluxe.
How does any of that help him in the least?
Really how does he use your amazing insights to decide his purchase?
My Gawd here's a simple thought ... put you hand on the back and see if it's vibrating!
Between a speaker with vibrating case panels and one without... I'll take the one without every time.
This morning I was all set to just log out and walk away from this place.
You guys are seriously out of touch with reality.
Even Amir with his magical AP Analyser appears to have missed a couple of serious design flaws in the Topping products.
I'm a 40 year experienced technician with about 10 years of design level experience... and I can assure you that while this level of highly esoteric insight is very helpful in designing speakers or amps it is no more useful than fresh shit on a sidewalk for the average person who's trying to decide what to buy ... and isn't that the goal here... to help people decide what to buy?
Y'all need to pull those craniums out of your rectums and have a good look around from time to time.
The world simply does not work the way you seem to think it does.
