Aren’t the two main transducers, speakers and cartridge, the most important?

I first was interested in Townshend Seismic Podiums by reading many posts of users raving about them. Then I was convinced to buy them by watching the above video!
The stick with the small motor attached on top sitting on a podium and an identical one sitting on a platform with just spikes.
When turning the motors on, the difference in the movement of the sticks is radical and obvious. The podiums kill the vibration.
The result in SQ is also radical and obvious.
I have used hockey pucks under components and speakers. And still use them under the spikes of my rack. The difference between pucks and podiums is also radical and obvious. Posts that make comparisons without actually having experienced the criticized item are disturbing.

Regarding transducers: surely I was impressed by the difference between my $3K cartridge and my new $13K one. However, it also made clear the importance and central contribution of the cartridge.
The role of the two transducers, cartridge and speaker, clearly are foremost in a system. The cart taking a tiny vibration and translating it into an electronic signal. And a speaker taking that electronic signal and turning it into sound. Surely, the up line/down line components all greatly contribute. But we would have nothing without the physical/electrical-electrical/physical process of the transducers. To describe from a lay and outline description.

Looks like  someone got "schooled."

Maybe a trip to the wood shed.  :-)

Only speakers can change the radiation pattern of sound.

For those of us that enjoy something other than usual box speakers e.g. open baffle, omni, dipole, bipole, wide dispersion, this can only be created by the right speaker.
