Cartridge ISOLATION; What Say You?

My arm/arm-board/plinth (70mm 7 layer JVC) are solid, thus I believe all groove/stylus vibration is going into the cartridge;

Then either they stopped teaching basic physics in high school, or you slept through it. Newton, for every action there is an equal and opposite reaction. What you describe is impossible. Never happen. If it did we could not play baseball, tennis, drive cars, on and on.    

The reason the stylus vibrates in the first place is the record groove hits it. Therefore, equal and opposite, just as much vibrational energy goes into the record as the cartridge. Equal and opposite. Are you sure you never heard this before? Just checking.   

These record grooves by the way, they are at right angles to each other which means each side is 45 degrees to vertical, which means Ralph is wrong all the vibrational energy is not in the plane of the platter.   

If you want to try gaskets and duct tape be my guest. Right now on the Tekton Owner's Group on FB there is a guy thinks it funny to use jumper cables. So har de har har. Knock yourself out. When (if) you decide to come back to reality and learn something I will still be here. Who knows if I can set aside the BS might even answer another question or two.   

The reason the stylus vibrates in the first place is the record groove hits it. Therefore, equal and opposite, just as much vibrational energy goes into the record as the cartridge. Equal and opposite.

Conservation of mechanical (vibrational) energy is not a law, but conservation of energy is. Therefore the vibrations are not necessarily equal.

What part of f=ma do you need help with?

there's no need for you to take every opportunity to prove ....

I was letting you know my plinth is solid, and currently nothing else (above the cartridge, or under the tonearm base) is moving. You knew what my point was.

I agree with Chakster, Lew's thing is UGLY!!! And too thick!

I'm also wondering about the adhesive sheets that sound proofing car audio installers use inside door cavities.

for the stylus to read the groove "successfully" the whole system of..........floor, rack, shelf, plinth, platter, tonearm base, bearing, arm wand, cartridge plate, and screws need to be tuned together. each step has to be right......if one step is wrong, then things are off.

what is ’right’? i’ve not seen high end quality cartridges designed to be loose on an arm. not saying it can’t be that way, just never seen it with over 10 turntables, 20 arms, and 30+ cartridges over 30 years.

the best performing systems are solid where they are designed to be solid, and agile and resonance minimizing where they need to do that.

some cartridges even perform better with cartridge screws torqued to a particular spec. i could totally understand that. i recall when Joel Durand was in the early stages of designing his tonearms and he would bring them over to my room to test, he experimented with a number of headshell/cartridge mounting materials and methods. never was ’loose’ or "cushioned" a part of them.

throwing damping products at cartridge mounts is not a direction i see as productive. but might some situation benefit? i suppose i have to keep my mind open. but my sense is that sort of approach is a band aid for some issue elsewhere in the system.....or flaw/compromise in the cartridge, tonearm or turntable design.
