Suspensions on turntable...really effective?


Been wondering about this, so did some research, but was surprised I couldn't find any that categorically says that turntable suspensions really isolate/substantially reduce outside vibrations, resonances, etc.

Any reference out there you can point out?

Is there any TURNTABLE out there where I wouldn't be able to hear the unintended taps, touches and bumps on the rack and sound/vibrations from my subwoofer?

Cheapest you can recommend please?
"Every low level signal phono cartridge consists of key components: the stylus, cantilever, MAGNETS, coils and body. What are we going to now GK......you better go tell every cartridge maker about this."

Uh, it’s the size/strength of the magnetic field the mag lev systems produce that’s the issue. And the cartridge is in close proximity to the Verdier magnets, that’s the problem. Hel-loo! I’m not concerned about the Earth’s magnetic field any more than the cartridge magnetic field for that reason. Why do we have demagnetizers for LPs but not for the mag lev magnets?  ;-)

For suspended turntables the reason vibrations like footfalls and other vibrations are audible is because the turntable’s suspension’s resonant frequency is not low enough to block or attenuate them. If the turntable is unsuspended it should be placed on an isolation stand of good design. For suspended turntables with issues remove the suspension and place the turntable on an isolation system of appropriate design. For turntables like Verdier and VPI and Raven and other big heavy turntables one need look no further than my new Super Stiff Springs, which are designed to isolate and support just about any heavy object under the sun. Just the ticket for subwoofers, heavy turntables and heavy amps; minimum weight 75-100 lb. For things like CD players, headphone amps, preamps and other moderate weight components I have a different softer spring, the Cryo Baby Promethean Mini Isolator, cryogenically treated high carbon steel compression springs.

GeoffKait, could you please explain how the Super Stiff Springs can effectively prevent taps, bumps and vibrations from subwoofer?

Its resinant frequency is low enough, 0.5hz?
