Every day I see another turntable recommendation...

@clearthinker , no wonder. I owned two Linns over the years and they have to be the poorest suspended turntables made. Very unstable. The problem was they were a great sounding turntable for relatively reasonable money at the time. I got rid of my last one in 1981 and never looked back.

False clearthinker. There is loads of low frequency noise in the environment that is transmitted to the turntable. Don't believe me? With your turntable on, place the stylus down in the run out area and turn the volume all the way up. Keep an eye on your woofers. Have a friend or significant other turn on the washing machine and watch what happens. Have them walk around the room, jump up and down. You will hear your furnace light up and your AC compressor start up. You might even hear cars going up your street. A severe earthquake is just visible evidence of a wave traveling through the ground. The earth is quaking all the time at levels you can not feel, but your cartridge can and if you have a good system you will see it in the woofers. 

Currently, the way my Sota is set up if you do the same experiment, and I have, all I ever get is a little hiss from the phono stage and I have boosted subwoofers. With the high pass filter off my system will go right down to DC. I can hammer the side of the plinth and you can not hear a thing and I mean hard enough to dent the wood if I did not have a wooden block in the way. Try that with your table but you might want to turn the volume down first and be ready to catch the tonearm. Like the earth quake this is a severe example. People do not normally hit their tables with hammers but you will see in your woofers how plenty of noise you can't hear makes it's way into your system via the turntable and it does not matter how much the turntable weights, this is just lay intuition. 

Fine mijo.  If you play records while hammering the side of your plinth, so be it.

Overkill earthquakes, overkill hammering, washing machines, jumping up and down.  We are talking about small airborne soundwaves.

The effects of other activities taking place within a local environment are able to create a transfer of energy that can be detected in a home.

I live in a rural area with neighbours properties approx' 300' ft away from my house.

Neighbours in their homes are not a concern and the activities they are involved with outside of their homes are not a concern, where creating energy transfer to my home is concerned.

Others using HiFi set Ups can be effected by a neighbours activities.

My Home is approx' 60' ft in from a Road, which for a large proportion of a day has substantial agricultural vehicles using it, these are very capable to transfer energies in to the home and are regularly felt passing by, and not only heard. In the Spring /Summer the vehicles operate for a long day, during the autumn/winter the road usage is much less.

The Fighter Jet Base can make the property rattle when the after burners kick in and this is from a mile away.

None of these environmental impacts, concern me during my listening periods, as I am aware of most of the times these will be present and choose not to use the main system, when the impact can occur.

Background music replayed through a simplistic device, is used to supply musical encounters, when the conditions are not ideal, and the music being replayed is totally satisfying.

Choosing a time to listen is what many who enjoy their HiFi systems do daily, if a environment is local that can effect the quality of the replay, choosing periods when quiet is present will be very beneficial, if sitting down when listening, footfall will not impact too much either.

All said and done, a little thought applied to discovering methods that can be used to mount a TT, will also add to ones knowledge and methods learned of might be adopted.          

There is more than one way of shielding from vibration.  I favour unsprung TTs, no added springs elsewhere (boing boing) - who says vibrations can't pass through springs?

Hooke?
