Background vibration and your system.

I have been interested in vibration and its effect on my audio system for probably forty years. I remember getting some platforms with inner tubes that had to be pumped up with a bicycle pump very early on. Well, I think they may have helps a little... but pumping them up drove me crazy. Since them I have used pucks of all kinds, and Black Diamond Racing composite platforms and cones, springs, and the best has been the Silent Running Audio Ohio Class vibration platform that I had made specifically for my Linn LP12... which was well worth the price. 

I used to be a geologist. So, I have wanted to get a seismograph for a long time. About a  year ago I purchased one. It is on the Raspberry Shake network with thousands of others. They have confirmed the correlation between times of day and remote events being transmitted into the house. Evenings and especially Sunday nights tend to be the quietest. I have seen thunder claps, cars and trucks driving by being recorded as well as not too hard footfalls on my concrete floor.  

On the map below, you can see the Pacific Northwest. Each icon is a seismograph that can be viewed.  The red dots are small earthquakes which can be seen and correlated with the recording of any of the seismograph by clicking on a red dot and then the seismograph. This page has a tremendous amount of different functions if you just explore it. 

I recommend folks that are interested, move around the map and find one close to your house. You may be surprised how much activity there is.

Studio monitors have a very different purpose and setup. They are made for near field listening and not for nuanced wide soundstage projection. Audiophile system are far more sensitive to inputs. I am sure if you took two self powered studio monitors and put them on stands in a listening room and fed with audiophile sound feed... well, that would be a whole different sound entirely.

You can really knock yourself out comparing vibrapods, all the different elastomer pucks, cones of different materials... etc. I have a couple drawers of this stuff. I spend probably hundreds of hours or more doing detailed comparisons over the decades.

A very generalized conclusion I came to is that the very expensive stuff... like Townsend, Silent Running Audio, and Black Diamond work better than cheap stuff. It’s really simple, companies like these that do Research and Development can/must produce products that are very notably superior to someone who simply chooses a substance and makes it into a form. Companies like Townsend and Silent Running have outstanding reputations for a reason. Folks that can afford them hear the difference. 

I was young and poor once and worked my way through inexpensive alternatives. Nothing wrong with that.

Thanks for your interesting post. Great problem... I love challenges like that. Sound like fun.

You know Silent Running Audio... started with platforms for scanning electron microscopes and submarines? I don't know that much about them, but love their platforms.
