Isolation Advice Needed

@retiredfarmer _hey farmer- I did something similar- two sheets of marine ply, with glue and a barn mat. Still didn't fix footfall issues in an 1880 house in downtown Austin. I respect farmers, rednecks and all people driving pick-up trucks for work. :)

I was able to hammer two vertical beams into place in the basement so they support the wood floor in our living / listening room, beneath the rack and speakers. Result: we can jump in front the player without the cartridge skipping, and have no problems with footfalls, dancing, gym, etc. Probably my best feet/damping/platform investment ever.

Thank you all for all the great suggestions.

Best Regards

I'm a big fan of Townshend audio isolation products.  Effective isolation of each component can get expensive.  I use the Townshend podiums on my speakers but they have "seismic corners that can be used on an equipment rack.

Let me say this: If you don't have a well supported wood floor in the first place underneath your house, then adding layers of weight (read more sag) with whatever type of flooring material will likely be in vain. 

 I know that there are other issues of concern with a concrete floor, yet it would be my preference to deal with.
