Turntable suggestions for a shaky wooden floor

I have a listening room suspended over a two car garage and had quite a time getting vibrations under control. What I did was this:

1. Very heavy Timber Nation 4 Shelf Maple rack with spikes at every shelf support...

2. Iso-Pucks under all equipment.

3. 9 large 4" thick bass traps..two corner and 7 wall

The isolation table suggested above is a good suggestion. I would not buy a new turntable and cartridge unless you were going to spend a good bit more...and my suggestions above would cost many times what you want to spend on a turntable..so isolation table and Iso-Pucks where needed are the way to go, or relocate your listening space.  Also, people use wall mounted turntables to overcome this sort of issue.

I hate to mention this, but for the best "bang for the buck" used digital is probably the way to go. I say this because I had to spend four times the amount on my analog gear to get it to sound better than my digital equipment.

No carpet I’m afraid it’s all hardwood. Thanks for the input all.

What benefit might there be to a large carpet with thick padding? This and a full size sofa were my first room treatment, but they predated the arrival of any of my components, so not sure how they changed the listening environment.  I know that this won't solve your vibration issue, but it might contribute to a solution.
