A cheap fix is to get some wheelbarrow inner tubes and place them on your horizontal surface, then put a cement block or slab of wood on the inner tubes. On this you can set your turntable. I learned this trick in graduate school where we needed a vibration-free platform to damp out building vibrations and our research group didn't have any money. Your woofer pumping issue is another problem that probablly is due to a mismatch between your arm and cartridge. There is a lot of discussion on this forum about fixing it.
What If Wall Shelf Isn't Option For My Turntable?
Hi Everyone,
My turntable has always worked fine resting on a thick piece of plywood situated inside one of those 4-level metal shelf furniture gizmos.
I've changed to a much more powerful integrated amp, and my Vandersteens are VIBRATING when at normal listening levels - they look like somebody shivering out in the cold.
My domestic situation dictates that the turntable be close to the Vandys - something like 18 inches away from the left speaker, and maybe another 18 inches above in the air.
I also cannot install a wall shelf.
Is there anything that can be done to eliminate this feedback problem, barring going back to the old integrated?
I've read about suggestions of sorbothane, cutting a piece of granite, vibrapods, and whatever else, but I have no idea where to begin or what to try.
Any help at all is greatly appreciated - thank you!
