How to best isolate TT from vibration?

Hi all:

I'm currently using a Systemdek IIX table, which has a floating suspension system. I have it on a Atlantis Reference rack, but have replaced the top shelf with a 18" x 18" x 2" brick paver, and use (8) Vibrapod 4's under the table itself to prevent vibration. I still suffer from some skipping unless I walk ever so softly in my music room, most noticably at the beginning of an LP. I'm looking for input regarding what you fine members consider to be the best, but yet economical, methods of isolating this table and nixing this problem. Thanks,

Jim

Assuming your on a 2nd floor or something similar?

Sometimes a Wall mounted shelf works best for foot fall induced skipping. Also, if there is any way to put a jack under the floor joists, directly under the table that can help. Not sure if you can attempt this one. One other idea is to move the rack to a different wall. Usually a outside wall is best, where the studs go down to the cement.

Just a few thoughts, others may have better/diff ideas...

IMO, your Vibrapods are much too hard. I am not familiar with your turntable but unless it weighs 128 lbs., 8 #4s is too much and they are doing you no good whatsoever.

I would suggest you try some #1 (maybe #2) and I bet that will solve your problem. This is how I eliminated the same kind of skipping in my Audio Aero Prima cdp. Vibrapods come in a range of softness for an extremely good reason!

Wall mount recommendations are right on.

FWIW foot fall induced vibrations are vertical and NO isolation system is going to eliminate them completely, not spring systems, nor isolation devices of any type. Believe it or not unsuspended tables acually deal better with foot fall problems than suspended ones. Think about it a bit and you will figure out why.

In addition to Nsgarch's suggestion, have you considered reinforcing the floor under your turntables rack. Assuming you're on the first floor, can you get under the house?
