How to best isolate TT from vibration?

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!

Can get you a great price off retail.

Wall-shelf. Target makes the Volkswagen of wall shelves --Available at Audio advisor, and other fine audio retailers ;--)

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?

I do agree w/ Newbee's exception: If you have a concrete slab-on-grade floor (or a 1 foot thick steel-reinforced floor in a hi-rise or loft,) then a stout rack (like a Billy Bags) spiked right into the floor will do it (or for the cost of a few concrete blocks and some mortar, you could build your own TT pedestal for pennies!

I also think unsuspended tables are the way of the future ;--)

I don't have Newbee's faith in jacking joisted floors. Which isn't to say that it can't work. It's just that a lot of the existing floor's construction details have to be just right.

Tips about wall shelves:

Mount them on any masonry wall, if it works out OK for you in that location.

Second choice, an outside wall -- heavier studs and thicker surfaces (more mass -- less vibes)

If you're in a new, cheap, tract house, on an inside partition wall -- don't despair. Wall shelves are usually 2 stud spaces wide (16" + 16" = 32") Get a 48" wide (4 ft) by 2ft high by 1" thick piece of Scandinavian plywood (the kind with many pretty laminations, like used in furniture), finish it natural or to match the wall and lag bolt it to four studs (16" + 16" + 16" = 48".) You can mount the TT shelf on the plywood panel with lag screws, but if you're really cool, you'll pre-install T-nuts on the back side of the panel to receive bolts thru the wallshelf after the panel is mounted to the wall. It'll look great and be stiff as a board (did I say that?)
