Ozzy:
I have no first hand experience with the 2 spiked racks I suggested that the OP research.
They were the only two inexpensive "spiked" designs that I came up with on a quick Google search.
The big hitters, when I was researching racks 20 years ago, were Symposium, Systrum (sp?) and Solid Steel.
There's another one as well, but I'm blanking on the name.
My main goal (@ the time) involved adjustable upturned spikes for each shelf and lighter weight (though rigid) construction.
Looking back I really only required the adjustable spikes for leveling the moving parts source gear.
I prefer to use the original footers (or something very close to that) on my TT/CD deck and the Neuance shelves.
I gave up on specialty footers long ago as the various designs SO GREATLY altered the sound/sonic balance of my source gear to the point that my Thorens and CAL were barely recognizable as being Thorens/CAL sound wise.
They were designed with stock footers (Thorens and CAL knew what they were doing, IMO) and the Neuance shelves maintained their "house sound" while @ the same time improving upon it.
My main problem with both units was the bass/midbass, and this was remedied, to my satisfaction, with the addition of properly implemented specialty shelves.
By the way, I used real speakers back then (you know with woofers/tweeters/crossover;-).
