hi prem,
i actually went to their site for tube dampers then saw the isocups and stuff. had been there very very long back. very affordable stuff.
the spikes were on the concrete ground directly, and touching the amp directly too. not ideal, just a temp measure. getting low slung tables made for the amp and phonostage and turntable and the isocups for amp, tenderfeet for phonostage and grungebuster dots for turntable feet and motor. ought to be good.
do you think if i get a table made and get the isocups, adding the sandstone slab on top of the table will help? was toying with the idea of making sandboxes for all my components...
just can't make up my mind
regards
Hi Steven,
came across a very interesting article on isolation and vibration experienced by tuntables. It has a very interesting test.
"The first and most important issue to address is unwanted vibration. As we know, the stylus is a vibration-recording machine of incredible delicacy, able to read minute shifts on the order of just a few microns (i.e. you'd need an electron microscope to see the scale it's tracking). Obviously any additional vibrations are going to to be a key source of degradation. One of the most significant sources of spurious vibrations is the room itself and the floor on which the turntable stand actually sits. If your turntable stand doesn't pass the "glass of water" test (that is, put a full glass of water on the shelf beside the turntable and jump up and down heavily beside it - if you get a ripple in the glass then the support fails) you need to look carefully at other options."
I am going to try this water test today. I have to make sure nobody is around because you can imagine what they will think.
Here is the complete article.

Thanks.
hi malvai,
yes a sandbox is quite an alternative if you don't want to spend on a dedicated rack. re the leaking of sand, one can put a plastic sheet and place the top plank so no sand can come out. shouldn't be an issue unless one fiddles around too much too often

But how is one supposed to notice 'little' ripples in glass of water while jumping up and down at the same time."The first and most important issue to address is unwanted vibration.

hehehe... This vibration test is too good and tempting not to try. To save embarrassment will get a fat guy from my building to do this while I watch the glass water, will tell him future of analog sound reproduction is depended on this test..... :lol:
Thanks malvai,Just suggest this very very tactfully...
Hi Stevieboy
I had the Brightstar sandboxes long back. I think you should try the sandstone slab. Take a 3cm thick slab. It should cost you about 300 bucks. Do not have it polished. I would personally prefer the equipment with the Herbies footers directly on the sandstone slab and no wooden platform underneath the slab
