Tiptoes vs rubber bottle stoppers: When?

First the use of bottle stoppers might "stop the liquidity of the sound".......
Joking aside be VERY careful with putting oil into inner tubes, oil might degrade the rubber and the potential mess + spill on electronics might be terrible !!!!!!

Liz, do you know if stoppers were molded or extruded and sliced? I have heard it matters in terms of removing unwanted audio resonance. If the pods or stoppers or feet attachments are extruded as one piece then sliced (hence horizontal orientation and strands that when laid flat become perpendicular to shelf and compontent and act as conduit to detrimentally transport resonances vs a random extruded design with an "across the grain" configuration) it does perform as well as molded wherein the strands, actually cells, are random and multidirectional, qualities that ensure soundstage air and depth and directly translate in both bass speed and bass weight while not effecting the mids and often improving the highs. You should see previous discusions of topic on AA. Let me know if you find out from manufacturers about your stoppers orientation. Have you thought about a DBT? Good listening!

Try some Vibrapods; they're quite inexpensive & you might be very pleasantly surprised. They are spec'd according to weight loading (re: your question above). I try to use them at the midrange of their specified weight capacity. Different values of their #1's thru #5's can be combined in various ways too.

The stoppers are clearly seen to be molded and not cut from a larger tube. (i make sure I get new 'soft' ones and not old 'hard' ones too.) On buying some "oficial" footers just because they are 'authorized'???? I HAVE all sorts of footers,pods,wood blocks,tiptoes etc... the bottlestoppers work damn well, and the cabinet IS the problem, but as a solution to the cabinet problem, the bottle stoppers seem to do just the right thing. (the cabinet vibrations before the rubber addition seemed to have cancelled out the players solid lower mid and totally wrecked to bass. WITH the footers the player was BACK to the sound it had on the really solid foundation.

Glad to hear that a cheap fix works for you. Every component does not respond the same. When you have to factor in all the component/shelf/stand/flooring variables you just have to "play it by ear". Love it when 5 dollor stoppers work better than expensive feet. Good job.
