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!
Tiptoes vs rubber bottle stoppers: When?
I have a Sony SACD777 that was on one side of setup on a very solid cabinet. Then I moved it to a rack, not so solid. The bottom faded after the move... Tried tiptoes, naaah. Then put size 10 rubber bottle stoppers under feet and WHAM, back comes the bottom stability and "solid" musical bottom end. So??? the question is, what general guidelines does one follow? (besides: what sounds best!!!) and does anyone know the correct amount of weight for a #10 stopper to maximize the vibration dampening properties? and how about a #8 stopper? (I got mine at American Science and Surplus 10's for $1.25 each and 8's for .80...) I use some AQ sorbothane pods under my preamp too.
