Funny, I haven't heard anyone here talk about food tweaks so let me enlighten you fellow twerkers if you haven't tried this yet:
Creamy Peanut Butter: Take 2 to 4 jars of JIF or Peter Pan put it in a large ziploc bag and place it underneath your cd player or turntable to deaden any vibration
Granola Bars: Take Nature Valley Oats n Honey granola bars, cut them up in 2" squares, stack them up with Nutella in between, wrap them in saran wrap and place under speakers or components instead of brass cones or other materials.
I also use 6 pieces of granola w/nutella in between as cable risers - 4 pcs of Granola stacked up and 2 pieces on either end so it is "U" shaped with Nutella in between to hold it all together and then I lay the speaker cable in the trough. I then use Nutella to keep the speaker wire from moving.
Saving the best food tweak for last:
M&M's and York Peppermint Patties: On the 1st and 3rd weeks of every month I put plain M&M's on top of my speakers to spell out the words "I need sex"...on the 2nd and 4th weeks I replace the M&M's with York Peppermint Patties because I have felt the sensation.
