Just get some Herbies footers. They don't cost much an are very effective. Much better than the stock footer. I also own BDR pucks and cones which have their place as well. So if you can't find the original footers I would go for Herbies. You can use 3 if you want and put one directly under the transport and the other two close to where the originals were.
Where can I get components footers ?
I bought a Denon CD player from an AV installer and he threw the footers away because this particular CD player was supposed to be used at a University bolted to a rack. I've taken the rack bracket off the CD player but it is sitting on it's belly now. I called Denon and they don't have them. Any idea where I can find something similar ?
