Using protective discs under brass footers

Just did. My new amp has inverted cone feet. Bought some relatively inexpensive cups - metal with rubber, about 2" round. Purpose was to protect the wood, but low and behold, the midrange opened up, more air etc.

Who would have thought.

I have been a Star Sound dealer and their brass cones do sound somewhat better using the matching brass saucers. Not night and day but noticable.

I can't believe using those disk's will get the job done that the footers were intended to do.
I use maple platforms on my maple shelves with those rubber/ cork isoblocks between them. Then the brass footers on my component dig into the platforms instead of the shelves. Now there will be those footer holes only in the platforms instaed of your rack shelves.
Works especially well for my turntable and amp.

Markpao- Think you should have bought some addtl maple shelves to protect the maple shelves that are protecting your rack's shelving! Just joking. Wish I could afford your setup, but I could barely afford the new rack. I just took delivery of Bearpaws for my VPI Classic from Eden Sound and have a lot of Audio Points sitting in my drawer. When my rack arrives, I'll definitely have to do some testing.

I have a friend who uses Audio Points and a Mapleshade Samson rack; his gear sounded better with the saucers but if I remember correctly we used them point upward with the saucer under the component rather than downward into the shelf. You can try the Audio Points either way, they will sound different; one gives more coupling; the other more isolation. This is of course not an option with something like the VPI; the Star Sound brass cones made a significant improvement on it and I would expect the Bearpaws to do something similar. I used the saucers under it also but if you are just worrying about shelf damage you could used a government approved copper disc; AKA a penny.
