Brass door knobs as footers

Actually, the Mapleshade brass heavy footers come in at $160/set of four.

Here's an in-between compromise: *adjustable* solid brass footers from Parts Express for $71.45 for a set of four.

Another A-goner has these and says the threads make these footers direct replacements for the stock Technics SL12x0 feet. These are on my short list.

I love a bargain, myself.
I think the idea with the footers is to drain internal vibrations into a very small foot print so there's not a lot of area to conduct vibrations back up into whatever the equipment is you are trying to isolate.

I do think the knobs might work. Seems to me (without actually seeing the knobs you are considering) you might still have a broad contact area, however. Check out Parts Express and look for Dayton Speaker Cone Spikes (or some variation on that). I used 4 of these (~$30 with shipping) and a 2 1/4" Cuisinart wood chopping block (HEAVY!) from Lowes to make a bargain plinth for my turntable. Actually think I hear a difference. Hey - either way, it's worth the experiment.

Home Depot, they have all kinds of cool knobs and stuff like that.
