Tiptoes vs rubber bottle stoppers: When?

Elizabeth; You're probably gonna' have to experiment with the bottle stoppers to come up with what you like best; maybe try different sizes-- a good idea BTW. I think Redkiwi is probably the best source of info. on resonance control. If your thread doesn't catch his attention, try emailing him. He's a nice guy-- and knowledgeable. Cheers. Craig.

Elizabeth: I'd be curious to know how the sound of the bottle stoppers under the existing feet compares to their sound directly against the chassis. Also, some 'philes have had good results using a partially-inflated 12" bicycle (butyl rubber) inner tube between the chassis and the shelf. Bile tubes filled with oil may sound better and provide more stability than those simply filled with air. Perhaps someone else here can suggest the best type of oil to use.

I've tried Sorbothane pucks in my system and have found that generally make the sound smoother and less harsh, but can also decrease apparent system dynamics (though they can work well in some systems when used in moderation).

Oops! My last sentence in the first paragraph of my preceeding post should start with "Bike tubes," instead of "Bile tubes". My hunch is that "bile" would not work well as a tube material. :)

I only have my opinions Craig and Elizabeth, and what I have to say will probably not go down too well in this instance. I don't doubt what you say you hear, or that you preferred the weightier bass Elizabeth. And if I was there I expect I would agree with that preference.

But (and you knew that was coming), as I have reported elsewhere, I have gotten fooled by this same thing, and eventually saw through it. Using heavy shelfs and certain types of rubber footers will add bass weight, but they do this by moving resonance points into the bass region and lengthening (smearing) bass transients). But if the flipside is using light and rigid supports, and having no bass weight (cause the real thing has bass weight), is it any better? Well there are some solutions that can give you bass speed and bass weight. There may also be iisues with the rack you are using Elizabeth.

I know I am suggesting a u-turn from the path you are on. Do a search on "Shelf" and you will see how much I have been ranting on this topic. But perhaps something you may be happy with is a suggestion you use the E-A-R feet, which give a good bass result while retaining good articulation, and which I reckon are overall way better than any rubber foot - they are a polymer of some sort, look like a rubber footer, are not very big, come in two sizes depending on weight of the component (and you must use the correct size for good results) and are cheap.
