Feets for cd/amp/speakers????

[Per Nielsen]

Is there any body who has some ideas, how I can make my own feets for my cd player/amp/speakers any body who has any experinces with this?? Im thinking on rubber feets or spikes but I dont know how to make them, or what material to make them of

Per Nielsen, forgive my opinion.

Don’t you think that there are many better things to do to improve our system other than experimenting with CD/amp/speaker feet? Speaker feet may be the most significant, but you will really have to experiment (no formula here).

This opinion comes from my experience in the old days. For example, I’ve learnt that I don’t need to waste my time experimenting with capacitor types in a certain circuit location. Well, may be I have got the trick from the stupid experience

Depending on equipment you have, but proper feet might have big influence on the sound.

If you want to go with aluminum feet, you can use 3/4 or 1" rods and cut them to desired length ataching rubber at the bottom. Old knobs can make nice feet as well, also acrylic. If you using hard matrial for you feet, whatever soft material you put under and the thikness of it will infuence sonics. I found that brass spikes work pretty well, but final result depends on the surface they rest. Don't assume that feet have to be round. Nothing wrong with making them square.

Don't underestimate importance of proper equipment placement. I can almost guarantee that if you take any $10,000 unit (eiter CD, DAC or preamp) and not place it properly, you will get rather mediocre results and the full potential won't be achieved.

Jay im sorry to say this but: YOUR WRONG!!!
I have just been to a hifi convention where a guy proved to me that there is a large improvement on this area, he yoused springs for suspension on his cd player, I did belive the same thing as you Jay in till I heard his cd with springs and with out .

Whats is best metal spikes or a soft kind of feets???

It all depends on overall setup: the unit itself and supporting platform. Sometimes 3 spikes work well. sometimes just one in front and 2 rubber feet at rear. I prefer brass spikes to steel. You just have to experiment. And Mrfeedback is a great proponent of springs. The harder the suspention is the more bass you get. With softer suspention highs and mids are better, with possible increase in depth.

I'd suggest that you check around in automobile stores - certain types of bushes make very good equipment feet. Generally rubber used in the automobile industry do not deteriorate in oil and some of them just have the right hardness/softness. I have found a rubber bush that fits on the underside of a bike exhaust, acting as a stopper for the centre stand that make excellent feet; this particular feet requires a hole of 10mm dia into which the grommet like portion is pushed in and the actual feet is about 22mm dia and 22mm height.

The main concern should be to reduce transfer of vibration from and to the equipment. Yes, as Peter says the platform is just as important; whatever be your platform, try to place a coin between the platform and the tip of the spike that your equipment is resting on. It does wonders to the sonics.

You will have to experiment extensively in this area, as one measure of enhancement in one environment does not guarantee the same result in another environment.

You will find a lot of diy stuff in audio-tweaks; however, I do not know the url for this site. May be someone can help in this regard.

Well, good luck Per Nielsen. That is how the DIY world has been going on for years. BTW, I like the look of NAD stuffs, so I hope they will release their spring suspension CDP soon

I love bike inner tubes. Tried 16 x 2.125" under my CDP. It gave me more detail, dynamic contrast & more pinpoint & layered soundstage.

Per,
As peter mentions, I have had VERY good sucess with automotive engine valve springs.
These can be obtained from your local engine rebuilder or wrecker for free.
These springs are about 4cm diameter, and the tops and bottoms are ground perfectly flat.

I place three under each component and speakers, and find I am getting very pleasing resultants that gives lower lows, nicer mids and better imaging than my experiments with feet, spikes or cones.
