How do you deal with vibration?


Greetings all,

Many of us work very hard to keep vibration out of our equipment. I was hoping we could share our experiences with each other. I was wondering what other DIY methods people are using?

I personally have had good luck with shipping open cell foam under plywood. I find that about 60-70 percent compression works best. I place the foam underneath some plywood (Using spruce 3/4 inch). Then I place the component on the plywood. However, I think this more isolates the component from outside vibration. I don't think it does much to drain internal vibrations, especially in a CD transport.

Also I can not find open cell foam in town any more. I am ashamed to say that I actually went to Wal-mart to buy some. Now they don't carry it any more. So I was wondering where else I can get some?

I am currently thinking about building a Sandbox for my CD player and amp. Then putting the sand box on top of some sort of isolation material (open cell foam or cork rubber etc.) My thoughts are the foam or cork or etc should help keep the vibrations from getting into the equipment and the box should drain the internal vibrations.

Also, what are peoples experience with different woods. I live in BC so I can get most wood fairly cheap. I imagine every wood has it's own sonic signature due to it's resonant frequency. What works best? Solid maple, birch ply, MDF, walnut, mahogany etc...?\

Anyways, feel free to through ideas and experience (both good and bad) out there. It would be good to know what works and what doesn't.

Happy tweaking,

I choose to write a separate post for this comment. I was thinking last night about how to equate this thread to some other topic. I came up with fruit. Let’s say three of us are discussing the sonic qualities of our systems. Now let’s equate the sonic qualities to the physical properties of the inside of fruit. In both cases none of us ever explain what our system is (or in this case explain what fruit we are holding.) In my case I have an apple, Nickway has an orange and Eldartford has a banana. I explain that when I cut my fruit it’s crisp and juice. After tasting, it was sweet with a tinge of sour. Nickway doubts my findings and posts a nasty comment stating that I had no idea what I was talking about because the inside was juice like mine but clearly not crispy. He did however agree with my findings of taste. Now Eldartford writes in and slams both us because his is not crispy or juice, his was mushy and soft and very flavorful but neither sweet or sour.
You see the point; we all have completely different fruit. We all are right; but we discount the others comments because they do not have the same characteristics. Well, if we try to explain the effects of vibration control on our stereos, and not discuss the components, we will be arguing over nothing rational, and advising when it’s possible my findings will not match someone else’s. In the case of this thread, Eldartford has a nice entry level system. (Please do not take offence) and Nickway has a very strong middle level system. I have a low/middle high level system. I’m trying to share my many years of experiments in this area of vibration control, yet my system is extremely sensitive and thus my findings may not translate to Eldartford. Again no one is wrong, we all have had these experiences as we describe. It simply can not be assumed that each of us will have the same result. On top of this, each of us has strengths and weaknesses in our systems. What I consider a strength may not be what Nickway sees as a strength. This is why I feel strongly that we share real live experiences and trials of our tweaks, and not discount the findings. If we share experiences, and put it into context by looking into each others system as listed on the Audiogon system section, then we are able to draw our own conclusions. The only thing I know for sure is my apple is not mushy and soft.

I've decided that everything is imagined, even that I'm imagining.

So therefore, since everything in "reality" is imagined, it matters not whether we are imagining it or not, because everything we know is imagined. Even double-blind testing is no answer, because we could be imagining that we are doing double-blind testing, and imagining the results, and imagining that we are typing the results on the page.

Now that we've established that since I'm imagining my audio system, and that my system sounds better when I buy a new component, or put some cones under it, or use different cables, then it is quite ok that I'm imagining that it sounds better.

And there's really no cost to anything because we are only imagining that we are paying for anything anyway. So, buy anything you want no matter what the cost, because the money is imaginary, so spend to your heart's content.

See, it actually is simple.
You can never "prove" anything, because no matter what you do, you could be imagining it.
This only becomes a problem if one needs to live in a provable universe.

I'd rather take the Algonquin Round Table, United Nations, or ecumenical council approach.

We all weigh in, let the questioning poster sort it out.

Excellent overview of the two different mind-sets and their attendant concerns.

>>The original post here concerned how do people deal with vibration, not whether it is meaningful to do so.<<

True, but when a topic like this comes up, others lurk or peruse the thread as well. I think it is useful for people who come to this forum because they are interested in audio to know that there are people here with different philosophies and approaches. Otherwise, it would give the false appearance of a concensus around things like expensive cabling, vibration control, etc.

I think we're a better forum if people interested in audio know that there isn't any such concensus among audiophiles, that these topics are controversial at best, and that there is a place in this forum for skepticism, that it isn't a "church" for believers only. I think the "church" approach would make this forum weaker, less inclusive, more limited in its appeal.

I don't think we want that.

At least, I don't.
Hello Jadem6,

Thanks for your help with this. It was good to discuss it with you. I am hopefully going to make a few platforms this weekend. It's always nice to get advice for someone who has experimented before (plus you have a resolving of enough system to be able to get a good idea what works.)

And don't worry, I don't take offense to my system being called middle of the road. I know where my system stands. Audio/music is my passion and all that stops me from having the system of my dreams is a few zero's at the end of my paycheck.

I could go work a job I hate and exploit people to make more money, and while it my be legally acceptable I don't think it's morally acceptable. So I purchase what I can afford, which lately is not much (I got married two years ago and bought my first house 1 year ago.) Maybe one day I will own a $15k+ system but not any time soon (unless I win the lottery). For now I am going to continue to enjoy what I have and upgraded it as I can afford too.

Happy listening,
