AV Racks. What difference does it make?


Im not sure i understand what difference your rack could possibly have.

I understand everybody here seems to feel that reducing all sorts of vibrations is important as well.

How is that? its not like 1's and 0's get rattled off the circuit board by vibrations

Whats the point in a better rack? What is a better rack? And how does a $1,500.00 rack make anything sound better? I mean, technically, in depth, can anybody explain this phenominon?

Sounds like a buncha horse pucky to me. Kinda like the kinds new clothing.

Does anybody have a theory of how one AV rack can sound different than another? And dont give me any of that room accoustics stuff, i dont see people talking about which sitting chair is best for sound!!!! :)

"I found that wearing wingtips and khaki shorts really opened the soundstage compared to my nikes and TH bluejeans."

I have a good understanding of electronics and accoustics, but i cannot imagine any way a rack could make a difference.
What is the theory of how a Maplewood rack might sound better than an oak for example?

Do you all use racks and isolation pods at the same time?

Thanks for all the responses! Thats what i love about this place, if there is something i dont understand and ask about, i get some very educated and well put together responses.
Hey TWL, you dont need to get so butt-hurt about it, i was wondering why people have these racks that is why i asked.

And research is exactly what im doing now. Why else would i ask? Is this some kind of hobby where you have to go out and learn everything yourself to be a true audiophile or something? If so, hold in, i will go get an engineering degree real quick. Am i not supposed to ask questions and get tips and advice? isnt that thge point of forums?

Sheesh! lighten up!

So,
What i see is that vibration affect turntbles and tubegear more than anything else. If i stay away from tube gear and turntables (which i plan on, im going to stay SS for the time being, might go for tubre and turntables later down the road) then i should not have much to worry about eh? But it would probably be wise to build a rack out of maple? (i love bulding furniture, some day im going to have my own furniture line)

Im buying a new house soon, my existing gear is probably going to be a living-room HT type setup, in the basement i plan on building a dedicated theater once i get it finished, and i plan on eventually getting a 2channel setup in the loft/art-studio.
i get my best inspiration when i am listening to music and in an open space.

I dont think i will ever really worry about getting a really high quality rack untill maybe i have a dedicated listening room, but that will probably be another house later.

i really dont think i can ever get as far into this hobby as some of you. I like the great gear because i like the way the music sounds, but i really dont need "Perfection"
I guess im more of a Tech-file or a Gear-head than a true "Audiophile". I love hardware, i love technology, and i love seeing and hearing what cutting edge technology and craftmanship can create.

thanks for all the great responses! Lotta educated 'files on this board.
Stehno,

Im pretty sure he was responding to me, there was another thread about AV racks, i started this one because i thought my question would be a little too off the point of the other thread.
I think i offended TWL in the other thread, in fact, his response to me in the other thread was quite nasty.

Im not too concerned about it, as even though TWL decided to get all offended and take things personally, i still got a multitude of very well put together responses. Im still not too sure how much credit i will give a rack to the sound quality, but apparently there is some credit to be given, and its nice to understand the theory to how the rack affects the sound

Regardless my question was well answered. And i will continue to ask more questions because i know i can count on the people at the 'gon to give good answers

Yeah. i might be younger than alot of people here, and i might have only really been into the hobby for the past 6-7 years, and only financially able to play in it (ex military) for the past couple yearz, but im definatly not stupid. I will not let somebody else's crappy attitude deter me from learning more. :)

Anyways, Thank you for your responses as well Stehno, you sure seem to know alot about this stuff! :)
I think im going to try making an AV rack using Maple and seismic Bolts. A nice 200LB job.

I dunno if anyone has used sseismic bolts, but they can be bought at any telco harware store like Greybar. they are supposed to supress vibrations against earthquakes, im curious how much they do to prevent vibrations from the floor.

Has anybody ever messed around with various types of suspension to see if they can eliminate vibrations? I dont mean little rubber feet and stuff, but used car shocks, or tension springs, or maybe even some type of neumatical or gell based suspension system?

What about Dynamat? they used that to eliminate vibrations in cars. Ill bet that stuff would make a pretty wicked isolation pad.
Thanks Sean, however, i think i have made my mind up, because i think i have the perfect solution for an AV rack

Get a bunch of paint-mixers and place the audio equipment into the clamps of these babys and turn em on!

they will be shaken so violently that no airborne vibrations will make any difference!:)

HAHAHAHAHAHAHAHAHAHAHAHA

just kiddin!
