Audio Rack Shelves?

Mechanical isolation and its audible effects can be scientifically verified. If your equipment is resolving enough you can easily hear it

Just caught up on this thread...

Well you are not alone my friend. But this very uncertainty of yours is what helps the multi billion dollar audiophile tweaking industry grow stronger every year.

How about this for your next upgrade?

If that hasn't impressed you, there are many more "ideas" to make ones hearing ability esoteric heights.

Cheers.

P.S. Shoot me if i have ruffled any feathers!

arj

as i said earlier i dont dispute the need of isolaters or leveling devices for transports to aviod vibrations

its only that i feel that this resonant frequncy of the shelf/shelf materials ( after using an isolaters) having any audible effects ; is kind of pushing it.

however im a noob and ofcourse im looking for a more technical explantion for thesame

magma, my question was based on my experience. I am not a technical guy. My question was aimed to find a suitable neutral material for shelves or any tweak which can deaden the glass effect.

I rub snake oil daily on my amp after bath. Keeps it glowing and shiny new

try placing a playing card(or 2) between the amp and the glass. should work better than newspaper and should also be able to offer a more level surface.

another tweak may be placing a 6mm Acrylic sheet over your glass shelf and placing the amp on it.
if you like the result ( glue it on- glass and acrylic )

Another option is to use dynamat or Noisekill ( these are butyl based sheets 2-3 mm thick that are used in car audio for damping)
this should defineltely absorb all vibrations.
just dont peel off one side and use the sheet as is.
it will look better than newspaper almost like a thick silver sheet

yet another tweak
im my old office we used solid teak wood coasters( for chai!) . Something like this can be tried as well if you want to use wood as a material

The idea of vibration affecting jitter is overstated beyond a certain limit. What is jitter? It is, very simply put, the difference in digital data between what is written inside the media and what is read.

In most decent systems, this difference, if it happens, is miniscule - something like a couple of bits across a 10,000 or so bits or something like like .01 or .02 per cent. Now jitter can have two effects - one is where there is complete loss of data (seek jitter), and the other is mistiming (time jitter). Most systems have anti-jitter software. In the first case, they re-read the data a few times, and take the best sample. In the second case, they have a post read buffer where they recreate the signal completely removing the timing jitter.

i think you got me wrong..i was not saying vibrations cause jitter, but that the fact of jitter being important and hence its measurement came up later aftere lot of fights beteen subjectivits and objectivists

. usually PLLs are used to de-jitter as jitter is nothing but clock related and in a standard SPDIF it is quite easy to strip the clock and reclock using a better clock.
Reading a cd is a lot more complicated in redbook formats (yellowbook is a non issue) as a cd is not exactly written in bits but in words and with redundancy so need to use reed-solomon error correction algorithm to read it. problems in transport are not only from jitter but also from how well it can read the cd and extract all info...thats why some of the highend transports sound so very different in terms of resolution/details and microdynamics. and the importance of stability of the cd platter in isolation as well as materials to ensure vibrations are absorbed and not enhanced /transmitted.these cause not just timing errors but actual reading errors from the cd.

anyway the above is purely based in my experience with transports and PLL devices..i am really not a techie and more than happy to be corrected !

but i can understand where Myriad is coming from...materials do make a very difference in transports and speakers and any kind of material coupled to the above do have an impact theoretically as they add on.their own property as well.how much we can actually hear is dependent on the system resolution.

Hey Myriad,
You have asked a question from your experience.
Just ignore biased / irrelevant posts and go with some of the useful suggestions some have given you and post back your experience. They will gladly help you further.
Subjectivists/ Objectivists opinions are always there on all forums.
I Just now read a post by a fellow audiophile in Bangalore who just now upgraded to a VRDS transport by TEAC.
He and anyone who has heard the system say that it is the biggest upgrade he has ever done.
So much for zeros and ones !

Myriad, Please check the following pages:

Magic stuff: damping sheets
The TNT SandBlaster 1.0
The TNT Stoneblocks: graphite blocks clones

The stone blocks he talks about are known as Pumice Stones. These are very inexpensive trials, and can be thrown away if they don't work.

I deal in variety of Imported Snake Oil brands, my Tonga Rhonda brand is a hot seller, you can have a sample bottle for just Rs 1,00,000 (free shipping!) (buy three and get one free!!) .

One more tweak I would like to suggest is , put a big , 2 ft x 2 ft anti skid / VibraPod like mat between your Axx and sofa cushion , just feel the MAGIC!

I also observed that if you wear anything Green, Blue clothing , the Bass performance improves a lot, for Highs try Red, Orange , if you want mids to be better sounding , try burgundy, pistachio sheds.

One more observation, if you listen Jazz on Tuesdays , Fridays it sounds much much better than listening to the same track on any other days, for Pop and Rock it is either Monday or Wednesday only, Western classical sounds better only on Sundays.

I also observed that bathing using Mysore Sandal Soap improves soundstage while Dove soap improves image height. One of my audiophile reported that performance improves drastically all across the frequency range if you use Lomani deodorant (but make sure that you use only the original Made in France one)

One more very simple and cheap tweak is to put a coconut anywhere in your listening room, but see that the coconut always stands in vertical position without any support.

Hope this helps

Actually the best Isolation is actually pretty cheap..but messy. a sand Box ..sand does a really good job and absorption of vibration as well as isolation.

The solution shown in http://www.tnt-audio.com/clinica/sandblaster_e.html is a variation of using sand for isolation. He builds a box that is filled with sand, and places the unit of top of the box.

I have heard about this one. This can be done without mess. Get a metal or wood worker to make a 1.5 inch tall rectangular box roughly 2 inches wider than the cd player on each side. Give it a nice paint finish or polish. Fill it up with one inch of sand. Get a half inch thick polished wooden piece done. Dimensions slightly smaller than the metal box. Place this on sand and place the cd player on it. Works better than most isolation systems.

 

[arj]

yeah thats a good idea. the one i was thinking was placing cork coasters over the sand and under the feet but the fan if on can blow a lot of sand around !
Enclosing with a smaller wooden sheet is definitely less messier .

Has anybody tried putting a inflated Bicycle tire tube (rubber) inner under the CD player? One need to use a smaller diameter tube(used in kids bicycle).

Suhas, the problem with some posting from you is to decide whether you are serious or just pulling somebody's legs.

Mr. Viren, of Lyrita Audio, also uses this tweak (kid's bicycle tyre under the CDP). The tube is half or three quarters inflated.

And I came across one at the VDH site - it was a recommendation by Mr. VDH himself!!!


Suspend the preamp from the ceiling with elastic strings and attach a weight like a brick at the bottom!!!

what next? :lol:

No Venkatji, that Bicycle inner was a real one! By the way, by any chance did you attempt that Coconut trick(tweak) ?
