    What's the crack with squash balls for isolation? Are they really any better than standing the units on top of each other??

    I know a dedicated rack will be better, but its all down to funds (or the lack of them!) :D

    Cutting squash balls in half and placing them underneath equiptment absorbs unwanted vabrations and has long been a cost effective solution and will isolate your equiptment far more than stacking them on top of each other. Same reasons speakers and speaker stands have spikes to isolate them.

    As an example of how well it works I used some between my centre speaker and tv before the speaker moved to its own shelf. Before using them the picture on my tv would flicker at loud volumes (actually took me a while to figure out it was the centre speaker causing it), a couple of squash balls cured it completely, I was well chuffed!!

    Cheers Gary.


    Just what I was looking for! :thumbsup: £1.99 for 12! Bargain.

    Im confused about the curtain rings & castor cups :confused: Did you cut the balls in half??

    Thanks again. :clap:

    Aside from any "isolation" or "coupling" benefits (they do one or the other, I've yet to decide which!) they do provide the benefit of adding some breathing room around stacked components.

    I'm expecting an Isocushion to arrive next next week so I might be able to delve into this a bit more then :)

    No, I'm relying on the compression of the air in the ball for isolation rather than the rubber.

    An interesting thing that was shared to me by a CD player designer, which I'll attempt to shorten a bit. The mechanism to swing the pickup head around is apparently by far the biggest transient consumer of power in a CD player. The power in low-cost CD players is usually shared between the audio and the motor circuits and this creates feedback or spikes in the supply and affects the sound. This applies to the player having to recover from movement which shifts the pickup head around, which can apparently happen with even minute shocks. Fortunately, the full effects of this may not be picked up by low-cost amplification ;) The cleanest performance is therefore enjoyed when you have nothing other than the movement that's absolutely necessary being applied to the pickup head.


    There you have it. Any sort of isolation does seem to make sense from this viewpoint, but the better application-specific products would seem to make more sense. Foculpods are good and are at the lower end of the isolation cost scale. They're also a godsend with external hard disks :D

    Why would a hard disk be suseptible to vibration? If vibration caused "errors" on hard drives, then it would corrupt data, pure and simple. Hard drives need isolation far less than CD ever will, period.

    I can see the sense in isolating a cd player or HDD recorder or other marginally sensitive piece of equipment. But, if the designers have done there job, you shouldn't have to.
    Sure enough Hard disks are susceptable to 'impact' shocks but most modern HDD have anti shock protection built into the design. Same goes for any half decent CD Player.
    The squash balls are a good idea but I'm not sure they're really needed unless you have a turntable.

    Chi-ching exactly PB.

    Also does the vibration from a spiining disc mechanism not cause more internal vibrations that anyhting that goes through the feet of a component ?.

    Sometime some daft claims are made on hifi forums for some reason, can you imagine isolation supports being quoted as a solution when needing to get data transfer from CD-Rom to HD for example? For some reason when it comes to hifi all logic goes out the window – I know not why but if a CD is vibrating so badly that the erorr detection kicks and fails missing data, you will know about it. Where does this stop for example there are those who believe the IC connections into the CD player or amp, actullay impart microphonic vibration as well.

    thats why you can get seperate transports and DAC's.

    No, what I mean is that they go "rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr" on my desk. Foculpods later, blissful silence.

    The cost of the squash balls is nothing compared to what it's going to cost you to duplicate your kit so that you can DBT/ABX the squash balls before posting your comments. :D

    DBT
    Double Blind Test

    ABX
    An ABX test, that is, you listen with, then without (knowing what's being played). Then someone changes whatever the test thing is and you decide which is best. The catch being that for the X test it's done secretly so you've no idea if you're listening to A or B.

    The thought of warming up squash ball halves before listening is a worrying one, somebody's bound to find a "difference" :laugh:

    Admittedly I won my Isocushion www.isocushion.com but even if it doesn't make any sonic difference beneath my DVD player (I predict zero change) it will at least look very nice. :)

    I put squash balls under my home cinema amp (crappy Yamaha HTR5630) and it actually did make a positive difference to music (using the DAC in the amp). For decent equipment it probably wouldn't make that much of a difference though.

    All electronic equipment suffers from microphony (to a greater or lesser extent, dependent on the use of, and type of capacitors/inductors used), whether this is audible or not depends on the resolution/transparency of the equipment.

    Just make sure you warm them up before you use them and be careful of the compressed gas that will ooze out. :laugh:

    If half squash balls are so good surely someone is making chlorine-free linear allophanate low modulus polyurethane acoustic decoupling hemispheres at £89 + VAT for 4?
    (Or am I just a cynic?)

    For what its worth, I had some good experience with using 4 x 1/2 tennis balls under my speakers. This was a tip I got from a friend in a hi-fi shop when I was asking about getting some expensive speaker stands.

    I was skeptical at first, but tried it and it make an appreciable difference to the bass response - really seemed to tighten it up.

    Nice thing was that it cost me nothing (I had old tennis balls at home anyway) and was really easy to do an A-B test - just lift speaker onto and off the half balls and hear the difference.

    Try it... a lot cheaper than speaker stands and doesn't harm the floor like spikes.
