    Just buy a piece of MDF and a 16" inner tube. Paint the MDF to taste, inflate the inner tube a small amount and place the MDF on top of the tube on a flat surface. Hey presto, it almost does what a seismic sink does. Certainly it performs very well, and for the money is extremely good indeed.

    im half way there anyways.ive got the mdf. if you dont like painting then rub the mdf smooth with sand paper or wire wool and then rub some white spirit on with a cloth. it gives it a dark wood effect and is quite pleasing to look at. dosent fade either.

    Door stops and balls

    You can make cheap supports that work very well by taking door stoppers and putting kids' superballs or squash balls in them. Then just place the equipment on top.

    The squash balls act as an easy-to-use air support. They give most of the benefits of an inner tube system but are much easier to set up and level.

    Superballs are interesting and highly effective. I use the door-stop/superball supports under the existing legs of some equipment, under the chassis of other equipment. I'm told that they work by transmitting vibration from the vertical plane to the horizontal.

    Don't underestimate the effectiveness of door-stoppers when used in combination with these balls. These combos can be more effective than many professional decoupling supports sold with fancy packaging at many times the price.

    The only downside being that your kit bounces across the room now and then.

    True. I used to use Flubber but that was even worse. My original Planet is now lost in space - probably how it got its name. :) Steve

    I've seen similar sugestions, but i've built the ball bearing and spoon to good effect.

    another suggestion try the hard wood door handles from wilco, they work like RA's oak cones but at 100th of the cost.

    Dried up silicon works like sorbothanne too or some reflexology squeeze balls. Take the stress out of your kits:)

    yeah, I've got some inner tubes under my amp and cd player...it works fine, tho, a bit boomy at higher volumes, but works well for a cheap upgrade!

    or the (in)famous vuk ball nutter. a nut with a ballbearing on top as similar to that used on the naim fraim.

    how about some up facing spikes with glass or mdf on top (i believe the patent has expired on a certain implimentation of this if not then please excuse me).

    cheers

    Very true! But it only happens when you hit the component with a squash racket.

    Cheap Isolation

    Had a few evenings playing around, i tired many permitations but this set up worked the best.


    From the top downwards.

    CD Player
    Inner Tube - lightly inflated.
    MDF - 20mm thick
    3 Wooden Door Nobs. 6 for tenna. (after reading about RA Cones)
    Very heavy pine table. (had for a few years already)

    The same was done with the amp.

    Again, top downwards.

    Speakers
    Blue Tak
    Stands
    Spikes
    Rounds feet thingies that takes sprikes
    MDF - 20 mm thick
    Blue Tak
    Floor.


    And how does it sound, much much better. Could not pull myself away from my favourite tracks for 3 hours on Monday night.

    It's good to see that B and Q now stock HIFI accesories.
