Well the use of rubber compounds as isolations isn't new. From halved squash balls to tailored sorbothane pads (the same stuff as squash balls) it's quite a common solution to vibrations or, more accurately, energy absorption. Over to our scientific corresspondants....

I can see how it could be effective under a CDP or turntable alright but I've no idea how it can make an audiable difference under an amp. Anyway I'll have to try them out.

Oh I agree... it's the
black arts.

Four Black Ravioli arrived in post today and I put them under the amp after removing the rubber feet. Previously the amp was resting on squash balls. Clear improvement in the sound, greater clarity across the spectrum and improved bass. I have only listened briefly but the sound is good. If there's anyone flogging them at the show this weekend , snap'em up.
I got mine from
http://www.signalshifi.co.uk/manufactur ... oli,i.html 20 pounds each and free shipping. (They are also on the Kronos site but it doesn't allow for shipping to RoI addresses (David C , if you are reading this you might get the website adjusted )).

Thank God. It's not just me.

Well, have you not opened one of them up yet?

I haven't. I reliably informed it's not worth it. If you try and cut them they heal as fast as you run the knife along them. You need a laser apparently.
They don't like being moved about much either. As they're made up of layers I suppose they all bed-in once there's weight on them. Once repositioned they take a day or so to settle in again.

The Black Ravioli pad is constructed of a number of layers of two differing materials that are held within a fabric enclosure.One material layer is a proprietary laminate that provides the means of a very efficient and fast energy conversion and the other layer provides segregation that contributes to the coupling/de-coupling scenario.The pad is intentionally pliable to allow good coupling with the equipment. This feature also allows the equipment to settle and find a relaxed position. The effect of the pads on the system should become apparent almost immediately but due to the settling process full performance may take a number of days to achieve.
The layered structure of the Black Ravioli pads is designed to give a amount of de-coupling but the design does assume that the pads will be used on an appropriate non-resonant platform that is sited on a stable floor, or wall. The spacer and risers are specifically engineered from corian material to provide further decoupling as well as providing additional clearance to remove the existing equipment feet from the solution.
