RE: Black Ravioli

All my gear is on glass so i found adding the black ravioli made a huge difference to the sound, unfortunatly weighing up the cost of it compared to other isolation products i could'nt part with that kind of cash, i have 4 semi firm black sorbothane strips under my stuff which cost me nothing and i get very good results from that.. the brightness was eliminated instantly, soundstage also improved..

RE: Black Ravioli

 

Reminds me of the 'Flux Dumper' idea . . . was it 'HiFi News & RR' that put these out in the 80's, two heavy blocks, one placed on top of each speaker. Certainly changed the sound, better or worse??

Reading the web page blurb for BR . . . its very vague? . . . as 'black arts' often are . . . been there, done that Dirol

I'm certainly not putting them down, but a few bean bag/rice bag (fine pulses) type weights, strategically placed, may??? have an effect?

I'm looking at Sorbathane myself at the moment, relatively cheap, see what happens?

I feel the cost of some items in the hifi business are more along the lines of; 'think of a number, double it, ad the date, see what you have and will the market stand it'? . . .

Today, it was announced we are heading into a second dip recession, amid apologies and dismay . . . the word 'sham' comes to mind? There is going to be even less money about. The throw the numbers in the air strategy will not work, tighten your belts . . .

I think a little bit of DIY, or at least 'options' thought might be a good idea . . . ?

The prices are here (scroll to the bottom of the page):

I found them much better than Sorbethane, all be it at a cost.

Thanks a lot! So the single pads are 25GBP...I guess you need 3 for the amp...where else did you put them Cno? Btw do you have a pic of your system (very curios)? Smile

...now look what Mr. Law has started!.....at some point, I'm going to figure out how to do it and give it a try. If I manage to sort some photos of my Auralex Gramma solution, I might get round to my kit.

The only place I have the BR is under the DS.....it gets quite expensive.

Tube amps can suffer from "microphonics", this is when the mechanical vibration of the tube can cause the internal components to vibrate, which in turn effects the signal  ie.the tube is acting like a bad microphone....BR is supposed to be particularly good at helping this.

Waiting for your post as well as I do think vibrations reduction has to be taken into account in any decent hi-fi system

seems a shame that the hi-fi manufacturers don't consider that, what a missed opportunity...

i think the shop selling this product should be done under the trade descriptions act for describing that .pdf as a technical paper!  what a joke.  the only info they give is that a material used in kitchen worktops, corian, is in them.  i'm glad i read it though, the part about using them under a laptop was hysterical.  i can see how this product could de-couple kit from outside vibration being transmitted through the support, but how it could do the same for psu vibration is beyond me; the vibration has to pass through the circuitry and case to reach the foo!  my main thought though, is whatever happened to just listening to music? :doh:

Interesting to read that even the black ravioli requires a burn in period...

RE: Black Ravioli

oh bay the way the reason I was given for the amazing affect was that the br changed the vibration from the sound waves into heat which then dissepates taking away any undue effects that the vibrations would have on the sound

Thank you Sir, for confirming I'm not completely nuts (or there are at least two of us). Smile

Nha, I also think they might help a lot. I read an interesting forum (in Italian) of a guy who tried to make something quite similar to the BR and posted the final product on the forum itself with explanations on how to build it. Well, everybody who tried it admitted they helped...from quite a lot to amaing results...

Will try myself when all the rest of equipment will be in place Smile
