This is the Black Ravioli investigation thread, it may be fun...

How, in the name of God, how, could placing an amplifier on little rubber ravioli, (or whatever they're called) have any impact whatsoever on the sound coming out of the speakers it's driving?

Please note, this thread is designed to bring sanity and humour to the forum :)

Hmm, no idea, but a couple of options:

1. Perhaps some amps use smart phone technology? Attach tiny little accelerometers at strategically placed points within the amp's case, connected these to microphones, then add the output of the microphones to the signal into the preamp stage. Adding little rubber feet reduce vibration into these accelerometers by some minuscule, yet still audible (but of course unmeasurable) amount.

2. They don't

Can't really think of any other options, sorry :cry:

Since my name is guaranteed to have been mentioned in the sweepstake I'm not going to post in this thread...

Doh! :doh:

Well anyone who has a viewpoint is most welcome to share it, and I'd especially like plenty of input from those that can explain how the Ravioli works.

I'm not planning on buying any, just curious.

Microphonics ... look it up.

However I thought this mainly affected valve amps and the extent to which it affects solid state amps / cables I thought was negligible.

It doesn't, I just like to hear myself talk b*!!*x.

Why not try some?

.....na, scratch that......what a stupid idea, as there's no fun in that! ;)

Hi maxflinn

Best to stand on one's own feet.

All the best

Rick, that's so true in several ways :) :grin: :rofl:

I can see how they could be worthwhile on turntables and anything that uses valves but I'm sceptical about any improvements that they make with solid state amps and speakers (though I admit that I've never actually tried them myself).

Blind test anyone? :grin:

How do we know? It could be great fun :) , but there'll be no difference in sound, that's *logical.

*One buzz word to strike off the list.

Thanks, I'd missed some.

Q. Is it reasonable to assume that small vibrations could effect the performance of electronics?

A. Yes.

There's a reasonable and logical argument that they might make a difference.

Ravioli are very cheap so I'm going to put it to the test myself. My mate has a Marantz PM6003 amplifier with some B&W 685 speakers so I'll do some blind A/B testing using his system later this week.

How do we know?
Exactly, which was my point!
But a far more important point is that people will usually think they'll hear differences if they've changed something on their system, surely most agree on that? And in many cases there will be differences of varying degrees, Speakers all differ, amps, DACs and Source to a far less extent, and well, we know that when it comes to cables opinion is very much divided, though there's no proof they differ. But come on, Cno, Ravioli?? Surely the line must be drawn somewhere :)

But...I'd expect it to make no difference at all to a PM6003. A valve amp perhaps, where I could see how it might make a difference to the behaviour of vibration-sensitive tubes.
