Not sure I have the equipment to measure it properly. I know that, on a dry day, I can pour a kettle of water onto the head of the spike and it helps the SQ. What mains lead do you use for the kettle ?  |

A kettle lead, boom boom!

After some struggle, I have the P10 regenerator on four Black Ravioli, matching the others under key components in the system. This wasn't easy due to its 33kg and the difficultly of moving the bugger with the tips of my fingers. It's not quite level on four feet, rocking slightly. However, I am assured that the BRs will settle and the P10's weight and will end up sitting evenly on all four. This is key to how they work, requiring contact with the flat underside of the component. Update: the P10 never quite settled evenly on the four BRs, so I cheated and put a £2 coin under the foot in question. Now the P10 doesn't rock at all, but it really rocks!! Sound quality improvement is in keeping with the other components using BR feet, these marvellous blocks really getting the most out of the regenerator. |

I thought you might find that my memories that both my Balanced mains and P500 responded well when I used the feet of silence with them

Good news. Wonder if we need to bring coins into our testing regime |

Hmm. *Black* ravioli must sound good, but surely degradation from a gold coloured coin - or is it totally hidden ?
Need to think about non black kit not on view.
Does it mess with the hifi time continuum and other black activities .......

For the money they cost, what exactly is inside a BR thingy? You could cut your own foam squares and maybe laminate them somehow. Total cost each wouldn't be much more than 2p each, surely  |

Black magic, Kevlar and other stuff in the multiple layered Mk 3 jobbies - from what I hear

Ever tried bubble wrap ?
Big or small bubbles, could make the difference.
Cheap to try.

I've tried all sorts, not yet Bubble wrap !
If I have this right there are 3 areas to cover
Stopping vibration from the kit itself
Stopping vibration getting into the kit, from external or feedback
Electrical rubbish getting into the signal - which, so far as I know only Black Ravioli supports improves
and I bet there's another one or two

I've tried lots and lots of equipment supports, even my computer speakers are on cones and feet that are spare. Springs, inner tubes, bubble wrap, opposing magnets, the lot. Nothing comes close to Black Ravioli, the construction of which is apparently complex. They don't just do isolation, they do damping and coupling.

I've just added four more mains noise suppressors to my collection (distributed around the house's ring main):
- Kemp Elektroniks SNS-PLUG
- No Noise Ultra SE
- Tacima SC5723 x 2
I'm aiming to have the 'quietest' mains in the country. The cumulative effect of distributed different models of suppressor is amazing!

I can see logic in having different makes if they are only 100% passive
Can also see logic in just one make
How many do you have in total ?
Are they beside specific kit, like fridge, heating controller ?
At measured points in the house ?

They are all passive and each have different filters and absorption frequencies.
All downstairs on the same ring as the system, spread around the rooms. Not particularly associated with a device. The combined effect of 10 of them (at the last count) and the PC being on a through-filter acts to impressively reduce the already low noise floor and bring out more detail.
During experimentation, I found out just how much noise still gets through the regenerator, so this is the other half of the noise reduction solution. The sum effect is pretty large.

My system is almost alone on its own ring
I think only the TV and Tivo on that ring.
TV off for serious listening
May have a couple of lights on that ring too.
Wonder how much benefit they would be for me

They would have an effect as long as you have noise coming in (or internally generated). To an undefined extent, then, anywhere. The ring reference is only to localised the suppression, not to suggested that they only work that way.

No easy answers then
Testing required
