Surprised by the amount of vibration when I touched a speaker stand last night
Caravan - For Girls who grow plump in the night - at some volume
The Isobarik itself had some vibration
Isobarik stand had a lot more, that is spiked into a
Mana MDF soundbase and that was vibrating around the same/slightly less
Mana sound base under was vibrating around the same/slightly less on the front, left to right but nowhere near as much on the side, front to back
Assume I want this vibration to be at least minimised and now thinking about the next move......
More soundbases should help

I am at a loss to understand the logic or the physics or multiple soundbases . Surely , rigidity decreases with every successive base . I do however understand the economic arguement  |

Not quite sure what vibrations you are worrying about. Its in the nature of speakers that they generate vibrations - its how they produce sound. What you don't want are speaker cabinets and stands chiming in with their own sounds due to a resonant frequency in the audio band. Having just taken the stands off my ESL63's to access the gubbins inside and repair them, I am aware that it is steel box section, with a distinctive chime. Options might be to sand fill to deaden that sound, but probably sticking a bit of felt on will do just as well. No amount of spikes or funny feet is going to fundamentally change the issue of the stand itself resonating. Indeed, thinking as I type, given that I am looking to damp the steel stands, the fact they are resting on carpet, and not spiked, is a positive asset. The main issue with them not being spiked, is that, theoretically, they move and "blur" the sound, but I'm not sure. There are holes for fitting spikes in the base of the stands, so I daresay at some time in the quiet season I'll try it, but to make the A:B fair, I would then need to damp the stands with a carpet replacement (an old blanket as a temporary measure) I don't suppose that ramble helped much, but I feel better for it  |

More soundbases should help None at all should help a lot more. Sound improved with one under each There is a guy in Germany with 10 each  |

Not worried about the vibration, just wondering if the sound will improve if it goes away
Wanted to try the Stillpoints Components stands but they are too small to fit under the Iso stands with included crossovers
Other ideas also worth exploring of course
Another idea : if the speakers push the vibration into the bases, then the speakers vibrate less, so maybe a good thing

My Royd Sorcerers have virtually nil vibration, which am sure is down to them being 7L sized (Linn Kan / LS3/5a style), but weigh 11KG each! However, I can feel vibrations running through the speaker stands, I think this is a good thing as they are doing their job & sinking energy away from the speakers.

This vibration thing seems such a big area
I'm glad to say so far I'm improving the sound spending not too much

On vibrations I do think that, in general, sinking vibrations via lighter stands is better than mass loading stands to damp vibrations. With the exception of some speakers I haven't heard them but many report ProAc standmounts like the Partingtons etc.

Mana is a bit of both heavy and coupled. Sometimes a component isn't suited to a Mana shelf as it is highly coupled to vibrations including airborne (although it also 'sinks' such vibrations), which is why my DAC's stainless steel footers are now on Black Ravioli pads.

I find everything I have tried so far makes the Mana sound better, in order of improvment and ascending price
Wooden cones
Pods
RDC cones
Black Ravioli
Stillpoints

Isolation & Vibration needs to me drained out of the speakers My speakers float on ball bearings & wobble So, if they wobble, they probably move in accordance with the cone excursion of the drive units when music is played. Surely that is not conducive to good sound reproduction? |

You would think so Greg but I have been standing speakers on three billiard balls for a few years. They sound considerably better than spikes to me.
Quite possibly at deep bass there is a loss. But gains overall so much I wouldn't go back.
When I had some boockshelf speakers in my office I put them on marbles and spoons and they sounded a lot better with that degree of isolation.
It shouldn't work but as you know I only let my ears guide me.

Billiard balls - that's a new one! How to you prevent lateral movement?

You don't - you go with the Rawhide approach.
Roll-em, roll-em, roll-em, RAWHIDE!

When I fitted a hard floor in a flat I rent out I did it all in engineered floor. Not much more cost than glazed mdf and last my lifetime.
But I don't have to have good sounding music in a flat I don't live in.
