I think I have an idea of what is going on now !

I was just browsing Martin's blog and came across the link to this.
Interesting points being made and all quite probable to my mind.
Still, I would guess that simple noise from the same outside sources rather than vibration would explain systems sounding better at night and having a much greater magnitude of effect than vibration effecting the equipment. The noise floor of the environment decreases so much at night and details appear which are simply masked by traffic or people's activities. I experience the same also when listening to well sealed in ear headphones in a quiet room. Once you've got a lower noise floor, you can turn the volume down (saving your hearing with headphones) and so the room intereacts less, equipment is less stressed, lower noise produced by the equipment etc etc. I guess the only way to test would be to live in an isolated place where human or natural activity (bird noise etc) doesn't occur, like in a desert or up a mountain.
I'd love to listen to a great set-up in a purpose-built, sound isolated music room.

There is so much to this subject, I think it (and mains power quality) are at the root of extracting more from an already good system. I'm learning all the time about which coupling/decoupling methods work best with which components.

Today Christmas Day there is the least vibration happening in the UK.
No public transport or aircraft
Minimal heavy vehicles
Minimal number of cars moving around
Most people indoors
No commerce trading
Minimal pollution on the mains
The chance to hear your system at it's best. I enjoyed my vinyl this AM but was it for the reason spoken about?
I went outside to check it out. It was raining, splish splash, someone set off a firework bang and a vehicle passed on a nearby main road.
Anyone else check the idea out? Or will you accept it as plausible to you?

Hmm.
Funny I just took our Lucy (JR and runaway dog) around the garden on the lead and noted not one single aircraft in the sky.
Round here that is a big , no massive change. I can usually pick up at least 3 in sight at any one time. Tried to count a lot one day but kept losing the count as they moved around, 10-12 maybe in eyesight.
Dead quiet all round as you say

I find it hard to differentiate between the effects of system feedback and any possible effects of external vibrations EXCEPT that I still hear the benefits of footers like RDC Cones even at low volumes.

I am pretty much with Martin on this howerever I will add that some equipment seem to benefit more than others

I woner how different the SQ is for those folks living on remote Scotish islands with little of the things that are aplenty in mainland life/environment compares. The lecure suggests there might be a very noticable difference.
Any members from such remote locations or know someone who is able to comment?

Townsend Audio give a fascinating lecture on how vibrations affect your hi-fi system.
My main problem with this, being such a sceptic, is whether they have indeed done serious and scientific research, then made a product that will solve the 'problem' or whether they're just using theories to sell a (rather expensive) product. Amongst the other problems I have with this approach is that when the speaker makers test and tune their products they presumably don't use isolating feet, stands or whatever, so if you start using them on your speakers you're not hearing what the manufacturer wanted you to hear, and it's a bit hit or miss whether that makes them better or worse. |

Not injecting extra garbage into your precious signal can only ever be better.

Who knows if their rubbish matches ours Some of the studios use Mana, (Pink Floyd I think) They may use other items too |

Max Townshend has regularly produced results I've liked and so this interests me. The only thing is, his products have a price tag that I just can't justify. I'm thinking more in terms of a DIY attempt to achieve similar results. Surely some automotive equivalent can be identified and adapted. I'll do some digging but I really fancy trying bouncy feet on my Minstrels. I might even try making some feet from anti vibration mounts. They have worked well in Roksan decks. At least they are cheap to play with. Anyone tried any unusual approaches as an alternative to spikes?

In the past I used computer mats between standmounts speakers and the stands, did help and was a cheap solution to add further isolation at the time.

An interesting RDC product is the one with spikes ! Their site has just changed, but take a look at RDC-MLB + RDC-MLS and others on clearlight-audio.de/German speakers welcome (Willkommen !) |

RDC Cones replacing spikes worked wonders on my system rack.

My kit (Squeezebox Touch and Paul Hynes Power Supply, modded Jolida Dac and Conrad Johnson CA200 amp) are on top of a big brick fireplace (6' high, 9' wide and 2-3' deep) with the Amphion Xenon II speakers on the floor either side of the fireplace.
Any idea what sort of supports/cones/spikes etc are likely to work best in this situation? There's no rack at all - all bits of kit are currently just on their normal rubber feet on top of the fireplace.
I guess I need to couple the kit as well as possible to the massive fireplace. It has been suggested that a mixture of coupling and isolation on each bit of kit is the way to go. Any thoughts?
Cheers. Bill

You cannot go wrong with RDC cones, unless you have very deep pockets you wish to plumb then Stillpoints
Start with just the cones. 3 each is fine unless you have a reason to go to 4. Wobbly kit or a safety aspect
Add single then double RDC bases if you want.
Stick some sort of rack underneath that. My preference is a Mana Reference top, table or rack.
Have a look at Martin's blog and you an see even more to add in

I'm thinking that I should use the fireplace as a 'sink' for any vibrations (it's solid), so not sure why I'd want to add a rack. Will the RDC cones couple or decouple the kit from the fireplace?
Thanks. Cheers. Bill
