RE: Isolatton Products - what exists?

No matter how strong the scientific argument and consensus among scientists there will always be people who reject the evidence. It happens on so many scientific topics, from climate change and vaccination to nuclear power and renewable energy. You only have to look at some of the comment threads on online articles: where scientists might agree with one position, it seems the majority of comment will stridently beg to differ. Well-established science is taken by many as just one of a range of possible viewpoints, no matter how credible – or incredible – those other viewpoints may be.

This foo thing is harmless really when compared to some of the other irrational beliefs that some people have. It's interesting though why some folk are more susceptible than others.

PS If the building I was in was getting that sort of seismic twisting I'd be concerned about much more than my hifi.

PS I had to Google "hard knee house curve".  Wonderful stuff.

No Nonsense here - http://en.wikipedia.org/wiki/Equal-loudness_contour

Hard knee house curve is based on solid facts - humans dont hear bass in a linear fashion, all say they want a flat freq reponse but the reality is the deeper the bass the more volume is needed for it be audible at the same volume.  A flat freq response is not actually flat in how you hear it.

Therefore a curved bass setup actually works better - and followinng the advice you set it up to your ears

The hard knee house curve addresses the issue of bloated bass caused by a standard house curve - once you have your system setup like this I doubt you could ever go back as you could hear where the bass is severly lacking.

OK, now I'm more calibrated to your requirements, I'd recommend you try these:

Car tyre inner tube

Car tyre inner tubes under whatever boards are supporting your equipment, inflated to about the right pressure. You can buy them for £7. I've seen and heard this approach used with a £12,000 vinyl source.

 

Sometimes commonly available alternatives are at least as good as more expensive dedicated items.

The weirdest thing is he doesn't seem to have anything that needs to be acoustically isolated at all. :? .

RE: Isolatton Products - what exists?

People dont read before writing - I am guilty of this as well but I have covered this several times

Read Bad Vibes in Stereophile - all products need isolating from themselves and other products.

 

Here we go again with the counter argument.....

I will defend the right to...

TrevC, I have my solid state amps plonked on the floor and my CD players plonked on whatever surface or stand is convenient for putting the disks in and out. It all sounds fine. But there's really no harm in the original poster trying a few isolation possibilities to see what difference they make in his system, especially if they're relatively inexpensive, or he can sell them on or return them for about the same price he bought them for.

I did and no they don't.  It's also worth noting that the article was written in 1995, way before computers were being used as playback devices and mp3 players were available (ie no moving parts playback systems), so to try and apply it to modern tech is folly.

 

Plus the article dares to say talk about studios when it's obvious the writer is just a hifi nut and doesn't have a clue about what goes on in a studio.  Does he not think that after all these years, those professionals who create the music that he so badly wants to listen to in "high fidelity" wouldn't have tried such things and come to their own conclusions.  Quite frankly the whole article smacks of sanctamonious bullcrap of the highest order with somebody who is sooooo obsessed with tweaking that they've lost sight of the plot.

Bloody snake oil brigade

 

Lindsay T - just because you put your kit on the floor doesnt make it right - thats the worst place for it to be just to point out, even on a concrete floor although I am guessing yuo dont have an exposed concerete floor

 

I have done controlled blind testing based on isolation and that proved to me there and then and several others that it is important and does make a  difference.  In fact I didnt know isolation was being changed so there was no bias at all.

Secondly I have tested this myself and heard it with my own ears that isolating certain products improves sound quality.  In my room there is a lot of bass - I like it this way - and it sound best for it - its necessary to have a lot of bass to support a full range sound.

There is energy moving into all my compnents I dare say - some more than others.  Now this definately harmfil of delicate imaging cues for one and I have heard it with ym own ears make a significant difference to the transparency of bass I get from my sub.

There is no snake oil here a piece of polystyrene under the power supply feeding my audio pc.  It makes a difference simple as that.

 

I have looked at the many different products been linked too - some are very very expensive, overly expensive but not all are.

Thanks for the input
