The basic point that Dean and I are constantly making is that there isn't such a big difference between cheap hi-fi systems and audiophile systems as far as the properties of the transmitted signal is concerned. Oliver keeps talking about power filters, but were one to measure and compare the signals that are generated, there would be no difference. With different speaker cables there would be a slight difference, but it could be demonstrated beyond any reasonable doubt that those differences are well outside the audible frequency range. This does not translate to comparing a crappy car to a brand new Porsche.

I've had enough of you. 

I test things for a living. It's what I have done for the past 30 years. These tests involve extremes of temperature, pressure, vibration and humidity and I have an education and training that enables me to analyse data to isolate probable cause from actual effect. If there is an effect, then given enough data I will narrow down the possible causes of that to aid the designer to remove those causes to minimise the effects. These are not certitudes, these are possible causes. What you have described to me in every exchange we have experienced is perceived causes without observable effects - every single "improvement" you cite is a cure for a cause that has no discernible effect. Yes you can mechanically isolate speaker cables from external vibration, however, you have not demonstrated that this vibration actually causes an audio effect - you have waived your metaphoric arms around and touted some vague quantum physics notions of electron movement in a conductor and you have intimated that Faraday's Law of induction will generate a current in a conductor that is moved in the Earth's magnetic field - however I have explained that the degree of movement in the field-strength created by the earth's magnetic field is too small to measure - what I should have explained is that this induced current is magnitudes smaller than the Boltzmann noise created by the electrons moving in that wire through ambient heat alone - and if you wanted to eliminate that from your system then you really need to look at cryogenics.

 

So fine, carry on throwing dispersions all you like. I've stopped listening.

I don't think for a minute that you can tell a good speaker from a bad one (EDIT: by looking at the specifications). You can surely list some speakers that sound good, but I doubt that you could give reasons for why these speakers are good that would convince me. I still remember what you said a couple of months ago about subwoofers ...
