Vibratory or Not?

This is a discussion that for me began on the Stereophile forum which went horribly wrong in my opinion. I was wondering though if this same topic could be discussed here as it comes up a lot in one form or another. My background has been about vibratory tuning as far back as the 70's work in the recording industry and continued into home audio and beyond. The audio signal is one that can be easily tuned, I doubt there is much room there for debate, but we will see, it's Audiogon after all. This being the case I have always concluded that the audio signal is vibratory so has anyone I have ever worked with. It's a common and sometimes even daily practice for someone here to make a vibratory adjustment changing the sound which is obvious to all.

On some of these forum threads however you will see posts saying to get rid of the vibration, without any explanation as to how to remove vibration without altering the audio signal. Every vibratory move I have ever seen done changes the performance of the sound. I've also been a part of the variables of the audio signal during play in real time. If the audio signal is not vibratory how does it change?

I invite you to discuss the vibratory structure and nature of the audio signal.

thanks, lets keep trolling to a minimum please

Most audiophiles have a thermostat. Besides, unless there are very big swings in temperature it’s not really an issue. The same applies to the speed of sound in air. Maybe Superman would worry about it in his Fortress of Solitude. But not the average audio dude. Not an issue audiophiles should worry about. If that’s your best argument against isolation it’s not very convincing. It doesn’t make sense and if it doesn’t make sense it’s not true. You cannot fool a thermodynamicist!

Hi Geoff

Where are you placing your springs? I have always found them to be very sensitive and very equipment dependent (one size or type does not fit all). I've also found them to be material dependent depending on the types of materials being used in the components themselves.

Also with the air tubes you didn't mention that the component needs to be properly weight distributed. The bladder products perform very inconsistent because of the distribution of weight most heavier components have.

When you do your testing do you use more than one bladder. Reason I ask is because using one bladder doesn't seem to work very well because there is less pressure being applied to one area of the skin than another. One part of the bladder may have 8 pounds sitting on it and another may only have a few ounces.

I hear tell the ancient Romans used a pig bladder for their turntables.

Michael, let me draw your attention to my posts earlier today in response to the same and related questions.

Geoff in regards to isolation you don't believe in the audio signal being vibratory I take it? How do you describe the variable interaction the signal has with the fields, or as some would say field?

In our stage testing we have been able to establish such control as to virtually be able to shape the soundstage by using the audio signal's variables without distortions. With isolation as you term it how are you able to make compensations to the sound. I have never heard any two "isolated" systems to produce the same sound. If a system is isolated you would have the same sound would you not with any other "isolated" system, which has never happened to the best of my knowledge.

interesting conversation
