experiment with isolation??

Ptss .. once again a simple question has a complex answer that requires looking at the problem before applying a solution

How about that fiber that's supposed to block
hi frequencies. Any good? Best way to use?

...

There are many types of shielding tapes used for various purposes ... without knowing which one you are referring to I can’t comment or speculate on it’s effectiveness

Some of the problem stems from the audiophile’s perception of the word ... Noise... or maybe my it’s just my interpretation of it

I prefer the word ... Interference ... as it is two fold .. electrical and magnetic

I define “Noise” as the additional voltage that is added to the original signal and rides on top of it where it is carried forward to the next stage and it and the original signal are amplified and reproduced

The other side of the equation is the ... Magnetic interference that hardly anyone talks about ... it distorts the signal bending it out of shape

You need two different type of traps to capture each .. so addressing the “Noise Issue” in my mind only treats the noise riding on the original signal and does nothing for the Magnetic interference that distorts the signal reducing it’s efficiency

It takes 3 elements for Interference ... (electrical noise and magnetic distortion)... to propagate

You need a emitter or transmitter that sends or transmits the offending frequencies ... a conduit to carry the signal and interference ... and a receiver that will accept and reproduce this interference

If you eliminate any one of these 3 elements .. the problem goes away

Interference can be “Conducted” or that which is already coupled to the signal and riding on the conductor and ... “Coupled” .. or Airborne that which couples to the conductor which is behaving like an antenna and receiving the interference

Dissipating Airborne interference (noise and distortion) starts with blocking the emitters/transmitters ... digital chips spew RF in the Gigahertz range so you need a tape that will block and deflect at those frequencies

A word of caution .. when applying a tape to block the emitting chip it needs to be perforated so heat is allow to pass through and not build up in the chip ... trapped heat can over heat the chip causing it to fail

This only deals with the Noise/Electrical side of the interference issues ... transformers emit a stray magnetic field (Airborne) which can couple back into our components ... here RF blocking tape will not work as you need to use a Permeable material that will absorb the stray magnetic fields and dissipate them ... Magnetic interference must be absorbed and dissipated not blocked like RF ... most magnetic interference is in the 100Khz range I believe

I’m sure you’ve seen components with copper clad chassis .. the copper is a Permeable Material that absorbs the stray magnetic fields generated by the components transformer and dissipates them so that they can not couple back into the component ... I’m not sure about copper’s ability to block RF in the Ghz region but it definitely absorbs and dissipates the stray magnetic field from the transformer

Once you’ve blocked the interference caused by the emitter/transmitters .. you can “Shield” sensitive components from these interferences in the same manor ... for electrical noise a sheet of RF blocking aluminum can be position in top or cover of your components ... this will deflect or reflect away or block airborne electrical noise from entering your components and not allowing it to couple to your sensitive equipment and power supplies

To block the Magnetic Airborne interference (stray magnetic fields) you again need a permeable material that will absorb and dissipate the stray magnetic field ... stray magnetic fields can not be blocked and reflected ... they must be absorbed and dissipated ... so you need more than one type of trap to complete the job

I mentioned a third alternative in my original post ... the Audio Magic Next Gen Plus ( I use two of them ) when placed inside your component will act as a sponge absorbing both electrical and magnetic interference by transmitting a signal that is equal in frequency and amplitude but opposite in phase

As you can see it’s a complex series of issues that needs to be looked at from many different angles and treated in various way

Sorry I can’t help you with the Fabric your looking at ... my best advice is ...

Fix what you can and manage the rest

Davehrab, thanks for the detailed insight. It has given me hope for improvement in more than just my digital components.
I am curious to learn how the "Audio Magic Next Gen Plus" detects the precise "frequency and amplitude" of the generated noise while simultaneously generating a precise inverse to null noise. I don't need "trade secret" info- however a device of this value (and I see its benefits in countless applications) but I would expect this "device/process" to be protected by patent. Can you advise the patent number?

I am curious to learn how the "Audio Magic Next Gen Plus" detects the precise "frequency and amplitude

Ptss ... I doubt it detects or senses the Interference and then implements an opposite and equal signal

I’m sure Jerry has measured the emissions and knows exactly what the offending frequencies are and how strong their amplitude is
'

My guess is to cover the Magnetic interference (power transformer) as well as the Electrical interference (clocks dacs diodes) he needs to generate a signal from 100Mhz to up in the Ghz region to cover everything ... also knowing the interference's relative strength/amplitude ... he can custom tailor the output of the signal and just create it 180 degrees out of phase

Not sure on the Patent .. just may be his intellectual property as it’s his design

I think this device is most effective inside a digital component like a CD player, Dacs, Computer server, Cable TV box where a great deal of interference is created

The main purpose appears to be soaking up the interference generated by the digital component before it can recouple back in to the same component ...

Analog devices like preamps, tuners, class A and A/B amps do not have chips and clocks so they generate less hi frequency interference ... here the Gen Plus will be less effective .. although everything in it has a transformer so there are Magnetic fields

Hopefully you now see that there is more than one perpetrator ... the Noise of the electrical interference and the Distortion of the Magnetic fields ... so you need more than one solution
