Seriously though, everyone should be very skeptical about these claims
for CF. If you want to shield a component from ambient RFI, you want
to make a Faraday cage out of the best conductor you can find - NOT
something resistive. I don't know how good a conductor CF is for RFs,

The big problem with ignorance is that it limits your ability to sort
out what you know and what you don't. Those who don't know about a

wrap your stuff up and expect to hear a difference, therefore you hear

The thread has gotten off the point of my post: RF is distorting the
sound of the SB3.
How can any sort of comparison or recommendation be made when something
so prevalent as RF effects the sound?
Perhaps my SB3 with shielding sounds as good as a Transporter?

As far as I can ascertain, the EMI shielding capabilities of Carbon
Fibre are similar to those of aluminium foil. It's principle benefit is
that it is non-metallic which makes it ideal for certain critical
applications (eg avionics).
I'd go with the tin foil, but you might find it has more effect wrapped
round your head. Gotta be worth a try!

Phil the tin foil will reflect the waves created by the sb. So the tin

I believe that the hazards of carbon fibres have been greatly

very different from those of gross carbon; yet the hazard analysis
seems to have been carried out as if it has the same properties. You
can't have it both ways. Some
