Foil damping tape as a tonearm tube wrap?

Dear @celander :  """  certainly be a step in the right direction in terms of resonance control, stiffness and strength.   """

that'as the main concept of the wrapp subject. Took those inside listening cartridge  frequency range out of the cartridge signal and that's why the 3M 434 could works with no problem at any temperature but you can go to use the wrapping with other kind of item. Some one mentioned teflon tape that seems to me a little " soft  " for this job but you can try too.

@celander : At the end what we want is to tigth ( tension hold to the arm pipe ). with enough force the arm pipe and if the foil/wrapp has damping characteristics the better but not essential for the job. I think that even at 30-35° it works. We need the damping all over the frequency range not only in one frequency range, we need at least at both frequency extremes as a fact the bass range is so importamnt about.

The Sumiko works because it puts enough force against the arm pipe " killing " vibrations/resonances where it makes its harm " work ".

@johnnyb53 , with this damping method you can't overdamp the tonearm because you are not altering the pivot bearing free movements but helping about.

@celander : That’s for optimal results on airplanes and the like. It will works at 20° to 25° with no trouble in wht we wnt to works.

I ordered, is up to you.

Dear @celander : Just do it with the 3M 434. You cn't go wrong.

Dear @lewm  @celander : A tonearm muyst be an inert device but no single tonearm out there is inert. Designers try to design tonearms well damped many with out success and other choosed for no damping at all, these ones are the worst no matter what.

What is happening with OP cartridge is not only for the Decca London but any cartridge signal will receives dramatic benefits that only a deaf man can't listen.

When Sumiko puts in the market an arm pipe device was because they made it several tests but my first hand experiences with over 15+ tonearms and dozens of cartridges told me and tells me that Sumiko was rigth.

Lewm, you always think on theories or just imagination on subjects as this one. Do it a personal self favor and test it and you will see that always makes a difference for the better. Test with the 3M 434 that will mantain almost the same inertia moment/EM.

@celander , the headshell you bougth is not well damped and that's a problem not only for your cartridge but for any one.
The arm pipe of your tonearm is made for a well self damped magnesium material, try with these magnesium ( that match the toneam magnesium material. ) very well damped headshells and you will confirm what I said about:
