TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ?
I had a Rabco in which I replaced the arm with carbon fiber and set up the cat whiskers to drive an opamp, complete with a bit of capacitive smoothing so the opamp could match the speed of the grooves. It worked well except that the track on which the arm moved was resonant and sloppy. Reducing the mass of the arm was a big deal though. I think that Audio magazine article really does itself an injustice by referring to ’pivoted’ as opposed to ’radial’ arms- in that regard it makes almost no sense unless you know that they mean ’linear tracking’ when the word ’pivoted’ appears.... |
@bukanona tyray, in my opinion antistatic effect is very small and it’s more advertising gimmick. I am a little bit confused why none of MC cartridges uses brush. Maybe there is some interference. For high compliant ones it should be very OK...Now that you mention it, I do remember before the market had ’standard’ stylus cleaning brushes, cleaning fluids and dust covers, folks just used to wipe the vinyl with a cotton cloth and blew on the ’needle’ or just used nothing at all, which I do remember caused a lot of static and not to mention dust accumulation on the needle. I’m thinking we both are right though, the antistatic brush also could be thought of an antidust brush too. It must have been a ’revolution’ at the time it came out as it took some years before for the practice and use of ’record cleaning’ became an audiophile practiced standard. I think the Shure brush patent was such a Shure engineering statement it became synonymous with the Shure brand. Stanton MM carts also uses brushes. Maybe it was just a MM Thing? |
"
we can assume its compliance is stiffer than original, and I also pointed out that I used a very light weight headshell on the FR64S.. " WE?, wrong because is you whom assume it and in the other side even with a low weigth headshell the resonance frequency is really low. "" I don't know this to be true, but it is a possible explanation, because the mass can dissipate energy as heat. I took your (dismissive) response as evidence you disagree with the idea of mass damping .. "" That is always the " problem " with you: always are assuming " things " for other people. Obviously those were not my words but only what is your hyphotesis with no true value at all. Ignorant?, you can read my posts in this thread and I did not use that word in reference to some of the audiophiles that posted here. Enough, period. R. |
