A question of loading...

atmasphere :  ""   If what you say (that loading the cartridge has no effect on the stiffness of the cantilever),... ""

that's not what I'm saying even if I did not explain it in the rigth way.

What I'm saying is what i posted:


"2   stiffness to the cartridge cantilever enough to mistracking. ""

the key in that statement is: " enough ", this is what I'm saying and in his technical words Wyn too.

Two years ago here and in the other forum I told you the same: how much current has to pass through to stiffness the cantilever enough to the cartridge mistracking?

In those oboth forums I told you that for the mistracking could happens the cartridge compliance has to change a lot of compliance units and here in the Etna/Kuzma real example you need to pass from 12cu to 7cu to be out of the ideal resonance frequency range but that does not means for sure that will be a mistracking down there.

The issue is that mistracking not that cantilever stiffness. It's you who need to prove with measures that can gives the rigth answer to that question I made it two years ago and that you never answer.

The issue that's false is that exist mistracking when more current running through the cartridge.

I don't think anyone has stated that this leads directly to mistracking.

The issue is that mistracking not that cantilever stiffness. It's you who need to prove with measures that can gives the rigth answer to that question I made it two years ago and that you never answer.

That is probably because I never stated anything as you seem to be implying here. I think this is probably because I use English as my main language and you don't; this apparently has resulted on a misunderstanding on your part.

What I *have* stated is that loading affects the stiffness of the cantilever. And further, that this could affect its ability to trace high frequencies. But I can see that this statement can really be misinterpreted. Note the use of the conditional 'could' in the sentence, as well as the rather ambiguous 'high frequencies'.


So let me put this another way. Most cartridges easily go to 40 KHz, I've measured this by cutting signals that high on my lathe and playing them back. Now we know that loading down the cartridge makes the cantilever stiffer. Are you saying that if the cantilever were ***easier*** to move, that it was less stiff, that it would not trace high frequencies as well? If the answer is 'no' then you have to accept that if you make it stiffer, at some point (maybe well out of the audio band) the ability to trace higher frequencies might not be as good.

Now the other aspect of cantilever stiffness is the mechanical resonance that the arm/cartridge compliance system exhibits. Making the cantilever stiffer is another way of saying that you reduced its compliance. Are you saying that by reducing the compliance of the cartridge that such will have no effect on the mechanical resonance? If no, then you accept that the mechanical resonance is affected by the compliance of the cartridge.

In 2018 thread where wyn posted and before the first wyn post you posted not one but twice:

""" When you load at a very low value (like less than 100 ohms) its possible to reduce the cartridge output and also decrease high frequency tracking abilities. ( Btw, wyn runs his mandake at 60 ohms and performs fabolous. Obviously no tracking issues. )


"" the cartridge is asked to perform more work as it has to drive the lower resistance. This makes the cartridge cantilever stiffer and less able to track higher frequencies. This is why the resistor can act as a tone control. ""


Curious that in that thread that after the first wyn post there you left alone almarg ( who was supporting you. ) and you did not post nothing again about that cartridge tracking issues not even when wyn posted was FALSE because he measured.

In the other side and in the Etna/Kuzma resonance frequency it needs 3 compliance unit to change its frequency resonance and instead of 12cu we need 10cu. Again how much current is need it to happens that?

R.

Instead 12cu we need 9cu. Frequency pass from 10hz to 9hz that's not enough for the cartridge been affected in its tracking abilities and the tonearm/cartridge behavior is not altered.

Other curious things that happened with you in those threads in 2018 is that in both threads JC participated and in both threads he not supported with a post the conversation you said took place in Munich when talked about that low load impedance consequences. Weird.

Curious too that JC even that he participated in the Agon 2018 he posted nothing when wyn posted FALSE about tracking.

Such is life.

I think is enough. If we learn something through this thread good and if not maybe helps to confirm what we already knew. All we win and no body defeated.

@rauliruegas  I have played around with the loading on several different MC's in the past..the results were not anything that could really be anticipated. BUT one thing that was never in question, was that the cartridge was mis-tracking in any way...which IME is very easy to hear! 
With my current Lyra, the tracking is spot on and is certainly not effected by the load applied at the phono stage, YMMV.
