Cartridge Loading for a phono pre amp

Again: " To claim that the loading affects the measurable frequency response of the cartridge is bogus. "

He not named " bandwindht ".

You said: " less able to trace high frequencies. " any cartridge that's " less able " to trace HF change the frequencies where is less able to pick up the grooves information. But the issue is that you can't prove it with true facts/measures.

 You follow with your tale at Munich but in at least 3 different threads in different internet forums where you, JC and I participated about and where you posted your same " tale " he never confirmed that agree in that " less able to track HF ".

With out facts and confirmation for me all that is a lie and false as Wayne proved.

You were not in Munich, plain and simple.

JCarr did not address the topic of high frequency traceability one way or the other. I recommend you set up an LP mastering lathe as I have and you can sort all this out easily enough.

If you are saying that by making the cantilever stiffer that its ability to trace a smaller and smaller waveform in the groove, requiring the stylus to move faster and faster against that increased stiffness, and somehow its ability to move that fast is unaffected, be my guest. But on a very basic level, the idea has no merit.

In this context, is there any relationship between cartridge bandwidth and cantilever stiffness? It seems that as the load-induced stiffening increases, the more reduced the bandwidth becomes.

Thanks Ralph.

It seems that way slightly, but there is an electrical component as well as mechanical.
And the stiffness may be more like a phase shift than an amplitude decrease??

we need a real physicist here.

@noromance : " While mechanical impact does occur as a result of electrical load- there is some back emf necessarily generated by the signal current that affects the mechanical motion, but a quick back of the envelope calculation using Lenz’s law and the 10uH cartridge suggests a 2 orders of magnitude difference between the generated signal and the back EMF for a 100 ohm load at 20kHz- certainly not enough to cause tracking issue. "

With no tracking issues, that Wayne measured and JC wihte papers shows, bandwindth/frequency response is not affected.

The OP, you or any one else can load their cartridges witrh the impedance that in each one system " sounds " the best with out worried on that electrical/mechanical load issue that no knows system can " detect " and even direct measures can’t. So why distress about? makes no sense .

Btw, @whistleraudio  posted: " we need a real physicist here. " and is rigth: he need it.
