Cartridge Loading for a phono pre amp

JC.
,,,get a life.

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 issues .

This statement does not support Raul's assertion: it says something quite different!

Dear @imhififan  : Thank's again for your advise. The answer to the main subjects in this and other threads ( elsewhere ) where just in front of me and never seen it,. Go figure ! Nothing like those first hand tests 

Good ! !

And did you choose 100 ohms, 47 kph, or something in between?

@holmz

Sorry for the late reply, finally get the tax return filed! 😌

For the Denon DL-103, I chose 1kΩ, because I don’t want to use a too low resistive load to load down the cartridge and at the same time don’t want to use a higher resistance to eliminate those unwanted RFI get into the phono input.

IMO, since RFI is not the music contents, why not apply a correct amount of resistive load to damp the unwanted RFI even though the phono stage can handle it.

@imhififan thanks mate!

On the subject of the tracking… the RIAA sort of works in our favour as the stylus does not have to move as far with the curve sloping down… maybe that lessens the cart getting stiffer for the high freqs? (It is but it hardly wriggles)
