Cartridge Loading- Low output M/C


I have a Plinius Koru- Here are ADJUSTABLE LOADS-
47k ohms, 22k ohms, 1k ohms, 470 ohms, 220 ohms, 100 ohms, 47 ohms, 22 ohms

I'm about to buy an Ortofon Cadenza Bronze that recommends loading at 50-200 ohms

Will 47 ohms work? Or should I start out at 100 ohms?

I'm obviously not well versed in this...and would love all the help I can get.

Also is there any advantage to buying a phono cartridge that loads exactly where the manufacturer recommends?

Any and all help would be greatly appreciated.

Thanks in advance.

Dear @krelldog : I agree with the gentlemans behind 100 ohms very good point to start and I think you will never have to change it. Of course that it's your particular audio system items whom will have the " last word " through your listening experiences over the time.

Btw, very good system you own.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Thanks for all the great insight. I'll start at 100 ohms and set the gain at 60 db's. Hopefully that will sound amazing.

Raul- Thanks for your kind comments.

If the cartridge needs loading below 47K its an indication that the preamp is not stable with Radio Frequency Interference (RFI) at its input.

The loading resistor is not for the cartridge, its for the preamp.

This is because the cartridge inductance combined with the tone arm cable capacitance forms a tuned RF circuit- which is energized by the cartridge signal. It can be over 30 db higher than the phono signal- thats about 1000x more powerful!
The loading resistor detunes the RF circuit, preventing the RFI. The problem is that in so doing, 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.

A side problem is that preamps that have problems with RFI are also far more likely to produce ticks and pops. This is often due to poor overload margin, since a signal that is 1000x more powerful can overload the preamp. The other reason is that the phono circuit can be unstable and react poorly to RFI; either way if the phono section does not have these problems, a side benefit is far less ticks and pops- you may not ever hear any on an entire LP side.
Many phono preamp designers don't realize the RFI implications and so don't know to make sure their circuit is immune to these problems. So instead you see loading switches and the like...



On that thought...all I can say is that my phono preamp (Plinius Koru) is very highly reviewed. I'm currently using an Ortofon Quintet Black. My settings are 22 ohms and I'm using 66 dbs of gain. The sound is spectacular...no issues. These are the only settings I've used since purchasing the Koru. Thus my apprehension with where to set the Koru with my soon arriving Cadenza Bronze...BTW it will be attached to my new VPI Prime Signature. I'm sure I can find the right settings...just really looking for a starting point.
The best starting point to check your cartridge and phono stage is 47k Ohm for MC (take in count what Atmasphere said)
