Cartridge Loading for a phono pre amp

Think this may be right:
 

If 100 ohms loading is too low and 470 ohms is too high, you can turn on both 470 ohms and 560 ohms to get approximately 250 ohms loading.

Certainly will be the closest.

This is something you need to just try and see for yourself—there is no “correct” value.  Given the quite high output of the cartridge, the 24 ohm source impedance of the cartridge reported by imhififan sounds about right.  I would expect anything from 47k to 470 to be the best sounding.  But, if the cartridge still sounds bright, or thin, or in need of more bass, an even lower value might sound better.  I would only be surprised (and mildly so) if 47 ohms is the value thar sounds best.

I've always found Benz cartridges are happiest with higher loading.

I would start with the 1k load and work down. Experimentation is needed though.

You won't hurt anything by trying different loads.

Why not try 47K? I believe Mr Luschadek (founder of Benz) recommended that. I ran my Ebony L on 47K which sounded more open. I run my Zyx 4D that way also. From my understanding of Ralph’s (Atmasphere) explanation, the loading or not loading is dependent on the phono stage’s stability. Try it on 47K. Then try it on Benz’s recommended loading. See which one you like better

Thank you all for your responses.  All this info is very helpful in getting started.

BEST TO YOU ALL!!
