Optimal Loading for Shelter 501 mk2


Hello all you Shelterphiles! A friend of mine is building me a preamp, and will set up the phono stage for my cartridge. I'm using the Shelter 501mk2 and a OL Silver Taper with its stock cable. Can anyone tell me how I should configure the loading on the phono stage?

Thanks, Peter

For what it's worth, I use a Shelter 501 Mk2 into a Plinius M14 phono stage which has adjustable loading "on the fly" with a knob on the front. You can select, 47K, 1K, 470, 100, 47 or 22. To my ear 47K is the best with the sound becoming consistently more compressed as I decrease from there. Shelter also recommends 47K ohms for a high gain phonostage.
It's on the data sheet they provided with the cartridge.
It says,
Recommended load impedance:
step-up trans within 20 ohms
head amplifier within 100 ohm
high gain EQ-amplifier within 47k ohm

I am using a high gain amplifier whereas Doug uses the Bent transformers
