My record-player  Beogram 5651 w/MMC5 pick-up is connected to a TerraTec iVinyl PhonePreAmp .

It has a setting for input capacity ("adjustable in three stages (100 pF, 250 pF and 430 pF") - and I have absolutly NO CLUE to proper settings...

Their manual says: "Input-range selector switch Please refer to the technical documentation of your phono pickup system for the rec-ommended input capacity range for the preamplifier. Then set this selector switch to a value that best matches this range."

 Anyone who can help me?

430pF should be the right level. I have been searching for one of my spec sheets but have only found my SoundSmith one so far!! But all B&O cartridges have the same requirements!

Take it all back! Just found my MMC20CL box with data sheet and it suggests 220pF! 

Thanks Peter!

By a coincident, I also found the spec for the MMC 5 R pick-up today, and it says: Capacity <= 400 pF for all MMC {5,4,3,2} R pick-ups.

I assume that 250pF is less than 400pF :-)

Anyone got  an idea of what's the difference in the sound?

Not me, but it's quite safe to experiment, and simply use the setting that sounds the best for you. I would expect the load capacitance to mainly affect the higher frequencies, with 400 pF and above sounding a bit dull.
