Just make sure to switch back to 100pF once your ears and your brain are relaxed and refreshed and try again.Maybe because it was set to 100 before I was made aware that there is a mouse piano I can play with. With other words, the reason we got here was that it did not sound right when set to 100 - all this given my reconstruction of events past is accurate that is.
I think the next number would be 300. I don’t think it goes below 100. I’d have to check again though. I was tired when I did that.
Just remember that neither Oftofon nor Pro-Ject can tell you exactly which value will sound best. And that's not because of the usual "everyone's hearing is different" talk but simply and technically because they don't know how much input capacitance your turntables cable will add.
As I said, 150-200pF of cable capacitance are typical values, but it could be noticeably less ... or more.
If the cable is detachable from that Technics I hope you kept I as short as possible! Too high capacitance values can lead to a massive peak somewhere in the treble region >= 5 kHz (which might sound like better detail at first), but followed by a steep and massive downwards slope right after the peak. You might loose all the really high treble.
Some pickups are more sensitive to capacitive loading than others. The internal inductance and interna resistance of your Oftofon are on the lowish side of normal, which is good. But still, usually lower input capacitance simply results in a more linear frequency response.
