Hi,
I recently got a Shure V15 VxMR.
You can read about my initial dissapointment with it here:
...and here:
Lots of folks on various forums suggested that the capacitance might be the culprit.
Shure recommends capacitance load of 250pF.
My phono preamp's (Graham Slee, GramAmp 2 SE) capacitance is 150 pF.
My SME 3009 S2/imp is rewired with 40 cm of Van den Hul MCS - 150 M cable.

capacitance is not stated
Cable from tone arm to preamp is Van den Hul D - 502 HYBRID
http://www.vandenhul.com/cable/d-502-h.htm
capacitance is 75pF per 1 meter. I have 1.2 meters cable lenght, so it should be 90pF
Together with preamp's 150pF it makes it 240pF, leaving a reserve of 10pF for tone arm internal wiring, which is unknown but I guess it is higher than that.
Is going a little bit above 250pF, a huge, make or break difference? Can it be the cause of my problem with the Shure?
I could cut in half my Van den Hul, thus lowering it's capacitance - lot cheaper than losing money on selling my V15
But I wouldn't like to ruin a perfectly good cable, just to discover that nothing had changed...
What would happen if I intentionaly go significantly lower than recommended 250 pF (cutting the Van den Hul to only 30 - 40 cm)?
Would I get some aditional boost in the treble?
Some folks said maybe, but some suggested different:

What do you think?
Thanks,
