Increase tonearm mass to match low compliance cart


I have a Rega RB250 which has an effective mass of 11 grams.
I want to try a Denon DL-103R cartridge but the 5cu compliance
of this cart doesn't match with the tonearm mass.

I heard I could use brass bolts to affix the cart to arm, the weight
of the brass increasing tonearm mass to nudge resonance into
acceptable frequency range.

Has anyone tried this? I hear Denon's compliance specs might be
lower than reality. I'm a newbie, can anyone recommend an effective
mass that will work well with the DL-103R?

Binar, there have been many posts concerning the 103R's advertised compliance. Most believe it is higher though still a LOMC. I've used the 103r with a RB250 and RB300 with great results. You should be just fine without doing anything special.

I do recommend looking up TWL's tweak which uses some fishing weights as a means to improve stability of the Rega arms. Very cheap but very effective tweak.
