Help me understand compliance!


Hello all,
I have a Rega Planar 25 with an RB-600 tonearm. I am at a loss with words like compliance. What weight/ compliance combination is correct for a cartridge for this tonearm? I’m looking for the correct weight and compliance so I can go shopping. Also, any recommendations/ experience with cartridges on this rig would be appreciated. The rest of the system is a Conrad Johnson premier 11a power amp, sonic frontiers sfl-1 preamp, B&W 804s speakers and a MF lx-lps phono preamp. Cables are Musica Bella emberglow speakef and ic
thanks in advance!

If you have a heavy tonearm you want a stylist system that can handle the mass of the tonearm. Or if you have a light tonearm you want one that moves easily. Compliance is just a way to match the tonearm weight for best performance.  
The RB-600 is a  medium mass tonearm at 11.5 grams. This article explains cartridge and tonearm matching.
