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!

Calculation work ONLY if you know dynamic compliance at 10Hz. 

If you cartridge is Japanese then compliance most likely stated at 100Hz in the manual (even if they do not mention 100Hz). In this situation you have to multiply this data on 1.7 at least (to convert it to 10Hz).

Buy a HI-Fi NEWS TEST LP and measure your actual tonearm cartridge combo, you will see where is the resonance frequency really is. 

" Tracks 2 & 3: Cartridge & Arm, Lateral & Vertical Resonance Test
These two tracks are used to test the resonant frequency or your tonearm and cartridge combination in both the vertical and horizontal domains. These tracks offer both a visual and auditory indication of the resonant frequency; the stylus will “wobble” and the test tone will warble. A resonant frequency between 8 - 15Hz is ideal.'"
