    I have a lot to learn about compliance.

    Could someone assist me in determining if the following cartridge would match well with my Rega RP6 RB303 tonearm?

    Ortofon MC-3 Turbo Specifications
    Output voltage @ 1000 Hz, 5cm/sec.: 3.3 mV
    Channel balance @ 1 kHz: < 1.5 dB
    Channel separation @ 1 kHz/15 kHz: > 24 dB / >15 dB
    Frequency range @ - 3dB: 20-30,000 Hz
    Frequency response: 20-20,000 Hz + 4 / - 1 dB
    Tracking ability @ 315Hz at recommended tracking force *) > 70 µm
    Compliance, dynamic, lateral: 13 µm/mN
    Stylus type: Nude Fine Line
    Stylus tip radius r/R: 8/40 µ:m
    Equivalent stylus tip mass: 0.75 mg
    Tracking force range: 1,8-2,2 g (18-22 mN)
    Tracking force, recommended: 2 g (20 mN)
    Tracking angle: 20°
    Internal impedance, DC resistance: 100 Ohm
    Recommended load impedance: 47 kOhm / < 500 pF
    Cartridge body material: Noryl
    Cartridge color: Black
    Cartridge weight: 4.1 g

    Thanks in advance!

    The Rega arms are about 12g eff mass. So according to Cartridge Resonance Evaluator resonans will be at 10 - 11 Hz ant it is OK. But I do not find the height of MC-3 turbo. Regas are low profile carts, about 14 mm, so if the height differ, you will need a spacer under tonearm to get right VTA.

    Thank you! I do have a spacer and I'm going to experiment between the 2mm & 4mm spacer settings.
