The parameter table gives ≈0.2Ω (32Ω); the output impedance panel (product details, image 11) gives <0.2Ω (32Ω), and the comparison table (product details, image 4) ≈0.2Ω. The catalog uses the parameter table.

The AP analyzer charts show SNR 108.458/108.785 dB, noise 5.692/5.455µVrms, THD+N 0.002505/0.002304%, crosstalk −72.804/-72.968 dB and dynamic range 104.376/104.880 dB (Ch1/Ch2); the parameter table gives ≈107 dB, ≈5.7 µV, ≈0.0030%, ≈-71 dB and ≈104 dB. The catalog uses the parameter table.

Is it enough for your headphones?

JCALLY rates the JM6PRO 2 at ≈135 mW into 16 Ω. Below is how much of that is left to spare for each kind of headphones when you listen loud, with peaks at 110 dB. A figure marked est. is worked out from that rating.
