MM input level: 2.5mv
MC input level: 0.5mv
MM input impendence: 47k?
MC output impendence: 100?
MM signal to noise ratio: 91dB
MC signal to noise ratio: 86dB
Output impendence: 100K?

One day I will know what all this means!

One thing this means for certain is that you shouldn't buy this
amplifier. At 100k output impedance, if you connect it to a power
amplifier with a cable whose capacitance is as little as 100pF, the
response will be 3dB down at 15kHz. This is most definitely NOT a
competently designed amplifier.

The guy cannot even spell impedance correctly.

We engineers would all realise the output impudence
would be 100 ohms, or 1,000 ohms.
