Here is a breakdown of voltages into the Belari:
Denon DL103R using 1:36 tap on the Cinemag:
The cartridge sees a 40 Ohm load. Voltage is 0.25mV after the step-up this is close to 10mV, which may almost overdrive the Bellari (effective gain is about 30dB due to the step-up alone). After the 30dB gain Bellari you have 0.4V which might still not be enough to drive your amp.
Denon DL103 using 1:36 tap on the Cinemag:
The cartridge sees a 40 Ohm load. Internal impedance of the 103 is 40 Ohm so that the available output voltage is half of the 0.4mV given, i.e. 0.2mV. After the step up you have about 8mV output.
