I just bought Klyne 7 PX 3.5 which has not separate inputs for MM
and MC carts. But there are two ''banks'' with switches one of which
is for the amplification (36, 50 and 63 dB) and the other for impedances
and ''frequency contour'' by which one can select 47Kohm for either
the MM as well the MC carts. What we think off as MM phono-pre can
be adjusted or sellected by chosing for 47 K ohm impedance and 36 dB amplification. So just one (pair) of input and outpur connectors is sufficient.
