Out of interest, what the input impediances of the amps in question ?
That could well be making a difference. And maybe input capacitance,
depending on the circuit of the phono stage.



I'd also be interested in the output impedance of the pre-amp. Does it
use
cathode followers?


That was my point...


From http://www.mei-xing.com/doce/pro20.htm

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!
