Yes Archie, no difference. From distortion at the botttom to very quickly a single volume that never changed. Thats the ZMC1. Now I`m thinking that the ZMC3 @ 12X gain but with a differnet impedance match might be better suited. [
ZMC1
For low output MC cartridges
1:20 ratio for use with 3~25 ohm cartridges.
ZMC2
For high output MC cartridges
1:10 ratio for use with 3~100 ohm cartridges.
ZMC3
For high impedance MC cartridges
1:12 ratio for use with 25~100 ohm cartridges.
My Benz LP`s cart is 38 ohms.
