A Lino C 2.0 + ZYX Ultimate 100 ( impedance 4 ohm ) is my current setup. The adjustable gain is set at +12db which achieves approximately 75 db with the 4 ohm input. Rob at Channel D had cautioned that using the highest gain may cause distortion due to overload margin. However, as I am also using a Lightspeed Passive Attenuator, I need all the help I can get in the gain department. My sense is that with my setup, an impedance of 4 ohm is really the upper limit of MC cartridge choices.
I have therefore been extremely interested in low impedance MC's, My Sonic Labs, Transfiguration, Lyra.... and of course Mutech. I think Mutech makes part for Transfiguration and it uses parts from My Sonic Labs. While I am not in a position to upgrade or acquire a new cartridge right now, I am especially interested in Mutech. It seems that the RM-Kanda Hyabusa is an export model, while the RM-Kanda is the top of the line retailing at $6,000. But with impedance or 2 ohm, it should work very with the Lino C.
