I have and still use a 1000. I asked this question of Zanden and was told no luck now with any 1200 having an MM input but the 120 (SS) can have one of the two transformer pairs removed for an MM input. The 1000 also has the mono input and loading choices.
I don't think he'd mind if I quote this from him email: the primary differences between the model 1000 and the later 1200 series is the tube circuit design which incorporates fixed bias. Whatever sonic improvements you may achieve by having the "perfect loading" for your cartridge [via SUT] they are almost always outweighed by the sonic improvements of fixed bias. The 1200 series has both a pair of low and high impedance step up transformers. For the vast majority of cartridges any sonic benefit to having your own custom step transformer is minor compared to the benefits of fixed bias.
This phonoamp looks like a piece of jewellery and so pretty. I wonder how does it perform in slam and bass compared to the best of the solid states like Boulder, CH Precision etc? Could any users share their thoughts?
