Axelwahl, the Manley Steelhead has plenty of gain in its MM stage (up to 65dB) to run the XV-1s cartridge without the extra gain of the step-up autoformers. In fact, I ran the XV-1s through the MM inputs at the time I was using the Steelhead as my reference phono stage with the XV-1s.
I preferred the sound of the XV-1s run through the MM inputs as opposed to using the step-up autoformers that are in the signal path when using the Manley's MC inputs. The sound using the MM inputs was more transparent and immediate, whereas the autoformers seemed to cast a subtle veil.
