Both Revelation phono stage preamps are identical to the original Revelation phono stage preamp with the exception that the Revelation M is now lower noise, and the Revelation C is for moving coil.
Revelation M phono stage preamp is meant for moving magnet, high output moving iron and high output moving coil cartridges while the Revelation C phono stage preamp is meant for conventional (low) output moving coil cartridges.
Both versions are switchable-equalisation-curve versions of the Reflex M and Reflex C phono stage preamps.
