I have a BMC MCCI Signature ULN phono stage listed on Audiogon now that is fully balanced in and out. It was one of two phono stages I settled on after considering a number that were suggested to me by the community, and I documented it on this thread.
If you have a moving coil cartridge, it is well-worth looking into. My reason for selling it is that I recently became a dealer for other brands and cannot afford to keep it given the inventory I am accumulating. Reviews on it are all very positive as well.
