Re: balanced sources

FWIW (2 pennys?) any signal source that only inverts phase when you reverse the connections is a balanced source (that is to say, it does not hum and buzz like the dickens). Phono cartridges, tape heads, microphone elements and anything with a transformer coupled output are all examples of balanced sources.

This is why if you run a phono cartridge single-ended, you have that funny little ground wire that no other single-ended source seems to need. If you run any balanced source as single-ended you have to do something like this.

The MP-1 and the MP-3 really don't care if you run the phono single-ended or balanced, it will work about the same, but *you* should care, because running the phono signal balanced all the way sounds a bit better. Why not do it if you can?
