@elrod, OK- just so you know, although the MP-3 is a fully balanced preamp, it can be operated with a single-ended output. We usually have to set it up to do that, since balanced and single-ended are basically incompatible. We set it up with a switch so either RCAs or XLRs can be used.
Your phono is of course a balanced source, so the MP-3 can take advantage of that while still having the single ended output.
