I would opt for someone well schooled in electronics and its application to audio, who just happens to have 'good ears'.
IMHO musicians rarely have clue about what makes an audio system sound good to an audiophile, they are much more interested in the music itself and their instruments. My daughter is one, has perfect pitch, plays several instruments quite well, and wouldn't know what a 'soundstage' was if it bit her in the ass, let alone some of the other hallmarks of a great audio system (and couldn't care).
Think for a moment from the prospective of a musician - where is that person when playing. When are they ever in a position to judge what the music they are making sounds like to others who are not part of their group. A dubious credential for making electronis IMHO.
