Before I do any subjective listening, I play some music tracks that are well recorded, mixed & mastered. For me, that is commercial recordings... specifically, Steely Dan, Royal Scam - MCA Records MCAD-31193; Counting Crows, August and Everything After - Geffen DGCD-24528; Bonnie Raitt, Luck Of the Draw - Capitol Records 07777-96111, etc... That gives me a reference from which to judge whatever recording I am listening to.
What I am trying to say is, that you may need some good reference material to use for comparison to figure out what you really like. When I find an audience recording that I think holds up well against a well recorded, mixed and mastered commercial recording, I save a track or two from it and add it to my reference library. If you do that, that library will be specific to you, reflecting your preferences. It may make it easier for you to determine what mics/ pre-amps/ etc... you prefer.
