At best I'm trying to recreate the sound in the mastering studio which may or may not have a basis in real time musician performing.
I would agree with that. However, to get the sound of the master tape, you need the master tape. Everything else is a copy. On the other hand, there's excellent copies out there, like very first pressings, white label promos, etc. Perhaps with mostly imperfect recordings and let's face it, there's no such thing as perfect equipment, quite a few audiophiles are the proverbial cat trying to catch its own tail. I plead guilty to this as well. You really have to sit down and spare a moment to think what you're after in putting together an audio system. This stuff isn't cheap, as you know.
