Then factor in the practical issues - you NEED a great space for jazz, period. It's only three or four instruments, but they all play in the same space - and you can't really put the bass player on the other side of the room because he and the drummer near to be able to have a clear line of communication. I work with a pianist that's so dynamic, I have to set up four mics inside the lid - 2 closer to the soundboard for when he plays quietly and 2 a little further up for when he's smashing the keys because the piano starts to project differently and the sweet spot for the placement changes. One moment you have tons of headroom, the next moment your overdriving your preamps. For one, the playing is extremely dynamic, so one moment you have no bleed problem, the next you do.
