Jamis, awesome theater you have there.
I hope you don't mind but after another poster in another thread mentioned using your setup as reference for his own and linked to your shots, I noticed the dust orbs shown from the flash in some of your shots of the ceiling mounted PTAE3000u and commented that they could lead to dust blobs. We all have dust, I wasn't picking on you, its just that one of your shots has a lot visible, and in that other thread there are people arguing that the PTAE3000U is more prone to it (which I think is hogwash, any non sealed optics engine design is susceptible to them).
In A/V reproduction accuracy, there IS no concept of "accounting for personal taste/preference". As art consumers we don't "pick" the level of bass, nor the tint/brightness of a scene's sky, any more than we pick the ending of a novel or Mona Lisa's type of smile. "High fidelity" means "high truthfulness", faithful to the original artist's intent: an unmodified, neutral, accurate copy of the original master, ideally being exact and with no discernable alterations, aka "transparency".
