Help Needed Designing an "Amphitheater-Like" House

I thought amphitheaters were outside with no walls or roofs?
The idea was to make sounds audible to all listeners without the aid of amplification.
Maybe what you really want is an arena rock venue? lolol

Indeed, I chose the wrong word to describe the structure. 6550c, you are brilliant for discovering my mistake! I REALLY meant to describe a "music hall" type of structure, but before I had the chance to correct myself, YOU did it for me! Thanks! Hey, you even managed to infer that I listen to arena rock, which I presume would mean that I lack true audiophile taste. Perhaps you listen to "Aja" and "Dark Side" a lot, or better than that, "Classical" (groan) music! I wish I was like you!
It's o.k., I found out about a book that goes into room acoustics; and I will be using that for information. It's a shame, because I could endure a bunch more abuse if I just hung around here!

Oh, hang on! In my counter-slight list of music I suggested 6550c listens to, I mentioned "Dark Side". This could create a situation where someone could deconstruct my irony and point out that Floyd could be considered arena rock. So I will restate:
Perhaps you listen to "Aja", watered-down "Jazz" featuring expert, annoying female vocalists on recordings with superlative production value, or better still, "Classical" (groan) music!
Alright, I'm sure there's other stuff I'm messing up, so have at it.

What ever you say, Mr_stain. Remember, in the end, it is all in the brain. Some of got one, some of us didn't. The brain is the ultimate transducer, so don't forget to work on that a bit too. okay? lolololol!!

Confusing response, and not sure why I came back; but trust that this will be my last post on Audiogon Forums forever. I stopped using Forums on other sites because the nastiness factor really comes out in people when they are separated by long wires. Anyway, the trouble with this Forum, which 6550c's remarks kind of exemplify is the undertone of snobbery that seems to come up again and again. People regularly show off their 'superiority' and brag about what they own. And of course, the emphasis is on physical equipment rather than ideas. For instance, in the various categories listed on the Forums page, the subject of "Music" wins about 5000 posts (about the same as "Tech Talk") and falls thousands of posts short of things like amplifiers. Then, upon reaching the "Tech Talk" forum page, one is offered some general things to comment on under the heading, "What do you think?" In that list, two threads stuck out to me in particular: "What does your system retail for?" and "What is Musicality?" The former thread is older, thereby deserving its post count which is a full 6 times the amount of the later, but wait..... people keep posting on the $$$$ thread while the "Musicality" thread has remained dormant for several months now.
WHERE ARE YOUR PRIORITIES, FOLKS?!
There is a thread within the "Misc. Audio" section's "What do you think?" header entitled (get this), "What time do you wear?"
GET LIVES. I'm out, peace....
