Gregg, I recently heard a recording that placed a dog barking 40 feet behind the listening position. Can't remember the song it was on but I had to rewind it to make sure I wasn't going crazy, hearing things that couldn't have possibly......well, been possible.I think we have to remember that audio soundstage is part illusion. Imaging is not limited by the size of the room. I have heard systems recreate the sound of a dog barking my neighbors yard. or a car blowing its horn down the street. It is entirely possible that the perception of the soundstage can expand beyond your walls. i am currently evalauating the Sennheiser HD 800s headphone. On Stravinsky Firebird Suite I can perceive a good sense of the size and scale of the hall. Aided by my eyes because it is a video.
I don't think you'll get an exact replica but you can come close. Remember Harry Pearson(the late publisher/editor the absolute sound) using the Infinity IRS in a tiny room.
Since I sit about 10 feet away from the speakers, that placed the phantom image 50 feet away from the speakers.
I just got done listening to Eric Kunzel and the Cincinnati Pops play , "Olympic Fanfare". As the goose bumps were swarming all over my body, I thought of this thread and revisited it.
My thoughts on this have not changed. I hate to say it but I would be so bold as to say that if you can't fit a 50 foot wide orchestra in your small room, then something is amiss in your system.
I say this not to cause strife but to let folks know that it is entirely possible, that if they cannot emulate an orchestra in a small room, it's time to start working on things. Strive to achieve better. At least try.
If your walls and speakers do not completely disappear, then that system is in need of some work. To me, this is an extremely important aspect to achieve the spatial locationality cues needed to pull of phantom images from all over the place.
