"I am there" vs. "They are here"


Hi,
all of us in this hobby have heard the exclamation "I'm there" or "they are here!" a counless number of times. Usually these remarks are issued forth when one's audio system has made a sonic leap in the direction of naturalism.
However, "I'm there" and "they are here" are clearly two very different remarks.

Would anyone care to describe in detail what about the sound of a great audio system that inspires the listener to make one remark rather than the other.

Which one is a higher compliment?

Thank you,

David

I have a 7' Steinway B sitting behind my speaker plane, set as a 7.5' nearfield triangle. Whereas "I'm there" somewhat often with orchestral sources, all too often pianists (and their jazz trios) "are here". I can even jiggle with my separate Pass Aleph P gain controls to have a chanteuse slide up closer and lean into the piano belly as I imagine ME 'comping her! At this point WHERE am I?
If she's a great looker, I'd be crawlin on her too !!
At that point, I'd "be there" !!
They'd probably throw me "off the stage" !!
At that moment, I'd be "outta there" !!!!
Perhaps 'you are there' will become possible with properly-done multichannel audio.
Subaruguru-

In your post back in '01 you touched on a subject that I had been puzzling over for some time.

Pinpoint imaging I felt would be the mark of an attractive 'I am there' sound. It turned out not to be the case for me. It seemed rather unnatural. Having been to many different live performances, I never noticed pinpoint imaging in any of them I could recall.

The last few months and a number of live shows with paying much closer attention verified my gut reaction. No pinpoint imaging seemed to exist. A full live sound, not pinpoint. A recent amp had an uncanny pinpoint imaging ability, and it actually (slightly) drove me nuts as it refused to convey the fullness of voice required as being in a natural setting. It actually sounded a bit thin.

Anybody else notice this? or am I just wacky...
