Soundstage, Imaging, Detail & Presence??

No need for mysticism, many wise listeners have learned to trust their precious god given ears. Much of audio and acoustics can`t adequately be explained by science amd measurements(yet). Fortunately we have are ears which have evolved and developed over millions of years to show us the way. Scientific explanations often lag far behind what people experience in many endeavours and daily living(examples are to numerous to list). As of now our ears are the best tools we have when it comes to determing sound quality.

"I suspect the speakers and acoustic environment of the room have far more to do with presence than tubes v. solid state"

I agree, but I also agree with Charles1. It all needs to work together and listening trumps measurement or theory.
btw: Neither tubes nor SS are digital.

I'll take a crack at it...

1. Imaging: The perception of individual instruments/voices in physical space, including their position, boundaries, and size.

2. Soundstaging: The perception of the overall layout of instruments/voices in physical space, including the spatial dimensions and ambient characteristics of the recording space.

3. Presence: The perception of "realism" or "lifelikeness" of instruments/voices, whether in the form of "they are here" or in the form of "you are there."

4. Detail: The perception of resolution, whether real or apparent.

As I have defined them, imaging and soundstaging are interrelated, and presence and detail are interrelated.

We all speak the same language...don't we?

Soundstage: The illusion of looking at an actual stage, some are wide or deep, some may me very small, but your system should duplicate the actual stage.
Imaging: A systems ability to let you see where singers, instruments, etc are within the soundstage. Up close, far back, a bit to the left and so forth.

Detail: To hear the resonance on a violin bow, not just hearing the violin, to hear the air moving through a saxaphone and real detail is hearing going through the sax . Also very define edges on where placement of instruments are on stage, these all show detail.

Presence: To feel that what you are listening to is in your room, or if you can close your eyes and imagine your presence there. Presence is Realism.
Someones examples should click with you.....If not, time for some new gear.

Charles your post is full of contradiction,

No need for mysticism

and

god given ears

Doesn't the idea of god invoke mysticism?
Then you go on to suggest that our ears have evolved. Weren't they given to us by god? Or maybe the ears that god gave us millions of years ago were less than perfect and have improved through evolution.
Sorry I couldn't help myself!

One day Larry had a room and a SS amp, speakers, a sources, cables, power conditoners and whatever else. Then a sales rep shows up in his room with a tube amp. The amps are swapped, and the "presence" is improved as perceived by Larry. On this basis, the room does not come into question, nor do any of the other components of the system.

The problem is not that "Science" can't measure the subtle differences, the problem as I see it is that there are so many factors at play that are interelated that it becomes extremely difficult to setup an experiment or model that can test the effects of each and every factor in relation to all the others given all the possible permutations and combinations.

In the end Charles I agree with you it comes down to using your ears (the god given ones or the evolved ones) to determine your personal preference through a process more a kin to art than pure science.
