How important is it for you to attain a holographic image?

I love the spacial ques, without it, it takes me back to the transistor radio days of the 60's

I sorta regard it, anymore these days, as something of a parlor trick, myself. Don't get me wrong, I love imaging - but mainly only when it is playing on the same page as the sound staging. Hate it when the 2 are disconnected from each other.

I've heard (and have owned a couple) systems of lesser quality where it was relatively easy to get a "dimensional" sound from stage rear, and had pretty good imaging as well (at least across the front of the stage), but as things progressed for me over the years, the challenge has been to get the soundfield to fully fill in all the areas in between the front of the stage and the back and do so believably. 

But, I'd say I'm more of a 'line-of-sight' kind of guy...that to me is more like what I hear when I'm out. I listen to about everything at home. Maybe for some small ensembles, it could be an advantage. With most material, I might even find it distracting...I think it can be overdone.

It's true that a live classical performance is not holographic, but with good acoustics it does sound layered. 
That's why I dislike many modern close mic'd recordings. The imaging is flat; how many orchestras have the brass section seated up front?

At home I do enjoy hearing the concert hall ambience. The 3D image is much more audible when the hall is empty.

I like a holographic image with acoustic instruments, like a properly mic'd jazz combo.
A rock band playing electric instruments would not have a naturally holographic image. So it sounds artificial on some recordings.

I'm OK with it being a parlor trick; I don't care how the effect is produced, so long as it's there.  Generally will settle for good 2D, as stereo systems and height is problematical at best.  But I love it when the soundstage stretches way back beyond the plane of the speakers, sometimes beyond the place of the front wall behind them.  This is especially important in recordings of things like concertos, where you really do want the orchestra behind the soloist.

I agree with you  @twoleftears, I love when the 3D image extends far into the front wall. As long as the soundstage is proportional; width, height, and depth, it sounds great to me.
On my system each recording presents different imaging, which I guess means that I'm hearing an accurate reproduction of the original recording. Accurate, of course, also means good tonal quality.
