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

Since "holography" is the last stage of development in the audio progression, there is a possibility that it's not relevant in your stage of progression.

Orpheus10,

You’re absolutely right. It’s a matter of priorities.
 Although you can’t  possibly understand it, it is not necessary for many of us to have a holographic presentation to get the most out of the music.
 When I was growing up, I got most of the extensive listening repertoire I now have through a table radio.  The genius of the music flowed through and inspired me.  I didn’t need to have pinpoint sonic accuracy to “get the message.”
 Striving for sonic perfection is putting the cart before the horse. The music comes FIRST.
Enjoy your hobby, but don’t try to convince us that the you can’t get a supreme aesthetic experience without holography.

By your logic, a person sitting in the first row of a concert and ostensibly getting a more “holographic” picture of the sound, is having a better musical experience than someone sitting in the fifth row or tenth row or balcony.

I don’t think that’s the case.

Orpheus10,
Your sliding door experience got me thinking about the glass I have over a large piece of art in my listening room. It is also hung on a side wall (much like your sliding door). First I tried a heavy handmade blanket over it. My impression was "who turned up the bass". I belive what was actually happening is it was sucking the highs & some of the midrange out of the room. Didn't like it much. So now I have it covered with light cloth. This is an improvement. Increased bass without the objectionable suck of midrange/highs. This also increased focus of the soundstage. Thank You!    

Boxer12, Often reflective side walls can be conquered by simple, but radical toe of the speakers, with out the need of using ugly treatments on the walls to deaden high frequency reflections. Often, not always. Give it a try if you already haven't. It worked for me. FWIW there are other benefits to this type of speaker set up as well.
