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

once you hear it the hobby changes for us, forever

I agree. This recently happened for me. There is no going back.

Michael, I'm not very far away from "My musical heaven", and once I get there, I don't think I'll have much time left to post here or anywhere else.

I think it would be helpful if those who have created this optimum imaging in their own home (called holographic) would list the recordings they have heard which can reveal this imaging. FWIW, I think there are not so many, but it would be fun, for me at least, to have some recordings so I could play them on my system and see how far I have progressed in setting up my system, which images quite well, but not yet perfectly, I think.

Sorry to break up this idyllic flow of paeans to holography, but as one who most definitely HAS heard holographic presentation, I can say, while it is very impressive in its own right, it is not the end-all of recorded sound.  It does not, for example, guarantee a full bodied presentation of an orchestra, 
Whereas in smaller forces, it may be effective, in larger forces there can definitely be fullness lacking in a system that otherwise creates holography.
