The audio setup for a home theater system is very much the same as the ideal audiophile setup for stereo. The trick is to not allow the video screen to interfere with the acoustic performance not to allow the addition of rear speakers or subwoofers to detract from the key goal, overwhelmingly delivered by the front speakers, - the ability to play music. 

There is another complicating factor in home theater design. That is aesthetics. Very often high end home theaters are pictured with inwall speakers - virtually invisible. 

From a high fidelity audio point of view, this a huge compromise. In order to set up a natural soundstage, loudspeakers - any loudspeakers, not just Newform Ribbons - have to have space around them. Place the speakers as far out from the wall  as possible without blocking off part of the screen from any seating position.

Inwall speakers simply generate more baffle bounce and front wall reflection. Although they may be able to blast large amounts of sound at you and the center channel speaker might be able to help anchor the audio images, the overall effect is more like an acoustic assault from several points rather than a naturally rendered 3 dimensional soundfield. 

There is no reason a home theater room cannot do as good a job with music as a dedicated high fidelity room. As long as the screens are flat and the loudspeakers are well placed, acoustically speaking, home theater rooms and high end audio rooms can be identical. 

If the front speakers aren’t set up to reproduce music well, then they will do a poor job on home theater as well. 

With just the same toolbag of tricks you developed in your pursuit if high end audio, you can make create your own audiophile home theater.
