As I have said here many times before, I am not interested in the 'Closest Approach' thing I am interested in a sound system that stimulates my emotions and sounds the way I expect it to sound. So with that in mind my system should reproduce my choice of music my way and my music includes quite a decent slice of sound effects as well as notated music. One example is the album by Roger Waters known as 'Amused To Death' which is well known for its sound effects and Q Sound effects. If that dog bark doesn't come ninety degrees next to your right ear your system is just not good enough. I honestly don't know what the final spec is on my listening experience but it certainly involves stereo imaging at number one with low bass control at number two.
