Indeed the type of speaker positioning configuration your are proposing is, in almost all circumstances, more desirable and will achieve superior results to a symmetrical set-up. I am happy to see that there are some fellow 'goner's here who are familiar with this concept as you will rarely see this type of positioning,not just in peoples homes where it is understandable, considering the aesthetic concerns this type of speaker placement brings to a room, but even in high-end dealer showrooms where these types of considerations should have less bearing. In fact any type of pure symmetrical set-up placement where the speakers are equidistant from all room boundries will almost surely produce acoustical problems such as standing waves. There is an excellent Canadian high-end publication titled UHF that has touted this type of placement scheme with loudspeakers for years. So if you have an accommodating spouse or live on your own I urge all audiophiles to experiment with this type of placement configuration where the loudspeakers form a triangle with the corner of your listening room, I think you will be surprised by the improvement, in the overall performance of your audio system, that can be obtained by this method if performed properly.
