I beleive what you are talking about is 'Trifield', and while currently only in Meridian gear (and has been for a long time)_ it is actually not their invention. An articale came out a few months ago in Stereophile outlining this technique (which used to be in Yamaha receivers as well.
Does it work? Yes, sounds really good too but makes me feel guilty as though I am bastardizing the original recording. I do like it for some particularly older poorly mixed material as it brings it to life but you will need to experiment with it and as always YMMV.
