Get a Yamaha prepro, it will do anything and everything you could imagine, in the digital dsp domain, of course. A Yamaha CX-A5200 is worth its weight in gold, if you can get your hands on one.
Other options are Sony's 360 reality, stuff from Marantz, etc.
I've been hooked on the immersed/surround sound from a set of stereo speakers since my first Carver Sonic Holography preamp back in the day, so I've been on a quest to replicate, but with a highly-refined set of components. Some people want to replicate "soundstage" as a concert, with the sound between their seated position and the speakers. I prefer to be sitting in the middle of the "stage", surrounded by the music.
