I heard the system last year while it was still in its prototype stage. I was amazed by how it sounded, but a comparable Axiom system (4 M2ti, one VP100, and an EP125) would definitely sound a lot better due to the larger speakers. I have a pair of M22s now they are so much better.
In my opinion, the only reason to go with the Ventriloquist system over an Axiom system is if you absolutley can't afford to pay more, or your spouse / significant other won't allow any large speakers into the house.
Keep in mind that even when you're just listening to stereo music, the Ventriloquist system will use the center channel's drivers to fill in the audio gaps left by the satellites. This compromise system really messes with imaging and soundstage, which is why it's marketed mainly for HT and not music.
