I'm very much debating on getting the new VP180 vs my VP150, especially hearing Steve's positive report. The one time I can really say that I notice a difference between the M80s and my 150 is when I run Audyssey, there seems to be a pitch difference as the test tone switches to the centre channel. I'm thinking that the new centre would be virtually seemless in that respect.

Half of communication is listening. You can't listen with your mouth.
