Dnj, I would say in a controlled environment like home studio, a 2.1 setup might work better than the CPS. The idea of the CPS is creating a 3D stereo sound image on a stage in such a way that the performer can hear himself/herself without a monitor and just about everyone in the audience also hears the same stereo.

I heard both the bigger model and the new V3 at NAMM. Though Aspen told me that the new model sounds exactly the same as the old model, some say that the older V3 sounds better. I don’t know for sure as I have only the old V3.

To say the least, the CPS is a different animal. When I ran my Roland accordion directly through the CPS, it didn’t sound good. Actually it was bad as the left and right of the Roland accordion output bleed into each other. Only when I ran my accordion through a mixer, the CPS sounded very good. When vArranger played multiple instruments, the CPS really shined. All the instruments filled up a large acoustic space.
