The Parasound Halo P 7 Preamp is a problem solver. The problem is the gap between home theater systems and hi-end stereo systems. Many home theater buyers are fond of the stereo systems that they already own (and paid big bucks for), those that don't already have a stereo might find that they can afford a lot more two channel gear than 7.1 channel gear and since 90-100% of their music collection is two channel.. well, you get the idea. But unless you are a hifi nut like me, you don't have a room dedicated to the stereo and another dedicated to the home theater.
