About 2 years ago, I was thinking about going down the home theater path. I stumbled across the Primare P30 and couldn't believe it's sonic qualities with my 2-channel system. I was never that impressed with home theater anyway and I was immensely impressed with my 2-channel. Yes I do have a Sony DVP s9000es for the occassional movie, but it's still 2-channel.
As for not wanting surrounds and and center ch? I've heard some expensive surround systems over $50k and was never impressed with their sound. Not to mention, that purchasing more speakers, cables, and amplifiers would not be cost-effective to me. Not to mention having my room filled with this eyesore.
Bottom line is that I am a firm believer that if you aquire the appropriate 2-channel system and set it up properly, it will sound absolutely wonderful with movies also. It may not give you the complete surround sound some dream of, but if the movies is that good and your 2-channel system is that good, you'll never miss the other channels anyway because your senses are probably already consumed.
