Regardless of what is being played- HT, music videos or 2 channel, my prior comments apply regardless. In a nutshell, **all** single-box audio systems are compromised in order to get everything in one box. The more the separate aspects of a HT system are broken out to separate components, the more **potential** exists for vast improvement.
Back in 1999, Stereophile, at a Stereophile Show in NYC, set up two Home Theater rooms side by side. The two rooms were identical (being in a hotel) and the video equipment was identical as well. One used a regular home theater receiver/processor, the other used separates. A poll that they took showed that 90% of people visiting both rooms thought that the room with the high end audio system had a better picture!
