I've had a few 5.1 systems in the past (energy, Polk audio speakers) but I found while the center channel quality is excellent there's just too much bass. Even at low volumes the bass disturbed others in the home (even after playing with eq, boosting center channel, and enabling night mode on the receiver). Currently I have an LG Gallery TV. I like the ease of just using TV for audio and even after raising the volume it doesn't vibrate the whole house.
