When my wife and I were at Best buy a while back, they had a display set up with a Yamaha soundbar YSP900. We were very impressed, but then again, we have very little basis for comparison. Our audio needs are very simple, but need something to go with our new HDTV. Are these worth considering as an alternative to a 5.1 component system? I REALLY like the simplicity, and am willing to pay a premium, and even sacrafice a bit of sound quality. Looking forward to hearing opinions on the subject. Thank you.
