I have an LG soundbar (around $800) that I got primarily so I wouldn’t use my system for movies so much, i.e., to preserve tube life and have decent sound from the tv that my wife can operate. The LG sounds pretty good until I turn on the main speakers. Even dialogue is more understandable from the 2-ch system.
The LG is adequate for background music, but even the most modest 2nd system of any Audiogoner is likely better for music.
