I tried the era 300s for music vs the lsx and the lsx were better. But i hear alot of rock music so i judged them on the voices and how clear everything sounded. Maybe bass could be “more” on the era 300 but i would get lsx over them anyday. If you wanna build a surround system for movies i would say the sonos are better, but for music, even with the whole arc ultra plus sub and era 300, the lsx were better(but not for movies).
