I apologize to the OP for the intolerant here who feel it necessary to judge your musical taste & suggest your needs are not worthy of the best sound you can get. Does that make them anti-audiophiles?
Good luck with your search! Sonus makes great speakers - hard to go wrong there. I've not heard the GoldenEar line, but Sandy Gross is an inventive and highly respected designer, and they've gotten great press. Both of the models you mentioned effectively have built-in subwoofers, so they're definitely going to go deeper & louder than the Sonus. I'm curious to hear what you think of their midrange & top end, though.
Please give us your post-listening opinions when you get a chance!
