I currently own Eltax Symphony 6 Front Floorstanders, Mission 77c Centre, Mission 771 as rears and Yamaha 305 Subwoofer. Although I have been relatively happy with them, I'm thinking of upgrading the Eltax to Mission 773e's. Will I see a big difference in quality or could the money be better spent??? If so on what?? (Are the Missions a good choice?) I have also noticed quite a few threads talking about 'Large' & 'Small' settings for speakers. I understand the reasons for pushing the bass to the sub in movies, but does the same go for music???? I'm guessing (dumb-ass) that I will need to keep the sub on for listening to music?? All help and suggestions appreciated!!! Stace.
