Want your thoughts before making a big decision

I just purchased 5 Vienna Acoustics Waltz Grand wall mounted speakers. Music is as or more important to me than theater. Have any of you used these speakers as mains with a sub? I am debating if I should part with the Martin Logans and Krell Resolution and keep all 5 Vienna speakers. If I have a good sub, will the Viennas perform better or worse than the Martin Logans for music. My music preferences are Diana Krall, Natalie Cole, Yo Yo Ma, Winton Marsalis, and so on. I currently have a Krell HTS preamp, Sherbourn power amp, Faroudja CD/DVD, Epik sub, Martin Logan source mains, and Krell Resolution 4 as my center.
I am looking forward to your input
