Way back when, I purchased new the Altec Lansing 911 with the 420A Santana speakers. The transisters don't last long and after too many repairs, I am "modernizing." The Santanas stay, added is a Pioneer Elite VSX 52TX, a pair of Mission 772 speakers and a single Sonus Faber Electra for a center. Is this making sense? Will they work together? My ears aren't that good anymore, and I think it is OK, but it is hard to tell. I would appreciate anyone familiar with these components to speculate how well they will work together. The room is large, easy 30' sq. with a 15' ceiling. Glenn
