I was hoping to eventually buy a Pioneer elite vsx 49 txi eventually but now they have the vsx 55 txi. The 49 of course is Ultra certified but the 55 txi is select certified. The 49 goes for almost $4500.00 while the 55 goes for only $1500.00. My theater space has low ceilings from 6-7 feet and the width of the theater is only about 8 feet. The theater is very long however at almost 22 feet. The room is actually an L shape room and the theater is occupying the longer side of the L. I don't want to spend that much more money if the difference between the two recievers is going to be minimal. Any suggestions would be great.
