I was originally planning on going with a Paradigm setup, but after reading a lot of reviews and threads on this site I have decided to switch to Axiom. I had picked out the M50ti QS8 VP-150 and I thought I was all set. Tonight I got the Sound and Vision buyers guide and noticed that the 60's have midrange drivers, whereas the 50's do not. The upgrade is close to $200, is it worth it? Yes, I'm a neophyte.
