Hello all, this is my first post. I currently have the m50's as my fronts but I am thinking about upgrading. I have found the m70's for a pretty good price and was wondering what everyone thought about that upgrade. Is it worth it or are there other speakers that would be a better upgrade option? I also have m40's for rears, cs2, dsw pro 600, and denon avr-888 receiver. Any opinions would be appreciated.
