First off, Happy Holidays to all! Being Christmas, I ended up with a bit of extra cash on me today. I remember another thread someone posted with the Rti4's for $150 shipped; Amazon is still selling the pair at this price. With a little cash in my pocket, I debated upgrading to these from my M30's in my 2 channel setup (see sig). Unfortunately, there is no where to audition these anywhere near where I live. So...before I decided to just go on a wing and try it, I wanted to see what you all thought. For a 2 channel system, primarily used for music, are the Rti4's a significant enough upgrade over the Monitor 30's to warrant buying a pair? Thanks, and enjoy the holidays!
