This is my first post. I am an HTF virgin so please be gentle. I recently made my first significant HT purchase and bought Monitor 5s and a CC-370. I originally went into purchase the mini-monitors but thought the 5s were much nicer. One day, being an idiot, I listened to the Studio 40s and thought they sounded great. Big mistake, I'm hooked. Would it be a big mistake to purchase Studio 40s to replace the Monitor 5s as my fronts and switch the 5s to my rears (will replace small Cambridge Soundworks Dipoles)? Given, that I would wait to upgrade the CC-370 to the Studio CC. Also, would it make sense to switch the CC-370 to the rear when I upgrade to the Studio CC or would I be better off selling the Monitor Speakers and start from scratch with the Reference Series? The bottom line is would Reference speakersup front and Monitors in back sound terrible? Additionally, I have a Cambridge Soundworks Basscube 8 as my subwoofer. Would it make more sense to replace the subwoofer before I get new front speakers. And, finally, I plan on purchasing a new receiver, eithera Denon 3802 or an Integra 7.2. I don't know if this would affect anyone's recommendations. I would really appreciate your advice and help. Thanks in advance.
