I am in the process of upgrading my current HT system. I used to live in an apartment. I have the onkyo 605 receiver and V5 Paradigm Monitors.The front stage is a pair of titans on stands and CC-290. For my rear surrounds I decided to use a pair of mini monitors, also on stands. Now I am living in a house, all my equiptment is in the finished basement,which is much larger than my apartment was. I upgraded the receiver to an Arcam AVR600. Now I need to get some new speakers. I would like to get something that is going to fill the entire room. The bookshelf speakers I have right now are not going to cut it. I do have the SVS SB-12 sub,so I have that covered. I also would like to use a real surround sound speaker this time for the rear. Right now I have around $4500 to spend. System is used for watching movies,do a little videogaming and also listening to some music. Little bit of everything. What should I take a look at?
