Onkyo 507 vs. 606

[DJPoop]

Hey everyone, first post here.

I recently decided to take the plunge into the home theater game, and picked up an Onkyo TX-SR507, as well as some Polk Monitor 50's/30's/CS1, and the AA HD-Sub10.

Everything is till in the boxes since I bought all this in anticipation of moving to my new condo soon, but now I'm wondering if I should have opted for the 606 instead. I only plan on running a 5.1 setup, which why I opted for the 507. Not to mention that amazon was running a speacial on it for $292 shipped, so price was also a factor. I'm really trying not to break the bank here since I'll have all kinda of other expenses with the move, and buying new furniture, etc.

Maybe I'm having a little buyers remorse now, and wondering if I should return the 507 for the 606. I'd have to fork out a bit more money, plus have to go through the hassle of returning the unit I have sitting in my living room. Would there be any overhwelming benefits to doing so, or will the 507 suit me fine for what I plan on using it for?

Thanks a lot!
