I second the sub comment. A good sub can really make or break your system. Look at some of the internet direct dealers (epik, HSU, Axiom, etc...) for a good sub.
As far as rear speakers, I personally wouldn't worry about them too much. They are the least important speaker to worry about.
Are you listening to a lot of 2 ch. music, or more so movies? If music, then put your money in the front left and right speakers. if more so movies, a good center channel is paramount.
My second system is all def. tec. (BP7006, pro center 1000, BPX1.2 surrounds) and I enjoy it. The energy stuff isn't bad either. Bring some CDs/BDs to Magnolia next time you go and spend some time listening to both brands and see what you like better; however, I strongly suggest making sure everything is hooked up and setup properly before demoing speakers. The last time I was at a Mag. store i demoed some B&W speakers, thought they sounded like garbage, and found out at the end of the demo that the tweeters had been smashed. I also demoed some Martin Logans for about $6000 a pair, and they also sounded like garbage. I looked behind the receiver and saw they were wired out of phase, corrected the problem, and they were great! All that is to say that you shouldn't base your decision off of one demo at one store, make sure everything is hooked up properly and take your time.
Hope this helps.
