I would deff reccomend the B&W 600 line, if you could a couple changes would make this quite the set up. Change the 685 for 683, dont bother with the 684 the 683's are a much better speaker. You get the 800 series midrange driver, and two larger bass drivers. And go for the 610XP or the 608XP if the have one, 608 is entry level decent performance. But the 610 is better and the XP is much better, I believe the XP has a better amp and a larger magnet.
As for your Receiver I would suggest a Pioneer Eliete VSX-21 (i cant remember which way their models go) but any of the high end Pioneers are great. Great sound, lots of features, and the best quality in the business. Or the high end Denons like the 4000 series or even the 3000 or 2000 series, stay far away from anything else in their line for receivers though.
Pioneer Eliete BDP-23 for a blu ray, but if you can stretch get the BDP-09, its the best player I have seen yet.
Whats do you have for a TV?
