If your looking for a decent surround sound system, I would seriously consider the B&Ws at half price. Try to find bookshelves that all match. If they're magnetically shielded, see if you can get a total of 5 (4 plus one used for the center channel). Nothing will ruin a surround sound system more than a small, inadequate center speaker.

If you're into classical music, you should think about an SACD player. There are tons of classical SACDs currently available, and they are still making them.

Look for a higher powered Yamaha, Harmon Kardon, Denon or Onko 5.1 or 7.1 receiver.
