it's funny that a review on the C807 tower says that the S606 set for $400 sounds better than the pair of C807 towers he bought for a lot more money. He sent back the C807 tower because he said it's not worth any more money than the S606? Ha.
I too love that S606 set. It's been on sale for nearly a year at that price now,(and even once a bit cheaper) --- but it's a near unbelievable value. It does sound incredible for that price! A buddy in KC recently bought the set and hooked it up to an SR-805 receiver. I couldn't beleive you could get five speakers that sounded of that good quality for $400 shipped.
Those deals have been going on for a while now but, they are still a good value. I bought my s506 5.0 and my s606 5.0 set from vanns and love them both. Looks like they are just now advertising them though.
