Well reviewed Sony 400W 3.1ch soundbar. As far as I can tell, this is the best price ever for a brand new one. Costco has had them for $579 and TGG has been as low as $535 but I have not seen these anywhere sub-$500. Currently $699 at JB and TGG and $695 at Hardly Normal.

Bought one myself… very happy with it.
Not sure if this is worth the extra over a HW-S60A for $299-350, A550 for $249 or the B450 for $198 at Betta, free delivery. Rtings says they all have very comparable sound - even the A450, $178 at Betta. The A650 has superior sound and comes to $284 on eBay.
