That has been the going price on Amazon for quite a while now. The price has been creeping down over the past couple of months. I am wondering if this is a push to eliminate the stock for a new release from Onkyo. Either way, this HTiB has gotten very high reviews all over the web and here on AVS, so you can't lose getting it now.
