Potentially Dangerous, bad quality control (read the update)
21 September 2012
Summary: Thankfully after 20 days of ownership, I checked my surround channels. Turns out my back left channel is defective, as it sounds crackly and only about half as loud as it should. (I verified it was the receiver by swapping the left and right back channel speakers.) Amazon took it back for replacement (with free one day shipping of the new unit!), how awesome is that? Anyway I'd give it 5 stars if it wasn't for the quality control issue.
