<p>As of 2015, my theater system consists of a Marantz AV-7005 pre-pro; a bridged pair of Marantz MA-700 amplifiers driving dual-18" Yamaha subs with 600 watts RMS; an Outlaw Audio 7x125 watts RMS amplifier driving two Marantz HD-880's and five custom Linneams; an XBox; XBox360 w/HD-DVD drive; PS2; PS3; Wii; 16-ch 2TB security DVR w/16 IR/color cameras; Sony CD/minidisc; Roku; Apple TV; OTA HD receiver; 16-channel ethernet switch; primary monitor is Optoma 1080p projector with 204" screen; secondary monitor is a 1080p 65" LG LED; Five theater chair/recliners in one set of two and one set of three; Monster power center; dual dedicated 30 amp breakers on the same 120v mains leg. 12'x2'x2' We built&nbsp; cabinetry with six 8.5"x24" shelves, six 8"x24" shelves, and six 6.5"x24 shelves, all 24" deep.</p>

<p>I used to use nine MA-700's which put 2,000 watts RMS on the floor in total, but several of them developed "popping" on the main power amplifier boards, and to date I've been unable to determine what the problem is. All of them exhibit the exact same symptoms, so I know it's a common failure. I've also run into others on the 'net who have this problem. If and when I figure out what it is so I can fix it, I plan to go back to the seven plus bridged pair configuration. They're great amps -- when they work. :/</p>
