Well wasn't that my whole point? There are tons of variables involved, class of operation, power supply designs, etc. But trying to stuff so much in a single 17 format for cost savings just isn't the best idea if long term reliably is taken into account.
For my 7.1 system I'm running 4 separate stereo amps. Also offers the advantage that if one amp goes down I'm still up and running a 5.1 system while that single amp gets repaired/replaced.
BTW, I purchased my Adcom amps used off ebay for just about half the cost of the Monoprice under review.
