Besides all that has been said from above, this is an fyi, and my opinion. These two Mc amps are superior in sq than other Mc amps ( I have owned them both, and really liked the 7300 ), as they do not use the Autoformers. They happen to be different in sq, from each other. If your son bridges them, using the 2002 on 1 channel and the 7300 on the other channel, they will not be sonically matched, in a 2 channel set up. Enjoy, be well and stay safe. Always, MrD.
