In my haste to get the 7500 installed into my system I forgot to check the ratings of the trannies. It is quite obvious that the power supply on the right side is more substantial then that of the left. I have seen multichannel amps that implement transformers of the same size to handle two and three channels each. One would assume that those models are taxing the side with the 3 channels on said designs. The ATI/Outlaw seems to offer more iron for the extra channel.
