Whether an individual channel would get more power will depend on whether it is the channel components or the transformer which hits max first. Knowing that the transformer is capable of 1500 watts total to 4 ohms gives me some idea that the transformer is not the limiting component. Remember too that the 7500 is conservatively rated at 200 WPC. I have seen a review where it put out close to 260 wpc at .05% THD. Most amps are rated at lower wpc and at a higher THD spec. I also think that 3 channels go to one TX and the other two go to the other TX. This thing is a beast and will drive anything.
