As I understand it the only difference between the AQ Niagara 5000 and 7000 models is that the 7000 includes an isolation transformer for its lower current outlets. Such a xfmr provides additional noise reduction and isolation for gear connected to those outlets. I've also read that with some gear (mostly tube) there can be some hum issues with the 7000, so in those cases the 5000 is recommended.
