Romy, in this situation, 70' of 8 ga. cable is effectively a variable reactive load and a sink. If nothing else, voltage drop will play a part here, 8 ga. notwithstanding. Whatever you use to span a gap like that will probably need to be biased to keep the line load itself +/- constant, especially considering the small, dedicated-type amps you plan to use. But it's not like you're re-inventing the wheel, here. This sort of run is routine for concert venues, studios, and the like, and the folks who do this day in and day out have straightforward ways of dealing with it. Sure, you will have much more complex demands, but why not start with a solid base? I do like the heavy magnet wire... for AC cords...
