Oh,yeah. I forgot to put in power conditioning. I have a large solar power generation system that keeps a large battery bank charged for all my daily uses, including my audio system. None of my stuff runs off of street power, since I'm not hooked up to the power pole. I provide all my own electricity. My entire audio system, except the CD player, runs off 12vdc batteries. No grunge, no RF, no ripple, no step-down transformers, no rectifiers, and no power failures. Just flat clean DC power. And no power bill, either.
Does this count toward my audio system budget percentage? If so, I am pushing 50% for power conditioning, and my system cost just jumped to about $25K.
