Batteries! I wish I had some batteries. No, I just have a trained rat. He runs on a wheel that turns a precision built German generator that powers an exquisite Japanese linear power supply. Dead quiet setup with $27,000 interconnects - - as you can imagine. Carefree listening except for a little problem I’m having with the rat’s perpetual incentive food feeding machine (PIFF) that I DIY engineered: the coconuts get stuck.
