I need one for every room...and two for the garage!

That reminds of those over-priced Tripoint Audio grounding boxes with not much more than audiophile air inside. I'm always wary about buying cables or any product for that matter from businesses which encourage some of the indirect marketing we've seen on this site. I don't think that is good business practice, and it is killing what was a once friendly forum for genuine audiophiles to discuss our hobby.

@geoffkait Yeah my friend has a large bank of highly efficient solar PV with mil-spec batteries & is independent of the grid. Hence his audio room runs on 100% battery power which is as good as it gets.
