If you know of any other similar equipment, please feel free to share them! I think not. I should live so long as to share with you all the high end snake oil audiophile products I have run into. You really got to be kidding. Just go to any audio site and read the ads. The shorter list would be those commercially available that aren't snake oil. Which is an indication of just how far afield high end has gone vs the idea of high fidelity. Maybe a better discussion would be hi-fi vs high end.
