I was in the market for a “flagship” amp but still didn’t know what type of headphones I preferred: Dynamic, Planar or Electrostatic. While I’ve yet to hear an electrostat, I’ve found so far that I prefer the planars to dynamics. When I subsequently opted to go full-planar (for...” --Schopenhauer

The differential topology uses Lundahl amorphous core input transformers to provide passive noise-free voltage gain selectable to 6dB or 12dB. The novel MOSFET based output buffer couples to the headphones through nickel core output transformers, and the DSHA-1 can drive both balanced and unbalanced...
