Cayin HA-1A MK2 tube headphone amp Review


” Tube amps live or die by the quality of their output transformers (unless we’re talking OTL designs, of course). I wouldn’t expect Cayin to cram premium Lundahl or Cinemag pieces in there while maintaining that $999 sticker. Cayin’s compromise is to source its own EI core output transformers using Z11 grade silicon steel and a proprietary layered winding configuration. The EI core power transformer is of similar construction, with Cayin describing it as a “large-capacity, low-leakage design.” The goal here is competent — if not exotic — components in a well-thought-out design, making the most of available resources while keeping that reasonable price intact.”
