I built this for a friend who used it for a couple years and he changed his system. I took it back and made some slight adjustments in parts and wiring.

  • AMB Sigma 11 power supply
  • 4 inputs and 1 output
  • Alps RK27 volume pot
  • grayhill selector switch
  • Aeon polypropylene caps (these were previously used when I put them in so they appear a bit beat up but they all measured correctly.
  • 75% of the chassis has dampening to reduce ringing
-custom nameplate (put this here to cover some holes I had made for leds)
- back of chassis says “Dun Mei Audio” which is just the company that made the chassis.

Asking $450 shipped. Please only Conus.
